SECTION 1
GENERAL INFORMATION
Overview
The Universal LINC232 allows peripheral devices to
be attached to the ISN network to receive and send
data. The Universal LINC232 provides a connection
point for:
VT100 Terminal Emulation (PC connection)
Modem
Printer
1
Along with this upgrade some of the switches were
modified and the baud rates were upgraded to offer
higher speeds. These items are covered more specifically in the Installation section.
NOTE: This manual will refer to both
versions as the Universal LINC232
unless specific differences apply. When
specific differences in operation apply,
they will be referenced at that time.
Facility Manager/YES/IcE/TUP/ISNTools
A variety of mounting configurations provide a very
adaptable device. A 5 VDC Power Supply is also
available to power the Universal LINC232 or it can
be powered via the LAN connector on newer controllers equipped with a USB-style connector. The power
supply also includes the same flexible mounting
options as the Universal LINC232.
The original Universal LINC232 was designed
around the Rev. 77 and older networks. While
communication to newer, UCS-based products
(TDCE, IDC, UDC, etc.) is functional, the save or
restore functions within Facility Manager did not
operate correctly. The IcE engineering tool also does
not accommodate the UDC software in the on-line
edit mode or the save and restore functions.
To accommodate products using the newer UCS
software, the Universal LINC232 was enhanced. This
product is differentiated from the original by the
name “Universal LINC232 UCS” on the metalwork
or the printed circuit board number of
031-02424-001.
NOTE: The Universal LINC232 supports on-line monitoring only and does
not support remote alarm delivery. For
remote alarm delivery, a LINC Guardian Modem is required.
The Universal LINC232 uses a bank of DIP switches
to select communication parameters and node address. The selectable communication parameters are
parity and transfer rate.
NOTE: The Universal LINC232 can
only be powered via the LAN connection on products equipped with a USBstyle connector. Products not equipped
with the USB-style connector must be
powered from the optional 5 VDC Power
Supply.
The Universal LINC232 requires a 5 VDC power
source. If located within 39 in. (1 m) of a controller
equipped with the USB-style connector, sufficient
power can be supplied through the LAN connection
point, either the screw terminals or USB-style
connector. For older style controllers, i.e., those not
equipped with a USB-style connector, or if the
mounting location is not within 39 in. (1 m) of any
controller, the 5 VDC Power Supply must be used to
power the Universal LINCs.
Description
The Universal LINC232 is a small footprint device
which can be located inside most enclosures or
positioned as a stand-alone device within a building.
The Universal LINC232, as well as the optional
5 VDC Power Supply, includes a housing with a DIN
rail mounting clip. Either device can be removed
from the housing and attached directly to a panel or

SECTION 2
NETWORK TOPOLOGY
General
The full range of ISN control products (UDC, TDCE,
FDC, etc.) are able to reside on a Local Area Network
(LAN) with full peer-to-peer communications. The
network architecture supports a potential of 8372
controllers, each one able to communicate to any
number of other controllers on the LAN and outside
of the LAN via a modem to remote facilities.
The entire building or complex may be linked together to form a Building Automation System (BAS)
or Building Management System (BMS).
YORK’s proprietary network protocol is the Integrated System Network (ISN). The ISN network is
RS485, utilizing ethernet principles and background
and foreground communication levels. The data
transfer speed is either 19.2 or 50 kbaud, depending
upon the version of software used. Newer versions of
software allow transfer speed selection to be backward-compatible with older networks.
All ISN controllers have the ability to communicate
directly to all other ISN controllers or devices on a
network or any subnetwork – this is known as “peer
to peer” communication.
Due to the volume of traffic which may be present on
a network, it is often beneficial to divide the network
into subnetworks. Local messages remain contained
within the subnetwork. Full network communication
is then limited to only the data relevant to the other
subnetworks, greatly reducing the network traffic.
A variety of devices may be attached to the ISN
network to enhance usability and functionality. Some
of these devices are:
• The Universal LINC485 configured as a repeater
amplifies the network signal to extend the
physical length of a network or subnetwork
cable. They also extend the number of ISN
controllers by segmenting the network.
• The Universal LINC485 configured as a router
separates subnetworks from the main network.
• The LINC Fiber Optics interfaces the ISN
network with fiber optic cable.
YORK INTERNATIONAL
• The LINC Guardian manages the remote transmission of multiple alarms from the ISN network.
• The Universal LINC232 allows communication
to RS232 devices such as modems, serial
printers, terminals or PC’s.
2
NOTE: The PC must be running a
VT100 emulation program, York Icon
Engineering Software (IcE) or York
Facility Manager for Windows™
software.
Physically, a twisted-pair (2-core) shielded cable is
daisy-chained between the network devices.
Communication Method
The ISN network communicates on a “contention”
basis. Every ISN controller on the network can
transmit a message but only the designated receiving
controller(s) acknowledge receipt. Each receiving
controller sends a receipt back to the sending controller as acknowledgment of the transmission. A calculated checksum is used to verify the integrity of each
message.
If no acknowledgment is received, the message is
automatically retransmitted up to 3 times. After 3
attempts to communicate, the sending controller
starts to increase the amount of time between transmissions. The time increases in intervals of 10
seconds, 15 seconds, 30 seconds, 1 minute, 15
minutes, 30 minutes and then 1 hour if unsuccessful.
Retransmission of the message then occurs automatically every hour until receipt is acknowledged. No
message is ever lost, although message delivery may
be slowed on high traffic networks if not segmented
properly.
If an external device is connected to the RS232 port,
such as a modem through the Universal LINC232,
the retransmission interval between failed communications changes from 1 minute to 15 minutes to 30
minutes to 1 hour, 2 hours, 4 hours and then 6 hours.
Retransmission of the message then automatically
occurs every 6 hours until receipt is acknowledged.

