16 OTHER FUNCTIONS Switching the Reference Signal External frequency input (10 MHz) from the REF IN connector on the rear panel can be used as the reference frequency of this transceiver. The input impedance is 50 Ω. • Inputting a reference signal with a high degree of accuracy from an external source to this transceiver and using it as the reference frequency helps to enhance the frequency accuracy of this transceiver. • The standard input level is 0 dBm ±10 dB. Configure in Advanced Menu [4] "Reference Signal Source" Setting Value Internal (default)/ External Internal: Uses the built-in reference signal transmitter of this transceiver. External: Uses the external frequency input from the REF IN connector as the reference frequency. ● This transceiver may not function properly if the reference input level from the external source is low or if there is deviation in the frequency. ● Please refer to (17-2) for the adjustment of internal reference frequency. Switching the CTCSS Mute Operation Configure in Advanced Menu [13] "CTCSS Unmute for Internal Speaker" Setting Value Mute (default)/ Unmute • When combining the use of CTCSS to prevent unwanted signals such as noise from being transmitted from the base station to the Internet while operating this transceiver as a VoIP amateur radio base station, configure to "Unmute" so that the status of the operating frequency can be verified. Doing so outputs all RX audio signals from the speaker regardless of the matching status of the CTCSS frequency. Only RX signals with a matching CTCSS frequency are output from the ACC 2/USB port. Configuring the SQL Control Signal When operating this transceiver with an external device such as PC connected to the ACC 2 connector on the rear panel, the status of the SQL control signal for the PSQ pin of the ACC 2 connector can be configured. Configuring the Logic of PSQ Configure the SQL control signal logic of the PSQ pin. Configure in Advanced Menu [14] "PSQ Logic State" Setting Value Low (default)/ Open • Configure to "Open" to enable the VoIP application installed on the PC to detect a busy state even when the power of this transceiver is OFF. Also, configure the busy detection logic of the VoIP application so that it matches that of this transceiver. Configuring the PSQ Output Conditions Configure the transition in the status of the SQL control signal output from the PSQ pin. Select Advanced Menu [15] "PSQ Reverse Condition". Setting Value Off/ Busy/ Sql (default)/ Send/ Busy-Send/ SqlSend • The PSK behavior in each of the setting is as follows. Setting Value Off Busy Sql Send Busy-Send Sql-Send Behavior Fixed in the low (inactive) state. Switches the SQL control signal to the high (active) state regardless of the matching status of the CTCSS frequency received. When CTCSS is ON, SQL control signal switches to the high state when the CTCSS received matches the CTCSS configured on this transceiver. When CTCSS is OFF, SQL control signal switches to the high state when a signal is received by this transceiver regardless of the matching status of CTCSS. Switches the SQL control signal to the high state when this transceiver transmits a signal. Switches the SQL control signal to the high state when this transceiver transmits or receives a signal. Switches the SQL control signal to the high state in the same way as when the setting is configured to "Sql" and "Send". Switching the COM Connector Signal The CTS/RTS terminal of the COM connector on the rear panel can be configured such that it operates in the same way as the PSQ/PKS terminal of the ACC 2 connector. 1 Configure in Advanced Menu [16] "PSQ/PKS Pin Assignment (COM Connector)". Setting Value Off (default)/ On Off: The COM connector processes both the CTS and RTS signals. On: The signals of the CTS and RTS pins of the COM connector are replaced by PSQ and PKS signals respectively. • A message to confirm the behavior of the COM connector is displayed. 2 Reboot this transceiver. After this transceiver reboots, the new settings are applied. The behavior of the output signal of each setting is as follows.
