d. 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. 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. [4]
e. Ensure jumpers JP5 B and C are populated. Jumpers JP5 A and D can either be
populated or not. [5]
f. Connect the GND, A and B wires coming from the
DATA OUT of the previous RS485 network device
to the DATA IN GND, A and B terminals of the relay
board. [6]
g. Connect the GND, A and B wires going to the next
RS485 network device to the DATA OUT GND,
A and B terminals of the relay board. [6]
h. Power up the relay board once all data connections in the daisy chain ring has
been completed. (The NEMTEK Power Pack can be used to power the relay
board)
