16 USEFUL FUNCTIONS

CONFIGURING THE SQL CONTROL SIGNAL

If you connect an external device, such as a TNC or PC, to
the ACC 2 connector on the rear panel, you can configure
the SQL control signal condition with the MSQ pin and
SSQ pin of the ACC 2 connector.
Refer to "INSTALLING AND CONNECTING THE
TRANSCEIVER" for the details of connector.
SELECTING THE MSQ/SSQ LOGIC
You can configure the logic of the SQL control signal of
the MSQ pin and SSQ pin.
1 Press [ADV.] (F) from the Menu screen to open the
Advanced Menu screen.
2 Access Menu 18, "MSQ Logic State" (Main band), or
Menu 19, "SSQ Logic State" (Sub Band).
3 Press [SELECT] (F4) to allow editing of the parameter
box.
4 Press [-] (F4) or [+] (F5) to select "Low" or "Open".
The default is "Low" for both the main band and the sub
band.
5 Press [ ] (F1).
6 Press [MENU] to exit.
Note:
◆ The VoIP application installed in a PC detects the busy state even
after the transceiver power ( ) has turned OFF, select "Open" for
Menu 18, "MSQ Logic State" (Main Land), or Menu 19, "SSQ Logic
State" (Sub Band). As well, you must configure the logic of the
busy state detection in the VoIP application to be the same as the
transceiver configurations.

] (F1).
Operation
Fixed at low (inactive).
The SQL control signal becomes high (active)
regardless of the matching status of the received
CTCSS frequency.
If the CTCSS signaling is active, the SQL control
signal becomes high (active) when the received
CTCSS frequency coincides with the CTCSS
frequency configured for the transceiver.
If the CTCSS signaling is inactive, the SQL control
signal becomes high (active) when the CTCSS
frequency is received, regardless of the matching
status of the received CTCSS frequency.
The SQL control signal becomes high while the
transceiver is transmitting.
The SQL control signal becomes high while the
transceiver is transmitting and receiving.
If "Sql" and "Send" are configured, the SQL control
signal becomes high.
