Connecting the ACS IV Controller to the ACS IO
A maximum of 16 ACS IO’s can be connected to a single ACS IV Controller.
When there are multiple ACS IO, RS485 communication cable must be installed using the daisy
chain method.
Failure to do so may cause the ACS IV Controller to malfunction.

CAUTION
• The maximum allowed communication length for the RS485 cable is 1 000 m.
Meaning, that the furthest away an ACS IO can be installed is 1 000 m from the ACS IV
Controller.
• It is suggested to use 18/2 AWG twisted shielded pair cable.
