26 FUNCTION PORT146 Function Reference Version: 1.11Note:" You cannot use the PF Data PTT port, PF Ext. PTT (Voice) port,and the PF Ext. PTT (Data) port at the same time." The transceiver mutes on the Data CH/GID. The transceiverdoes not transmit the PTT ID even if the PTT ID is configured.26.1.4 CH/GID Select A-DThis Remote CH/GID List port is to be used with theRemote CH/GID List.You can configure the port in the order of the ConfigureCH/GID Select A > CH/GID Select B > CH/GID Select C> CH/GID Select D.26.1.5 DTCThis port allows the transceiver to move to the Data Zone-CH/GID for data communications and activate ARQMode.When performing data transmission in a LTR TrunkingSystem, the transceiver is normally required to link to arepeater prior to each data transmission. Therefore, thedata transmission may fail when the system is busy andthere is no available channel in the repeater. To solve thisproblem, ARQ Mode allows the transceiver to completedata communications in a Trunking system by making asingle link.The transceiver does not transmit the EOT after the ARQmode is linked. This function retains the link by using theHang Time of the repeater while communicating using theACK signals. With this function, you can use the Air Timeeffectively.The transceiver enters ARQ Mode when the PF DTC portbecomes low.The DTC function has priority when the Data Overridefunction is enabled.Note:" During scan, the data channel does not reverted by the PTT." When the PF DTC port becomes low, the transceiver moves tothe Data CH/GID in the Revert Zone." The DTC is not configured when the PF Data PTT port isconfigured as the Function Port." You cannot configure the DTC function if the External PTT(Data) port is not configured.26.1.6 Speaker MuteThe speaker audio output line mutes when this port isused.The transceiver mutes when the PF Speaker Mute portbecomes low. The mute function is disabled when thisport becomes high.26.1.7 Mic MuteThe Mic modulation line mutes when this port is used.The Mic Line (Front Mic, MI2) mutes when the PF MicMute port becomes low. The mute function is disabledwhen this port becomes high.26.1.8 External MonitorThis port activates the Monitor function.The transceiver activates the Monitor function when thePF Ext. Monitor port becomes low. The transceiverdisables the Monitor function when the PF Ext. Monitorport becomes high.Note: You cannot disable the Squelch Off function with the Ext.Monitor port.w/STEYou can configure the STE (Squelch TailEliminator) to be transmitted after transmittingthe QT/DQT code configured in theConventional Group channel using the PF Ext.PTT (Data) port. Normally, the STE istransmitted.External PTT(Voice) Configuration
