Old-Style Repeater/DAC Board

The "Old-Style" Repeater/DAC Board is used to communicate with the old Water-vapor board and the old Ozone board. It uses the old-style 56-pin subbus cable which generally requires a split cable to avoid noise on the command strobe and command enable lines during initialization.

The jumpers on the board determine the address range for the D/A channels and the interrupt configuration. The jumper settings we have used historically are:
