Status Indicators
There are two power status indicators on the ACB labeled D7 and D9:
• D9 is the ±15V DC voltage-OK signal
• D7 is the +5V DC voltage present signal.
Interface Module (IFM)
The interface module makes all your connections to the ACB. The pin numbers
listed on the following pages refer to the IFM pin numbers.
