The logical address switches select the logical addresses for the enhanced
monitor. The top switch sets the most-significant digit, the bottom switch sets
the least-significant digit. It is recommended that you set the address switches to
FF so that the resource manger can dynamically configure the instruments
address; if you select any other address, you must be careful to select a unique
address.
The green READY indicator lights after the power-on diagnostics are complete
and there are no failures. During normal operation, the light flashes if there is a
pending error message. Once all error messages have been retrieved, the READY
indicator stops flashing and remains on.
The amber ACCESSED indicator lights when the MODID line is accessed by
the slot 0 device.
An auxiliary power connector (MONITOR BACKUP POWER SUPPLY) allows
you to apply +5 V to the enhanced monitor board to provide RS-232 commu-
nication with the enhanced monitor while the mainframe is not powered on. The
jumper located just above the power connector determines whether you source
the +5 V standby voltage from the monitor backup power supply connector or
from the 25-pin connector.
