1. Apply the power by plugging the power into any power terminal block connector on the rear panel. The
power source can be from a power adapter or from a power card (installed either on the left or right side
of the rack).
2. Once the power is applied, all the LEDs will flash for a second.
3. The "PWR A" or "PWR B" LED on the front panel(s) of the Base and Expansion boards will light
according to which power terminal block connector (A or B) is connected to. Both LEDs will light when
power redundancy is utilized. The "Vcc" LED should be lit, indicating an adequate operating voltage is
being derived from the power source.
4. Make sure all DIP switches on the front panel are switched to the up "Off" position before testing.
5. At the rear panel, connect the RS-232 or RS-422 signal into the RJ-11 jack (CH1) "MAIN" on the Base
Board. The "MAIN" and "BRD" LEDs from CH2 to CH8 on the front panel should light to indicate a
valid signal input. If the "MAIN" and/or "BRD" LEDs do not light, it usually indicates a poor or incorrect
connection at the input port. If this is the case, double-check your connections and confirm them with
the RJ-11 connection diagrams on page 8.
6. If the aux channel(pins 2 & 3) is used, SW1_5 must be enabled to allow for the handshake signal. To
see the status of the aux channel, SW1_1 must be set to the down "On" position. The "MAIN" and "BRD"
LEDs from CH2 to CH8 on the front panel should light to indicate a valid signal input. If the "MAIN"
and/or "BRD" LEDs do not light, it usually indicates a poor or incorrect connection at the input port. If
this is the case, double-check your connections and confirm them with the RJ-11 connection diagrams
on pages 7 and 8.
When SW1_1 is enabled, you will see the "AUX-BRD" LED lit, the "AUX-RSP" LED will be Off (it will
light up once it receives the signal from the RTU or the signal is loopback via hard wired on pins 2 & 3),
the "AUX-ENB" will be lit, indicating that the aux channel is being used, and the "AUX-LED" LED will
be lit, indicating that the aux channel is being monitored for status purposes.
7. Once the "BRD" LED lights (indicating a valid signal input), a Local Loopback test can be conducted by
setting the "LOCLB" DIP switch (SW1_2) to the down position (see Chapter 3 - Testing &
Troubleshooting).
8. Return all DIP switches to the Left for normal operation.