Background vs. Foreground
Communications
The ISN network uses both “Background” and
“Foreground” communication to ensure essential data
is transmitted without delay.
Background communication supports multiple source
messages at the same time, although the speed of
communication may be affected if large quantities of
data are transmitted around the network.
Examples of background communication are:
• Automatic transfer of digital states and analog
values between ISN controllers.
• Analog and Digital alarms to a Universal
LINC232 connected to a PC running the York
Facility Manager for Windows™ software.
• Using a PC running the York Facility Manager
for Windows™ software to read and write data
to and from an ISN controller via a Universal
LINC232.
• Analog and Digital alarms to a LINC Guardian.
Only one foreground communication to a specific
ISN controller can occur at any one time. A “busy”
message is displayed if the ISN controller is already
communicating with another device using this
method. Background communication can occur
simultaneously with foreground communication.
Examples of foreground communications are:
• Manual communications between ISN controllers using the optional keypad/display or Windows™ HyperTerminal software running on a
PC connected to the RS232 port of an ISN
controller.
• Using a PC running the York Facility Manager
for Windows™ software to write data into an
ISN controller via a Universal LINC232.
• Printing of Analog and Digital alarms to a
Universal LINC232 connected to an RS232
printer.
YORK INTERNATIONAL
• Using a PC running the York IcE to Save or
Load an ISN controller Configuration via a
Universal LINC232.
• Using a PC running the York Facility Manager
for Windows™ to Save or Load an ISN controller Configuration via a Universal LINC232.
Speed of Communications
The ISN network communicates at either a 19.2 or 50
kbaud rate. The Universal LINC232 is switch selected to communicate at 4800, 9600, or 19,200
(19k2) baud rates through the serial RS232 port.
The typical response time between ISN controllers
for automatic transfer of data or alarms is
100 milliseconds.
Each Universal LINC485 Repeater and Router
increases the typical response time by
100 milliseconds.
Summary of ISN Network Restrictions
• The maximum single length of a network or
subnetwork is 4000 ft. (1200 m). This can be
extended to 12,000 ft. (3600 m) using two
Universal LINC485 devices configured as
repeaters. This provides a maximum combined
network end-to-end length of 36,000 ft. (10,800
m).
• A Universal LINC485 configured as a repeater is
required every 4000 ft. (1200 m) or 32 nodes. A
node is any device which uses an RS485 driver,
such as an ISN controller, Universal LINC485 or
Universal LINC232.
• The maximum number of nodes on a main
network is 92 plus two Universal LINC485
devices configured as repeaters. A maximum of
91 plus two Universal LINC485 devices are
allowed on a subnetwork.
• When the main network or subnetworks are
extended between different buildings, the
ground/earth voltage of the buildings must be at
11

