Connecting Readers to SLC 5/04 Controller – 2 AIC Modules

The SLC 5/04 controller requires two 1747-PIC converters and a
power supply to connect to the second 1747-AIC module.

The end devices on a DH-485 network must be terminated. The
wiring base of the AdaptaScan Reader provides a termination switch.
