Hazardous voltages may be present on modules. Prevent
electrical shock by covering all unused slots and securely
fastening all faceplates.
Des tensions dangereuses peuvent être présentes sur les
modules. Éviter les chocs électriques en couvrant tous les

The Enhanced Monitor is a separate PC board that plugs into the VXI
backplane from the rear of the mainframe. In this way it does not occupy a
user slot on the front of the mainframe. The Enhanced Monitor uses a
standard-defined P1 Connector but a uniquely-defined P2 Connector. It is a
message-based, slave-only VXI interface card, complete with its own VXI
logical address. Refer to Chapter 3 of this manual for SCPI programming
information. This section provides general information about the Enhanced
Monitor.

RS-232 Interface supports communication with a terminal or
computer for remote monitoring purposes only. Refer to Chapter 3 for
SCPI programming information.
-- All SCPI command are supported by the RS-232 interface.
-- The RS-232 interface is set-up only through SCPI commands.
Settings are stored in non-volatile memory. Factory defaults
are:

Ambient Temperature Monitor (
intake air stream path just above the mainframe impeller.
-- A user-defined limit can be set, default is 55 °C.
-- Limit is restored from non-volatile memory at power-on.
-- When the limit is exceeded, the monitor generates a warning
on the display, sets a status bit, the temperature LED flashes,
and the beeper sounds (if enabled).

Power Supply Temperature Monitor (
under a power supply transformer. The reading is indicative of overall
power supply loading.
-- If the temperature exceeds an expected level, the monitor
generates a warning on the display, sets a status bit, the power
supply LED flashes, and the beeper sounds (if enabled).