the same potential. If this cannot be guaranteed,
the network connection between building(s)
should be a fiber optic cable with a LINC Fiber
Optic device fitted in each building to interface
onto the ISN network.
• The LINC Guardian should be used where it is
expected multiple alarms will be transmitted via
a modem to a remote Facility Manager for
Windows™ or multiple destinations. It acknowledges receipt of any alarm to a transmitting ISN
controller and can store up to 20 alarms in each
of the 8 standard ISN Alarm Classes.
• All node numbers connected to the LAN Port 1
of a Universal LINC485 configured as a repeater
must be lower than the node address of the
repeater. All node numbers connected to the
12
LAN Port 2 of a Universal LINC485 configured
as a repeater must be higher than the node
address of the repeater.
• Each ISN controller must have the node switch
set to a unique address number between 1 and 98
per subnetwork. The node switches are used for
filtering messages at a Universal LINC485
configured as a repeater which also must have a
unique node number. The node switches on a
Universal LINC485 configured as a router set
the subnetwork address and must be between 1
and 98, with the main network automatically
being network address 99. Communications
between ISN devices on the same network or
subnetwork(s) should use network 0 (zero) as the
network address.

SECTION 3
INSTALLATION
Installation Guidelines
This manual assumes the installer is competent in
environments with moving machinery, and is able to
recognize and protect against any inherent hazards,
such as, but not limited to, refrigerants, oil, corrosive
chemicals or gases, materials under pressure, rotating
parts, and both high and low voltages. Each of these
items has the potential, if misused or handled improperly, to cause bodily injury or death.
It is the obligation and responsibility of the operating/
service personnel to identify and recognize inherent
hazards, protect themselves, and proceed safely in
completing their tasks. Failure to comply with any of
these requirements could result in serious damage to
the equipment, as well as severe personal injury or
death. In addition to following standard local, state
and country codes and procedures, it is recommended
that a lockout procedure be used to prevent inadvertent start up of equipment during installation and
maintenance procedures.
All wiring should be carried out in a safe and neat
manner and should always comply in all respects to
the latest edition of any local, state or country codes
that may be applicable. The wiring should be installed in a manner that does not cause a hazard and
is protected against electrical and mechanical damage.
Care should also be taken when mounting enclosures
so access to other equipment within the vicinity is not
restricted.
Environment
YORK ISN equipment must be installed in an
environment that is protected from the direct influence of the elements and is within the following:
Temperature: 32 to 122° F (0 to 50° C).
Humidity: 10% to 95% non-condensing.
The unit should never be mounted outside the confines of a building. If this cannot be avoided, it may
be mounted inside an enclosure rated at IP65/NEMA
4X or greater. In addition to protection against the
YORK INTERNATIONAL
elements, the enclosure must be capable of maintaining the circuit boards at the required temperature and
humidity. This may require the addition of a fan or
heater to maintain the temperature and humidity
inside the enclosure.
WARNING: Never install the components in an element that does not
meet the minimum environmental
requirements.
3
Electrical
Refer to the table titled Recommended Cable Specifications to determine suitable wire sizes to connect the
line voltage feed the devices. The line voltage power
source should be “clean,” separately fused (for either
110 or 240 VAC), and isolated, (using a control
transformer) from other equipment in the plant room
that may generate EMI interference.
Electrical Noise
All electrical equipment has the risk of being affected
by external electrical noise. This noise may take the
form of Radio Frequency Interference (RFI) or
Electro-Magnetic Interference (EMI). To minimize
the affects of electrical noise, mount equipment in a
location away from all possible RFI and EMI
sources. These include high voltage cables, high
voltage transformers, breakers, and high frequency
drives.
Keep line voltage switching loads a minimum of 6 in.
(152 mm) away. Any high voltage equipment, such as
transformers, high horsepower electric motors or high
frequency drives, should be kept a minimum of 30 ft.
(9.1 m) away.
All high voltage wiring (>75 volts) must be run in
conduit and kept separate from low voltage communications wiring. This greatly reduces network
communication problems.
13
INSTALLATION
FORM 450.20-N17 (702)
Ground/Earth
All ISN controllers are designed to use the building
ground (earth) as a reference
point. This electrical orientation helps maintain all electronic components communicating to the controller within
their specified voltage limits.
Protection of Communication Ports
GRD.
RAM 5
CAUTION: The controller must
connect to a true building ground.
Failure to do so may cause equipment damage and will void all
warranty claims.
Electrical grounding also protects network devices
from the effects of lightning strikes. When lightning
strikes near an ISN installation, it alters the potential
of the building’s ground. If an ISN controller has
been properly grounded, it will respond to this
change much faster than if the ground connection is
inadequate. Controllers that are poorly grounded
provide a lower resistance path through their signal or
power connections than the actual ground of the
building. Under these circumstances large surge
currents may flow through the controller and result in
component failure.
An example of a poor ground would be a galvanized
steel cold water pipe. As the pipe corrodes it no
longer acts as a true ground. The corrosion acts as an
insulator, raising the potential of the pipe with respect
to earth ground.
YORK strongly recommends that the building’s
ground be checked prior to the start of the installation. The power distribution panel should be checked
to ensure that it is not connected to a corroded or
galvanized pipe. As a minimum, it must be connected
with 14 AWG wire.
The most common circuits damaged are communication components, such as RS485 and RS232 drivers.
When using RS485 technology it is possible that
electrical disturbances, such as voltage spikes, can
damage a circuit board. Newer ISN controllers
include tranzorbs at the RS485 ports to protect
against damaging electrical spikes and stray voltage.
It is recommended that all devices on an RS485
network be equipped with protection against electrical disturbance.
Cable Specifications
Power Cables
CAUTION: Aluminum wire is
absolutely not acceptable.
The power cable should be at least an 18 AWG
copper wire rated for 10 amps per core at 250 volt
AC. If the power cable uses three conductors, the
ground conductor must be, as a minimum, the same
size with the same current carrying capacity as the
live and neutral conductors.
All ISN devices should be wired to a non-switched,
fused spur to prevent the power from being turned off
accidently. The supply spur should be protected with
a either a suitable fuse or an approved power breaker.
The input line supply voltage should be fused. For a
115-volt line voltage use a 10-amp fuse or breaker.
For a 230-volt line voltage use a 5-amp fuse.
The fuse or breaker should be located within a
reasonable distance to the controller so the power can
be turned off any time the unit is serviced.
Network and Sensor Cables
Cables come in many types. A balance between cost
of the wire and the simplicity of the project determines the variety of wires used. Quite often a single
type of wire or cable may be used for nearly all
wiring on a project, even though it greatly exceeds
the requirements for a particular sensor or application.

