A Mini-D 36-pin connector for first digital amplifier command outputs and current feedbacks. This
connector provides the interface to a fully digital amplifier for the first channel.
Note that current feedback data must be in serial digital form, already converted from analog in the
amplifier.
Note:
The dual axis unit, 3U042, has two jumpers on the logic board (603728-10x
/bottom board). If these Jumpers are ON then the shield of the PWM cable
connects directly to the GND, if the jumper is OFF (default) there is a 0.1mfd
capacitor in the way to the GND. These jumpers are E2 and E3, for channels #1
and #2 respectively. For revisions -104 and above.
