Chapter 4 - Bench Tests
General
It is highly recommended to conduct these bench tests before actual installation. Bench testing will allow
the user to become familiar with all the functions and features of the TC2100 in a controlled environment.
Knowledge of the TC2100's functions and features will ease installation and troubleshooting efforts later on.
Bench Test with Built-In Signal Generator
The TC2100 has a built-in signal generator. It can simulate a broadcast message from a SCADA host when
th unit is in “master mode.” However, when the unit is in “slave mode,” the built-in signal generator will
simulate an RTU's response message instead. The built-in signal generator is a pulse signal indicated by a
blinking LED. The flash rate is intentionally reduced for easy visual confirmation.
1.
Set up the bench test as shown in Figure 16. At the Master unit, turn "On" the "SIG-GEN" by sliding
ESW3 downward. The "BRD-1" and "BRD-2" LEDs on the TC2100 (Master) should start blinking.
The "BRD-1" and "BRD-2" LEDs on the TC2100s (Slaves) should also blink, indicating receipt of
the Master's broadcast signal.
2.
At any Slave, turn "On" the "SIG-GEN" by sliding ESW3 downward. The "RSP-1" and "RSP-2"
LEDs on the Slave should start blinking. Verify that the Master's "RSP-1" and "RSP-2" LEDs are
also blinking, indicating receipt of the Slave's simulated response.
3.
Disconnect the fiber cable from "RxA" or "RxB" on the TC2100 to simulate a cable breakage. The
"BRD-1" & "BRD-2" and "RSP-1" & "RSP-2" LEDs on the TC2100 (Master) and TC2100 (Slave)
should continue blinking, indicating communication was not disrupted due to the optic cable breakage.
Reconnect the fiber cable & repeat this step for each link between the Slaves and Master unit.
4.
Observe any other flashing LEDs on each unit. Refer to pages 11 & 12 for the LED functions of
the TC2100.