INSTALLATION
FORM 450.20-N17 (702)
To attach any of the devices, hook the lip of the
mount over the edge of the DIN rail. Press the bottom
of the device until the mount “snaps” over the lower
lip of the DIN rail.
Summary of Mounting Recommendations
• Always mount ISN devices inside the confines
of a building or inside an enclosure suitably
rated for exposure to weather.
To remove a module, pull the lower lip of the mount,
which is exposed below the housing, down until the
lower lip of the DIN rail is clear. Tilt the device and
lift it off the top lip of the DIN rail.
• Never mount ISN devices under or beside pipes
carrying water or chemicals.
• Never mount ISN devices near high voltage
cables, high voltage transformers or breakers, or
close to high frequency drives.
In some situations it may be desirable to remove the
Universal LINC from the housing and attach it to the
5 VDC Power Supply. The housings are modular and
can be separated by using a screwdriver pressed
between sections. When the Universal LINC is
removed from the housing it may be attached to the
5 VDC Power Supply using the two 2.5M x 5 screws
located on the top surface of the power supply. The
assembled unit may then be clipped to a DIN rail.
• Never mount ISN devices in a location where
the environment could be outside the specified
operating specifications.
• Never mount ISN devices on a vibrating surface
without first employing some form of mechanical dampening.
Hardware Configuration
Panel Mounting
DIN Rail Mounting
When a DIN rail mount is not desired, the Universal
LINC may be removed from the plastic housing by
separating the sections of the housing. The Universal
LINC may then be attached directly to a suitable
panel using 1/8 in. (4 mm) screws. Likewise, the
power supply may also be removed from the plastic
housing and attached directly to a suitable panel. The
option to attach the Universal LINC to the top of the
The Universal LINC232 provides several different
options for installing within a network. Each device
is shipped within a plastic housing with a DIN rail
mounting clip. The optional 5 VDC Power Supply
also uses a plastic housing with DIN rail mounting
clip.

