Note: Format A for the B-row will be used if E7A-H, E8A-H, E9A-H, and E10A-H connect pins 2 and 3. This

format must be used for a 32-bit VME system. Format B for the B-row will be used if these jumpers connect pins 1

and 2. This format is not compatible with 32-bit VME systems.

* Not used

TB1 (2/4-Pin Terminal Block)

This terminal block can be used to provide the input for the power supply for the circuits on the PMAC2

board when it is not in a bus configuration. When the PMAC2 is in a bus configuration, these supplies

automatically come through the bus connector from the bus power supply; in this case, this terminal block

should not be used.

Pin# Symbol Function Description Notes

1 GND Common Reference Voltage

2 +5V Input Positive Supply Voltage Supplies all PMAC digital circuits

3 +12V Input Positive Supply Voltage +12V to +15V; not required on-board;

used on j1 to supply analog inputs

4 -12V Input Negative Supply Voltage -12V to –15V; required for opt-12 ADCs;

used on J1 to supply analog inputs

Note: Unless Option 12 (Analog-to-Digital Converters) is included on the board, only pins 1 and 2 may be provided

on this terminal block.

TB2 (4-Pin Terminal Block)

This terminal block provides the output for PMAC2’s watchdog timer relay, both normally open and

normally closed contacts.

Pin# Symbol Function Description Notes

1 WD_NC Output Watchdog Relay Out Normally closed

2 COM Input Watchdog Return +V or 0V

3 WD_NO Output Watchdog Relay Out Normally open

4 COM Input Watchdog Return +V or 0V

Note: The normally closed relay contact is open while PMAC2 is operating properly – it has power and the

watchdog timer is not tripped – and closed when the PMAC2 is not operating properly – either it has lost power or

the watchdog timer has tripped. The normally open relay contact is closed while PMAC2 is operating properly and

open when PMAC2 is not operating properly.
