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.
