a) Solder the red cable (Vcc +5V - pin Nr. 1 of interface’s connector) to the power distri5V on the KLM-
475 / KLM-509 board. The most suitable place is lead (pin) Nr. 14 of the IC3 (pic. 2.3-3).
b) Solder the blue cable (GROUND - pin Nr. 2 of interface’s connector) to the ground potential on the KLM-475 /
KLM-509 board. The most suitable place is is lead (pin) Nr. 7 of the IC3 (pic. 2.3-4).

a) Detach bunched cables from CN29P and CN30D connectors on KLM-475 / KLM-509 board These cables lead
from instrument’s keyboard (pic. 2.4-1).
b) Plug interface board onto CN29P and CN30D connectors on KLM-475 / KLM-509 board so that flat four-pin
plug on interface’s board is to right (pic. 2.4-2).
c) Plug the connectors of the bunched cables from the keyboard onto the plugs on the interface’s board (pic.
2.4-3). Be careful, the connectors must not be rotated or exchanged. Locks of the connectors must be down.
Bunched cables with black and white colored wires are left (CN29P connector) and bunched cables with yellow
and white colored wires are right (CN30D connector).
d) Plug the flat 4-pin connector of newly installed bunched cables (from +5V, GND and MIDI-IN socket) to the
flat connector on the MIDI-In interface board (pic. 2.4-4). The connector is shaped such that it cannot be
connected the wrong way - there are locks on it.
