12.3 Panel Board Cables
The panel board ships with a 10-wire video cable (DSC part no. 698010) and a 2-wire power
cable (DSC part no. 698011). These are intended for use with the optional accessory video board
and a Jupiter-MM (JMM) power supply when these boards are used together with the
Prometheus-LC CPU and panel board.
The 10-wire video cable connects the VGA output of the video board to pin header J25 on the
panel board. J25 is compatible with a number of companies’ PC/104 video boards that provide a
10-pin connector for the video out.
12.4 Panel Board Hardware
The panel board also comes with mounting hardware for installing it and the CPU into an
enclosure such as the Pandora system.
