Connecting to bright blue
Communication between the bright blue controller and a VBB-RI 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 P4 on a VBB-RI. The below example is using Device 1-1 on the bright blue controller and P4
on the VBB-RI.
