B6 BRAIN BOARD
Note: Information on the B6 applies to revision G or later. For revision F or earlier, refer to Opto 22 form #154.
The Pamux B6 is an addressable analog brain board that can control up to 16 input or output points in
distributed I/O applications. The B6 is designed for use with Opto 22 mounting racks that feature header
connectors, including the PB4AH (four points of analog I/O), PB8AH (eight points), and PB16AH (16
points) using Opto 22 Classic analog modules.
The B6 features a 50-pin female connector to attach to a mounting rack and two 50-pin male connectors
to attach to the Pamux bus or a terminator board. Up to 32 B6 brain boards may be linked on a single
Pamux bus to control up to 512 points of analog I/O.
The B6 includes an on-board microprocessor that continually scans all I/O points on the mounting rack,
performs necessary conversions, and then updates a dual-port RAM. The host computer transfers data
along the Pamux bus by reading from or writing to the dual-port RAM.
