Unpacking the Unit
Before unpacking any equipment, inspect all shipping containers for evidence of external damage caused
during transportation. The equipment should also be inspected for damage after it is removed from the
container(s). Claims concerning shipping damage should be made directly to the pertinent shipping agencies.
Any discrepancies should be reported immediately to the Customer Service Department at TC Communi-
cations, Inc.
Equipment Location
The TC2200/2201 should be located in an area that provides adequate light, work space and ventilation.
Avoid locating it next to any equipment that may produce electrical interference or strong magnetic fields,
such as elevator shafts and heavy duty power supplies. As with any electronic equipment, keep the unit from
excessive moisture, heat, vibration and freezing temperatures.
Dry Contact Alarm Relay
A terminal block connector at the rear panel provides for the Dry Contact Alarm Relay Normally in the
OPEN position, any alarm condition will force the switch to a CLOSED position. This relay can be used in
conjunction with an external device (such as an RTU) to signal an alarm condition to the Host.
Power Supply
Typically, a 9V to 12V DC power supply @650mA is adequate for the TC2200/2201. The power plug is a
terminal block connector with positive & negative polarity indicated on the rear panel of the unit. Two
connectors, labeled "PWR A" & "PWR B" are provided for a built-in power redundancy feature. While only
one connection is required to power the unit, both connectors can be used simultaneously. When power
redundancy is utilized, both power "A" & "B" share the load. If one power supply fails, the other will take
over the full load. Alternate power sources are available as an option (see Chapter 6 - Specifications).
Installation Procedure Summary
The TC2200 and TC2201 are designed for quick and easy installation. Before installing, however, make sure
all DIP switches on the front panel are in the Up position and double-check the polarity at the DC power's
terminal block connector(s).
A. Connect the Host's RS-232, RS-422 or RS-485 signal (see pages 8 & 9 for pin assignments) to the
TC2200 (Master) unit's DB25 connector.
B. Configure the Master unit's internal DIP switch (see pages 6 & 7) and connect power to the Master unit.
Run an Optic Loopback Test and Local Electrical Loopback Test (see pages 15 & 16).
C. Connect the RTU's RS-232, RS-422 or RS-485 signal to the TC2201 (Slave) unit's DB25 connector.
D. Configure the End Unit's internal DIP switch (see pages 7 & 8) and connect power to the Slave unit.
Run an Optic Loopback, Local Loopback and Remote Loopback Test (see pages 15, 16 & 17).
E. Configure and connect additional Slave units into the bus (see page 4 for application topologies). Run
an Optic Loopback, Local Loopback and Remote Loopback Test for each additional unit installed.
F. Verify System Integrity:
At Master and Slave units, check "Rx-A," "Rx-B," "SynA" and "SynB" LED indicators.
Verify and record the optical cable loss for each link in the application after installation is complete. This
reading will both verify the integrity of the circuit and provide a benchmark for future troubleshooting efforts
(see Chapter 3 - Troubleshooting).
