Transmit Interlock
When two SV-COM-X83 radios are installed, the TRAMIT INTERLOCK pin can be connected
to reduce “break-through” (noise being heard as the squelch opens) in one COM radio when
the other COM radio is transmitting. The PTT IN signal (Pin 15) is connected to the TRANSMIT
INTERLOCK (Pin 18) of the other radio, as shown above in Figure 181 – Dual SV-COM-C25 to SV-
INTERCOM-2S.
Dual SV-COM-T8 to SV-INTERCOM-2S Harness Construction Notes
Shielded cable between SV-COM-T8 #1 Pins 1 and 2, and SV-INTERCOM-2S Pins 1 and 14:
This cable consists of two wires plus shield.
Use one of the wires to connect SV-COM-T8 #1 Pin 2 to SV-INTERCOM-2S Pin 14.
Use the other wire to connect SV-COM-T8 #1 Pin 1 to SV-INTERCOM-2S Pin 1 (see
instructions below - Terminating Shielded Cables to Pin 1 of SV-INTERCOM-2S).
On the SV-COM-T8 #1 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-T8 #1
end of this cable is not electrically connected at SV-COM-T8 #1.
On the SV-INTERCOM-2S end, prep the shield into a "pigtail" so that you can solder to it
(see instructions below - Terminating Shielded Cables to Pin 1 of SV-INTERCOM-2S).
