Version: 1.11 Function Reference 14526 FUNCTION PORTNote:" The ARQ Mode is not available while the transceiver istransmitting with the Data PTT in Trunking system." 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.26.1.2 External PTT (Voice)External PTT (Voice) is the PTT port for voice channels.This port is used for the transmission request from aheadset or external microphone.The transceiver starts transmitting when the Ext. PTT(Voice) port becomes low.The transceiver ends transmission when the Ext. PTT(voice) port becomes high. If the CH/GID is the Data CH/GID when the port becomes high, the transceiver movesto the lowest Voice CH/GID in the current Zone andtransmits.You can configure the following functions to the Ext. PTT(Voice) port.Table 26-3 Ext. PTT (Voice) Port ConfigurationNote:" 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 also transmits the PTT ID if the PTT ID isconfigured to the CH/GID.26.1.3 External PTT (Data)The Data PTT is the PTT port for data communications.You can use the port as below.! Using the External PTT (Data) Port with DTCThe External PTT port is used for the transmissionrequest in ARQ Mode if it is used with the DTC.After activating the DTC, data is transmited byactivating the Ext. PTT (Data) port.! Using the External PTT (Data) Portwith CH/GID Select A-DThe External PTT port is used to request PTT for anexternal data communication device if it is usedwithout using the Direct Channel (DTC) function. Thetransceiver transmits on the current Data CH/GIDwithout moving to the Data Zone-CH/GID.The Ext. PTT (Data) port has priority when the DataOverride function is enabled. (Refer to 25.1.6 DataOverride.)The transceiver starts transmitting when the Ext. PTT(Data) port becomes low.The transceiver ends transmission when the Ext. PTT(Data) port becomes high. The transceiver does nottransmit if the current CH/GID is Voice CH/GID.You can configure the following functions to the Ext. PTT(Data) port.Table 26-4 Ext. PTT (Data) Port Configurationw/STEYou can configure the STE (Squelch TailEliminator) to be transmitted after transmittingthe QT/DQT code configured in theConventional Group channel using the DataPTT port. Normally, it is configured to transmitthe STE.External PTT(Voice) ConfigurationModulationLineYou can configure the modulation line for the PFExt. PTT (Voice) port. The following modulationlines are available.• Mic (the audio line of the Mic located on thefront of the transceiver)• MI2 Line (the audio modulation line of the D-sub connector located on the rear of thetransceiver)• DI Line (the data modulation line of the D-subconnector)The default modulation line is the MI2 line.w/QT/DQTYou can configure the QT/DQT for theConventional Group channel to be mixed whenthe transceiver transmits the code from the PFExt. PTT (Voice) port. Normally, the QT/DQT ismixed when it is modulated.w/STEYou can configure the STE (Squelch TailEliminator) to be transmitted after transmittingthe QT/DQT code for the Conventional Groupchannel using the PF Ext. PTT (Voice) port.Normally, it is configured to transmit the STE.Data PTT ConfigurationExternal PTT(Voice) ConfigurationModulationLineYou can configure the modulation line for theExt. PTT (Data) port. The following modulationlines are available.• Mic (the audio line of the Mic located on thefront of the transceiver)• MI2 Line (the audio modulation line of the D-sub connector located on the rear of thetransceiver)• DI Line (the data modulation line of the D-subconnector)The normal modulation line is the DI line.w/QT/DQTYou can configure the QT/DQT for theConventional Group channel to be mixed whenthe transceiver receives the code using the Ext.PTT (Data) port. Normally, the QT/DQT ismixed.
