Description
This signal provides a fully buffered
signal representing the MDXII unit's
programmed setpoint level. This signal
will source and sink 5 mA through a 2-
kW resistor. Its impedance is 100
See Table 9-2 on page 9-15 for the
standard analog signal scalings.

This signal provides an accurate 10 V
reference (10V ± 10 mV). Its
Ω
impedance is 100 .
Note: Limit current to 2 mA.
Use this 0 to 15 V signal to provide for
high accuracy at low output levels.
When this signal is low, the HALO
feature, if supported, is active (see page
5-19).
We recommend that you reference all
digital inputs, except the interlock
signals, to this pin.
This signal is used interchangeably with
OUT COM.D (pin 37). It is a dedicated
return to internal system ground, then to
chassis ground, and finally to protective
earth-ground.
This signal is used interchangeably with
IN COM.D (pin 36). It is a dedicated
return to internal system ground, then to
chassis ground, and finally to protective
earth-ground. All digital outputs should
be referenced to this pin.
