16 OTHER FUNCTIONS Control of External Devices TX Inhibit in Busy State (when Squelch is Open) When transmission is inhibited in the busy state, pressing [SEND] on the front panel or [PTT] on the microphone does not execute transmission while this transceiver is busy. Configure in Advanced Menu [12] "TX Inhibit While Busy" Setting Value Off (default)/ On Reversing the PKS Signal Polarity Short-circuiting the PKS terminal to GND places this transceiver in the TX mode. This polarity can be reversed according to the device to be connected. Configure in Advanced Menu [11] "PKS Polarity Reverse" Setting Value Off (default)/ On Off: Short-circuiting the PKS terminal of the ACC 2 connector to GND places this transceiver in the TX mode. On: Applying a voltage of 3 V to 5 V to the PKS terminal of the ACC 2 connector places this transceiver in the TX mode. USB Keying This function is compatible with PC applications for controlling the different behaviors including CW keying, RTTY frequency shift and PTT/SEND (TX/RX switching) using the RTS/DTR signal of the COM port. It allows the above behaviors to be assigned to the RTS and DTR signals of the 2 virtual COM ports (Standard and Enhanced) during USB connection. Off: Disabled Flow Control: Behaves as a hardware flow control signal for command communication. CW Keying: Behaves as a CW keying signal. RTTY Keying: Behaves as an RTTY frequency shift key signal. PTT: Behaves in the same way as PTT (SEND). DATA SEND: Behaves in the same way as DATA SEND (PKS). Configure in Advanced Menu [17] "Virtual Standard COM Port - RTS" Setting Value Flow Control (default)/ CW Keying/ RTTY Keying/ PTT/ DATA SEND Configure in Advanced Menu [18] "Virtual Standard COM Port - DTR", [19] "Virtual Enhanced COM Port - RTS" or [20] "Virtual Enhanced COM Port - DTR" Setting Value Off (default)/ CW Keying/ RTTY Keying/ PTT/ DATA SEND ● To switch the COM port or exit the application in the PC application for performing transmission on the transceiver using the USB keying function, be sure to complete the transmission before doing so. Otherwise transmission error may occur on the transceiver. ● If the COM port for outputting the USB keying signal is not selected (open) in the PC application that is using the USB keying function, the signal for USB keying may be accidentally transmitted. Press [ ] to turn off the power of this transceiver or disable the USB keying function temporarily until the preparation on the PC application is completed. ● "RTTY Keying" can only be configured for 1 out of the 4 signals (duplicate configuration is not allowed). ● When this menu is configured to "RTTY Keying" (during RTTY operation via USB keying), RTK of the ACC 2 connector will be disabled. ● Please use the latest virtual COM port driver. Decoded Character Output This function outputs characters decoded by the built-in decoder of CW/ RTTY/ PSK from the virtual COM port (Enhanced). The baud rate is also variable. Turning ON/OFF Decoded Character Output Configure in Menu [7-03] "Decoded Character Output" Setting Value Off (default)/ On Configuring the Baud Rate of the Virtual COM (Enhanced) Connector Configure in Menu [7-02] "Baud Rate (Virtual Enhanced COM)" Setting Value 9600/ 19200/ 38400/ 57600/ 115200 (default) [bps] 16-12

●
To switch the COM port or exit the application in the PC
application for performing transmission on the
transceiver using the USB keying function, be sure to
complete the transmission before doing so. Otherwise
transmission error may occur on the transceiver.
●
If the COM port for outputting the USB keying signal is
not selected (open) in the PC application that is using the
USB keying function, the signal for USB keying may be
accidentally transmitted. Press
[
]
to turn off the power
of this transceiver or disable the USB keying function
temporarily until the preparation on the PC application is
completed.
●
“RTTY Keying” can only be configured for 1 out of the 4
signals (duplicate configuration is not allowed).
●
When this menu is configured to “RTTY Keying” (during
RTTY operation via USB keying), RTK of the ACC 2
connector will be disabled.
●
Please use the latest virtual COM port driver.
Decoded Character Output
This function outputs characters decoded by the built-in decoder
of CW/ RTTY/ PSK from the virtual COM port (Enhanced). The
baud rate is also variable.
