7.3 Initial operation
The power connector's (8) pin-out in top view (refer to fig. 2) is assigned as
follows:
Bottom to top, left to right. Thus pin 1 is located at bottom left, pin 2 above pin
1 etc. Pin 15 is at bottom right, pin 16 at top right.
Pin 1, 2 = -12 V (labelled with a triangle)
Pin 3-8
= GND (regarding ground, 0 V), located outward on all jacks
Pin 9, 10 = +12 V
Pin 11-16 = not connected
To hook up power to the module, connect one of the IDC-connector of the
included flat ribbon cable to the box header (refer to fig. 2). Observe guide key
for the polarity of the connector in order to avoid pin reversal. The red tag of
the cable is to match the triangle-label.
7.4 Calibration
All trimmers are 12 gauge trimmers, i. e., 12 turns are needed to cover the
entire range. Trimmers P5, P7, P6 and P8 increase their parameters when
