e) Overlap the connection and R51 resistor with the insulation tube and heat it (with a hot-flue pistol for
example) until it shrinks tightly to the resistor and the wire (fig. 2.5.9).
f) Wires from Nr. 11 to Nr. 16 of the 16-core ribbon cable are connected to pins 2 to 4 of CN01 connector as
shown in table 1. Since solder pads of the CN01 connector are not accessible directly (they are on bottom side
of the KLM-366 board), the wires are soldered to some via-pads on the board what conforms to the pins of the
CN01 connector (fig. 2.5.10).

g) Solder both Nr. 11 and Nr. 12 wires of the 16-core ribbon cable to the “+5V” via-pad. It conforms to pin 2 of
the CN01 connector (fig. 2.5.10).
h) Solder both Nr. 13 and Nr. 14 wires of the 16-core ribbon cable to the “GND” via-pad. It conforms to pin 3 of
the CN01 connector (fig. 2.5.10).
i) Solder both Nr. 15 and Nr. 16 wires of the 16-core ribbon cable to the “-5V” via-pad. It conforms to pin 4 of
the CN01 connector (fig. 2.5.10).

a) The interface board will be placed
on the rear panel of the instrument –
between the power supply board and
power cord sub-panel (fig. 2.6.1).
b) Cleanse the part of rear panel inside
of the instrument for the interface
board placement (fig. 2.6.1). It is
necessary to remove a paper label
usually glued in this area. Use a
chemical cleaner to remove all dirt and
grease.
