SV-COM-C25 Installation, Configuration, and Testing
16-10 SkyView System Installation Guide - Revision S
Shielded cable between SV-COM-425 Pins 1 and 2, and SV-INTERCOM-2S Pins 1 and 25:

This cable consists of two wires plus shield.

Use one of the wires to connect SV-COM-425 Pin 1 to SV-INTERCOM-2S Pin 25.

Use the other wire to connect SV-COM-425 Pin 2 to SV-INTERCOM-2S Pin 1 (see
instructions below - Terminating Shielded Cables to Pin 1 of SV-INTERCOM-2S).

On the SV-COM-425 end, continue the shield as far into the connector as possible until
you're forced to pare it back to access the two inner wires. Put some heat shrink tubing
over the shield to keep it electrically isolated - the shield at the SV-COM-425 end of this
cable is not electrically connected at the SV-COM-425.

On the SV-INTERCOM-2S end, prep the shield into a "pigtail" so that you can solder to it
(see below).
Terminating Shielded Cables to Pin 1 of SV-INTERCOM-2S

Four connections terminate into SV-INTERCOM-2S Pin 1:
o SV-COM-425 Pin 9
o Shield of the cable from SV-COM-425 Pins 9 and 10
o SV-COM-425 Pin 2
o Shield of the cable from SV-COM-425 Pins 1 and 2

Rather than trying to terminate these four connections directly to the SV-INTERCOM-2S
Pin 1, we suggest connecting a wire to Pin 1, then bond all five connections together.
One method is to tie-wrap the bundle of wires and shields together, twist the wires
together, and solder the five wires and shields. After the solder cools, use heat shrink
tubing to insulate the connection.
