Shielded cable between transceiver module Pins 23 and 9, and SV-INTERCOM-2S Pins 1 and 25:
• This cable consists of two wires plus shield.
• Use one of the wires to connect transceiver module Pin 23 to SV-INTERCOM-2S Pin 25.
• Use the other wire to connect transceiver module Pin 9 to SV-INTERCOM-2S Pin 1 (see
instructions below - Terminating Shielded Cables to Pin 1 of SV-INTERCOM-2S).
• On the transceiver module 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
transceiver module end of this cable is not electrically connected at the transceiver
module.
• 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 Transceiver module Pin 1
o Shield of the cable from transceiver module Pins 1 and 2
o Transceiver module Pin 9
o Shield of the cable from transceiver module Pins 23 and 9
• 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. The following figure depicts how dual transceiver
modules are connected to an SV-INTERCOM-2S. Note that the additional connections
between the SV-INTERCOM-2S and other devices that it connects to are not shown.
Note that the associated SV-COM-PANELs are also not shown; there are no changes in
the SV-COM-PANEL to transceiver module wiring from the single transceiver module to
SV-INTERCOM-2S previously shown.
