Analog Out connector
Normally an appropriate output cable should be used, depending on whether
your system has current or voltage output. It is also possible to configure your
own output cable, bearing the following description in mind.
The female 15-pin D-Sub Analog out connector contains the following signals:
1. Current return
2. Current return
3. Current return

When using the ITZ FLEX ULTRASTAB in current out mode (no VOM
installed) only pin 1, 2, 3 and 9, 10, 11 should be used.
•
Pin 9, 10, 11: Is the current output from the
ITZ FLEX ULTRASTAB.
•
Pin 1, 2, 3: Current return path.
When using the ITZ FLEX ULTRASTAB
in voltage out mode (VOM installed)
pin 1–9, pin 2–10 and pin 3-11 must be shorted. This will loop the current
output to the VOM. The output signal
V
S
High is then present at pins 4 and 5
and the output signal
V
S
Low is then present at pins 7 and 8.
IMPORTANT:
The sense pins (
V
S
High Sense on pin 4 and 12, and
V
S
Low
Sense on pin 7 and 14) must be connected to
V
S
High Out and
V

Low Out
respectively.

4 mm “Banana” Current Output terminals
Two standard 4mm banana jacks are available for easy connection to a low
impedance current measuring DMM.
CAUTION:
These terminals should be shorted when not in use by use of the
supplied shorter plug.
IMPORTANT:
The ITZ system is tested for EMI conformance against industrial
standards. Use of the unshielded 4mm banana current output port can be
critical under circumstances with a high level of external disturbance.