Power Connections
Universal LINC Connection
Because the Universal LINC is a small device, power
can be drawn from a controller if located within
39 in. (1 m) of the controller. When a Universal
LINC is not located within 39 in. (1 m) of a controller a separate power supply must be used. The
terminals GND and 5VDC at the LAN port should be
connected directly to the 5 VDC Power Supply.
An alternative method of connecting a Universal
LINC is to use a patch cable (Part No.
371-01429-000). This patch cable takes advantage of
the additional, USB-style connector on the newer
controllers. The patch cable combines the power and
communication wires into a single cable and doesn’t
require disconnection of the existing network cables
from the standard LAN connector.

The optional 5 VDC Power Supply is supplied as
either 115 or 230 ±10% volts AC at 50/60 Hz frequencies. Maximum output of the Power Supply
Module is 300 mA at 5 volts DC.
A properly color-coded wire must be obtained locally
to conform to local, state and country regulations for
connection of the 115/230 VAC line voltage. Two
leads, red and black, from the power supply connect
to the Universal LINC.
DANGER: Disconnect any line
voltage power supply at the source
before attaching wiring to prevent
possible electrocution.
The line voltage power supply should be wired to a
non-switched fused spur to prevent the power from
being turned OFF accidentally. A fuse or breaker
rated at 5 amps (115 VAC input) or 3 amps (230 VAC
input) should protect the controller from overload.
The 5 VDC Power Supply requires a 3-conductor,
power cable for the line voltage power supply, similar
to the one used by most computers. It may use a
typical plug in connector (ideal for connecting to the
Auxiliary Power Outlet in a UDC) or have bare wire

at the other end (for connection to a circuit breaker
box). It is recommended that the line voltage supply
cable be installed within suitable conduit if it is run
outside the enclosure. Ensure that all wiring meets
local, state and country codes, as well as follows
NEC recommendations.
To install the Power Supply Module:
DANGER: Always disconnect the
power before working inside or
around an electrical enclosure.
1. Mount the 5 VDC Power Supply using either
the DIN rail or panel mounting method.
2. Attach the black power lead from the 5 VDC
Power Supply to the GND terminal and the red
power lead to the 5 VDC terminal of the LAN
port.
3. Install conduit, if necessary to meet code,
between the device and an appropriate line
voltage power supply at a circuit breaker or
fuse box.
4. Install a 5 amp (115 volt line voltage) or 3 amp
(230 volt line voltage) fuse or circuit breaker in
the line voltage spur. Be sure to place a label on
the circuit breaker indicating the Universal
LINC power shut-off point.
5. Plug the line voltage cable into the receptacle
on the 5 VDC Power Supply. The plug is keyed
for correct orientation.
6. Either plug the line voltage cable into a standard receptacle (such as is used in the UDC) or
attach each conductor to the fuse or circuit
breaker according to regulations.
Wire Connections
The Universal LINC232 has two ports. The LAN port
is for connection directly to the network as a node or
to a controller as an external device. The LAN port
utilizes the RS485 standard. The RS232 port is for
connection to serial devices using the RS232 standard.
RS232 Connection
The RS232 standard requires a 3-core shielded cable
for transferring data. However, not all serial devices
transmit data in the same manner. In particular,
printers use the CTS pin. Also, there are two types of
connector; a 9-pin and 25-pin.
NOTE: The old style Universal
LINC232 requires the DIP switch
settings to match the type of device and
connector type to communicate with a
serial device.
To properly connect the cable to the RS232 port, refer
to the figure titled “Typical RS232 Wire Connections.” Determine the type of device and connector
style and attach the appropriate wires. Be sure to
attach the shield/screen to the GND terminal.
LAN Connection
The RS485 standard uses a twisted-pair, shielded
cable to transfer data. A 5 volt DC signal is used as
the signal and, if located within 39 in. (1 m) of a
controller (signal generator), can be used to power the
Universal LINC.
An optional patch cable (Part No. 371-01429-000) is
available to simplify connection to the LAN. (This
cable is included with the Universal LINC232
Commissioning.) This patch cable allows quick
connection to the LAN when using newer controllers,
such as the TDCE, IDC and UDC.
To connect the patch cable to the USB-style socket on
the controller, simply insert the USB-style plug into
the socket on the controller. At the Universal LINC
end, remove the standard screw terminal connector
and attach the patch cable. The patch cable is prewired to simplify connection.
The figure titled “Typical RS485 LAN Connections”
provides shows the different methods for connecting
the LAN. Note the different methods for connecting
YORK INTERNATIONAL

