Enhanced Monitor Board Jumpers

The Enhanced Monitor board has two jumpers accessible from the rear of the mainframe. Figure B±3 shows the factory default settings of these jumpers.

+5V Standby sourced from monitor backup power supply (default)

+5V Standby sourced from P9, pins 8 & 21

MODID12

You can also select the source of the +5 V Standby voltage. If you source the +5 V Standby voltage from the +5 V external supply (Monitor Backup Power Supply connector), then the external supply will provide the backplane with the +5 V external voltage (1 A maximum). If you source the +5 V Standby voltage from the 25-pin connector, you must provide the +5 V to pins 8 and 21 of the 25-pin connector. The default jumper setting is to provide the voltage from the external source (+5 V external power supply).

The Enhanced Monitor can answer to the slot 1 or slot 12 MODID line for the VXI configuration manager. The default position is slot 12 since it is most likely to be empty. Slot 1 is available if you use a 2 slot embedded controller.
