13 Internal Connector
45
However, the “Group - Channel” is not stored as the
Last 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 the
Last 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 and
Low logic levels.
With this function, you can control an internal option
board 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 a
QT/DQT is detected.
Note: If no QT/DQT is programmed for the channel
then carrier will cause the port to switch to a logic low
level, 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 Carrier
is detected.
You can use this terminal in the KDS-100 and
KGP-2A/2B.
The KDS-100 and KGP-2A/2B recognize the
transceiver’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 function
and the Emergency function.
The Horn Control logic changes when the transceiver
receives the DTMF or enters the 2nd Emergency
Mode.
(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 Emergency
function.
The Light Control logic changes when the transceiver
enters 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 the
transceiver is transmitting and High when it is
receiving.
You may use this terminal in the KDS-100 and
KGP-2A/2B.
The KDS-100 and KGP-2A/2B recognize the
transceiver’s status by checking this terminal’s
status.
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 combining
four codes: Scrambler Code 1 ~ Scrambler Code 4.
The operation of the TK-7100H/8100H has been
verified with the Transcrypt SC20-460.
The selected code is transmitted in Hexadecimal
from the terminal assigned to Scrambler Code1
(Output) ~ Scrambler Code 4 (Output).
