After taping the wire ends individually, wrap the entire connection
with electrical tape as shown. This will help protect from moisture and
prevent the wires from breaking contact.
Wiring Diagram "B"
If your VHF radio or other device requires true RS-232, you will need to
remove the diode and resistor built into the end of the Cuda 240i data cable.
You will notice near the end of the cable a segment protected with black
heat-shrink. To connect the Cuda 240i to a true RS-232 radio, first
remove the Uniden adapter segment of the cable as shown in the
following figures.
For Wiring Diagram B installations, remove the Uniden adapter
segment at the end of your data cable as shown at left. Snip off the end
of the cable protected by the black heat-shrink. At right, we have used
clear heat-shrink for clarity, so you can see the diode and resistor
protected within. Remove this portion of the cable.
