The following figure depicts how dual SV-COM-T8s 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 SV-COM-T8 wiring
from the single SV-COM-T8 to SV-INTERCOM-2S previously shown.

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 102 – Dual SV-COM-C25 to SV-
INTERCOM-2S.
