13 Internal Connector4213.2.2.3 COR Radio to PCCOR stands for Carrier Operated Relay.The transceiver transmits the COR commandevery time the received carrier status changes.• A carrier is found:STX + 2 (ASCII) + 1 (ASCII) + ETX• No carrier is found:STX + 2 (ASCII) + 0 (ASCII) + ETX PC to RadioNone13.2.2.4 TOR Radio to PCTOR stands for Tone Operated Relay.The transceiver transmits the TOR commandevery time the QT/DQT Decode status changes.The transceiver executes the same operation asthe COR when QT/DQT Decode is notprogrammed.• A QT/DQT is found:STX + 4 (ASCII) + 1 (ASCII) + ETX• No QT/DQT is found:STX + 4 (ASCII) + 0 (ASCII) + ETX PC to RadioNone13.2.2.5 TX Start Radio to PCThe transceiver transmits the TX Start commandwhen it enters the transmitting mode.STX + A (ASCII) + ETX PC to RadioThe transceiver transmits when it receives the TXStart command from the PC.STX + A (ASCII) + ETXNote: The transceiver transmits when it receives the TX Startcommand from the PC and it starts transmitting thecommand.13.2.2.6 TX End Radio to PCThe transceiver transmits the TX End commandwhen it enters the receiving mode.STX + C (ASCII) + ETX PC to RadioThe transceiver ends the transmission when itreceives the TX End command from the PC.STX + C (ASCII) + ETX13.2.2.7 DTMF Radio to PCThe transceiver transmits the DTMF commandwhen it decodes the DTMF signal.STX + I (ASCII) +DTMF Code (ASCII) + ETXThe DTMF Code consists of a maximum of 16digits. ExampleThe transceiver transmits the followingcommand when it decodes the DTMF signal“123”.STX + I (ASCII) + 1 (ASCII) + 2 (ASCII) + 3(ASCII) + ETXThis command is used for decoding the PTT IDusing the DTMF.The PC displays the transmitting party, usingthe DTMF command. PC to RadioThe transceiver transmits the DTMF Code whenit receives the DTMF command from the PC.The transceiver automatically stops thetransmission after it ends the DTMFtransmission.STX + I (ASCII) + DTMF Code (ASCII) + ETX13.2.2.8 Volume Radio to PCThe transceiver transmits the Volume commandevery time the volume level changes.STX + K (ASCII) + Level (Hex) + ETXThere are 32 volume levels: 00 (Hex) ~ 1F (Hex)(1F (Hex) = 31 (Dec)). PC to RadioThe transceiver changes the volume level when itreceives the volume command from the PC.STX + K (ASCII) + Level (Hex) + ETX
