Connecting to bright blue
Communication between the bright blue controller and a VRI-1S3 reader interface is via RS-485 protocol. Any
one of the Device connectors (Device 1-1 through 2-16) on the bright blue controller can be used to
communicate with TB1 for RS-485 communications and TB2 for power on a VRI-1S3. The example below shows
connections between Device 1-1 on the bright blue controller and TB1, TB2 on the VRI-1S3.
