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
Communications, Inc.
Equipment Location
The TC2400 and TC2401 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, heavy duty power supplies, etc. 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 @500mA power supply is adequate for the TC2400/2401. The power plug is a
terminal block connector with positive & negative polarity indicated on the rear panel of the unit. Alternate
power sources are available as an option (see Chapter 6 - Specifications).
Installation Procedure Summary
The TC2400/2401 is designed for quick and easy installation. Before installing, however, make sure all DIP
switches on the front panel are in the up (Off) position and double-check the polarity at the DC power's
terminal block connector.
Installation Procedure:
A. Install the Master unit first. Run an Optic Loopback Test (see page 18).
B. Install one Slave unit. Run a Remote Loopback Test (see page 19).
C. Connect the RS-232 or RS-422/485 signal to the Master unit (See pages 10, 11 & 12).
D. Install additional Slave units. Run Local and Remote Loopback tests.
E. Verify system integrity:
At Master unit: check "RxA," "RxB," "Sync-A," "Sync-B," "LPA" and "LPB" LED indicators.
At each Slave unit: check "RxA," "RxB," "Sync-A," "Sync-B," "A2B," and "B2A" LED indicators.
Verify and record the optical cable loss for each link in the system after installation is complete. This reading
will both verify the integrity of the circuit and provide a bench mark for future troubleshooting efforts (see
Chapter 3 - Troubleshooting).
