ELECTRICAL DETAIL
For electrical detail on Infinity, Horizon and ELA machines refer to the
respective Technical Reference manual. For GSX and Lt machines only, a
PCADADIO card is used. The PCADADIO card is a multi-purpose I/O board
with the following functions:
• 8 Differential Multiplexed Analogue Inputs.
• Two Analogue Outputs.
• 16 Digital I/Os.
• 3 Counter-timer Channels.
The operation of these functions are controlled using the PC XT bus and link
options.
