Address Switches (SW2)
The RDR2S-A and I8O4 modules have 5 address switches (see page 31).
Ensure that the address of the RDR2S-A or I8O4 module does not
conflict with the address of any other device on the RS485 bus.
NOTE: Before changing the position of the address switches, remove the 12/
24 VDC supply power to the RDR2S-A or I8O4 module and wait for the Power
LED to go off. Changes will not take effect until after the power is restored.
