HPOD Series 1:1 Redundancy Test
B.4.1 Connection
Step
Task
1
Connect HPOD redundancy loop connectors together using a CA/WR12190-1 redundancy loop
cable.
2
Connect a 28V waveguide switch to the switch connector on the redundancy loop cable.
3
Since both units will be connected to a single EIA-485 bus, they will need independent serial
COMM addresses.
To simplify the setup:
a.
Power up the unit connected to the “SSPA 2” end of the CA/WR11124-1 cable. Using a
EIA-485 connection and a terminal program, set the serial COMM address to “2”
(SPA=0002).
b.
Disconnect SSPA 2 from the EIA-485 cable. Connect the EIA-485 cable to and power up
the unit connected to the “SSPA 1” end of the redundancy loop cable. Confirm this unit’s
serial COMM address is “1”. If required set it to “1” (SPA=0001).
c.
When complete, the SSPA connected to the “SSPA 1” end of the redundancy interlink
cable should have EIA-485 COMM address 1 and SSPA 2 will be COMM address 2.
4
Connect both units to the EIA-485 COMM cable and power both units on. Confirm correct serial
comms by sending them both an RET? query and noting the response.
5
The units auto detect the presence of the redundancy loop cable. Send an RED? query to both
units. Both should report RED=1, indicating proper detection of the redundancy loop cable.
