5. For the Ethernet 8-way Relay Board:
a. Disconnect the power connector. [1]
b. Configure the address of each relay board chronologically using jumpers JP7 1
to 16. When all jumpers are populated, the address is 1. When a jumper is
removed, the corresponding number will be added to the network address.
For example, if jumpers 1, 4 and 8 are removed, the address will be 1+1+4+8=14.
The first relay board in the network MUST be configured as address 1, the
second as address 2 etc. Addressing, for example, 3 boards in the network
with addresses 3, 6 and 20 is not allowed, as their addresses must be 1, 2 and 3.
Relay boards and energizers are addressed separately from 1 to 32. Relay boards
and energizers are addressed separately from 1 to 32. On the FG7 module, an
address offset of 32 is added to all relay boards. Therefore, relay board 1 will
be referred to as 33 (1+32), relay board 2 as 34 (2+32) etc. on the FG7. [2]
c. Ensure jumpers JP5 B and C are populated. Jumpers JP5 A and D can either be
populated or not. [3]
d. Connect the relay board to a port on the ethernet switch (the port number
does not matter) with an ethernet cable. [4]
e. Power up the relay board (The NEMTEK Power Pack can be used to power the
relay board).
