Breakpoint and Trigger Terminal Blocks
Both the breakpoint and trigger connectors use a 6-pin removable terminal
block.
The trigger terminal block provides access to the trigger input lines,
shutdown input line, and digital ground. The breakpoint terminal block
provides access to the breakpoint output lines, the +5 V supplied by the
MID-7654/7652, and the digital ground. Figures 17 and 18 show the
breakpoint and trigger 6-position terminal block assignments.

Analog I/O Terminal Blocks
The MID-7654/7652 features two analog I/O connectors.
The analog input connector uses a 6-pin removable terminal block, which
provides access to four analog-to-digital converter channels, an analog
reference voltage from the converter circuit, and an analog input ground
signal.
The analog output connector uses a 5-pin removable terminal block, which
provides access to four digital-to-analog converter channels and analog
output ground. Refer to Figures 19 and 20 for terminal block pin
assignments.
