Xycom XVME-202 PAMUX controller module
The XVME-202 PAMUX controller module is a single-high VMEbus-compatible interface to the PAMUX 4, 5, and 6 remote I/O products available from OPTO 22.
The PAMUX is a high-speed distributed I/O system which provides for connection to a VMEbus system through a Xycom XVME-202 module and a 50-conductor flat ribbon cable. The PAMUX system provides a family of Digital and Analog Intelligent Brain Boards that may be daisy-chained to provide a total of 500 I/O points. The PAMUX Brain Boards may be placed at distances up to 500 feet from the VMEbus master controller.
