13 Internal Connector45However, the “Group - Channel” is not stored as theLast Selected Channel.13.2.13 G1-CH4 Direct (Input)You may assign this input terminal to one of Port 1 ~Port 8.The transceiver moves to “Group 1 - Channel 4”when the port becomes a Low logic level.However, the “Group - Channel” is not stored as theLast Selected Channel.13.2.14 AUX (Output)You may assign this output terminal to one of Port 1 ~Port 8.The AUX key allows you to toggle between High andLow logic levels.With this function, you can control an internal optionboard or external devices using the transceiver keys.13.2.15 Tone Operated Relay(Output)You may assign this output terminal to one of Port 1 ~Port 8.The port switches to a Low logic level when aQT/DQT is detected.Note: If no QT/DQT is programmed for the channelthen carrier will cause the port to switch to a logic lowlevel, i.e. COR function.13.2.16 Carrier Operated Relay(Output)You may assign this output terminal to one of Port 1 ~Port 8.The port switches to a Low logic level when a Carrieris detected.You can use this terminal in the KDS-100 andKGP-2A/2B.The KDS-100 and KGP-2A/2B recognize thetransceiver’s status by checking the terminal’s status.13.2.17 Horn Control (Output)You may assign this output terminal to one of Port 1 ~Port 8.You may use this terminal for the Horn Alert functionand the Emergency function.The Horn Control logic changes when the transceiverreceives the DTMF or enters the 2nd EmergencyMode.(See APPENDIX –A in detail.)13.2.18 Light Control (Output)You may assign this output terminal to one of Port 1 ~Port 8.You may use this terminal for the Emergencyfunction.The Light Control logic changes when the transceiverenters the 2nd Emergency Mode.(See APPENDIX –A in detail.)13.2.19 TX Relay (Output)You may assign this output terminal to one of Port 1 ~Port 8.The TX Relay logic is a Low logic level when thetransceiver is transmitting and High when it isreceiving.You may use this terminal in the KDS-100 andKGP-2A/2B.The KDS-100 and KGP-2A/2B recognize thetransceiver’s status by checking this terminal’sstatus.13.2.20 Scrambler Code (Output)You may assign this output terminal to one of Port 1 ~Port 8.You may program the Scrambler code by combiningfour codes: Scrambler Code 1 ~ Scrambler Code 4.The operation of the TK-7100H/8100H has beenverified with the Transcrypt SC20-460.The selected code is transmitted in Hexadecimalfrom the terminal assigned to Scrambler Code1(Output) ~ Scrambler Code 4 (Output).Scrambler Code # (Output)CodeCode 1 Code 2 Code 3 Code 41 0 0 0 02 1 0 0 03 0 1 0 04 1 1 0 05 0 0 1 06 1 0 1 0