INSTALLATION
FORM 450.20-N17 (702)
the GND and 5VDC terminals. Power is always
connected to the LAN side.
When making RS485 connections, the cable shield
(screen) should be connected at one end to a ground
and left open (unconnected) at the other. Ideally, the
shield continues as close as possible to the device
unless the device is inside an enclosure. The Universal LINC232 provides a terminal for this purpose
labelled SCREEN.
Inside an enclosure, the shield should be connected to
a ground point as soon as possible after the cable
enters the enclosure. In this case, do not use the
SCREEN (or USHL if connecting to a controller)
terminal but connect to the closest ground/earth point.
Switch Settings
In order to provide the most flexibility with the least
amount of effort required, the Universal LINC232
uses a set of DIP switches to configure the device. As
the DIP switches are positioned, the software makes
adjustments to ensure proper operation for the
selected functions.
The Universal LINC232 (Board No. MR022) and
Universal LINC232 UCS (Part No. 371-03785-001 or
371-03876-001) differ in the terminology used for the
switch settings, particularly regarding parity. With the
Universal LINC232, the parity settings were based on
a particular device and therefore labelled by device
type. For the Universal LINC232 UCS, the parity
settings are selectable by the user and not tied specifically to a device. In addition, the transfer rates were
also increased to more accurately reflect typical baud
rates.
There are 12 DIP switches on the Universal
LINC232. They are categorized by Parity or Device
Type, Device Baud Rate, Node Address, and Communication Rate.
Parity or Device Type
The parity can be selected to accommodate virtually
any device that communicates on an RS232 protocol.
To determine specifically what the setting should be
for each device, consult the documentation for that
device. There are some typical settings which can be
used in lieu of documentation. The original Universal
LINC232 used these typical settings without specifically calling out the parity settings.
Most devices allow the parity to be set as desired.
The Universal LINC232 UCS allows the parity to be
set to match the device instead of forcing the device
to be adjusted to the Universal LINC. The following
table shows recommended settings for various YORK
products. These can, however be modified as desired.

Device Baud Rate
Communication Switch
The transfer rate of the devices which can be connected to the Universal LINC232 vary. To select the
appropriate transfer rate, use switches B1 and B2.
Four transfer rates are available, from 1200 to 9600
baud, for the original Universal LINC232 and three
rates are available, from 4800 to 19,200 (19k2) baud,
for the current, UCS variant.
The Communication Switch (CS) sets the Universal
LINC232 to communicate at the network transfer
speed. This can be either 19.2 or 50 kbaud. Set
switch CS to OFF to operate at 19.2 kbaud and ON to
operate at 50 kbaud.
NOTE: If connecting to an existing
network using Rev. 76 software or
earlier, LAN transfer rates are limited to
19.2 kbaud. For new installations, Rev.
77, and UCS software, the transfer rate
should be set to 50 kbaud.
Node Address
Each device on an ISN network must have a unique
identifier or node address. This node address can be
any number between 1 and 98.
Switches 1 through 64 are used to set the node
address. These are binary switches which, when
summed, add up to the node address.
The CS switch position is only examined when the
device is first powered up. Any changes made to the
CS switch are ignored unless power is removed and
re-applied.

Continuity and Isolation Checks
CAUTION: Always check for isolation and continuity before applying
power to a network.
A common cause of failure of network devices is
incorrect wiring. Incorrect wiring typically causes
short circuits along the network wiring resulting in
defective RS485 transceivers. Other possible symptoms of faulty wiring are open circuits and the
presence of voltage collected by the shielding.
devices on the network. With the LAN connectors
removed from any devices:
1. Check for open circuits on the P2 and P3
conductors. Resistance should be low between
the ends of each conductor. If not, check for
breaks in the wire.
2. Check for short circuits by observing resistance
between the P2 and P3 conductors, P2 and
ground/earth, and P3 and ground/earth. The
presence of a resistance other than infinity
indicates a break in the wire.

The RX LED is green and the TX LED is red.
Status LED
A red Status LED indicates operating condition. The
Universal LINC232 UCS follows the UCS LED
conventions for flash rates.
The TX LED indicates that the Universal LINC232 is
