Setting Module Address and EOL Termination
To set the module address:
 To set the module address, set SW1 (16 position rotary switch) to a number
from one to eight. Every reader on a bus must have a unique address.
To set RS-485 EOL (End of Line) termination:
 Set SW3-5 to the On (closed) position if the module is the last unit on the
bus. If the module is not the last unit on the bus, SW3-5 should be Off
(open).
Figure 6 on page 10 shows how to connect ARM-1 relay modules to the RM-4
outputs and how to wire NO (Normally Open) and NC (Normally Closed)
supervised inputs.
