TTL Radio-RRC

The TTL connector on Radio-RRC (RJ-12) is used for connection of the cable which is normally

connected between the control panel and the radio (TS-480, RC-2000, and IC-2820). It's also

used for CAT control of radios with 5V.s inputs e.g. all ICOM with 3.5mm C-IV connector and

FT-8x7 with the mini DIN-connector. The connector is configured so a straight cable can be

used to a TS-480 control panel and to RC-2000.

SP Control-RRC

At the Control-RRC the connector is used as a speaker output. It's connected in parallel with

the audio output pins in the MIC/AUX and TTL connectors. The connector is a standard 3.5

mm jack for a mini stereo plug and there is no switch in the connector. The speaker output

power is 2W at 8 ohm. In the dual RX (stereo) version there are signals from both the Main-

RX and Sub-RX available in the SP-connector. There is only a Lf power amplifier on the Main

RX signal so I recommend that you set jumper JMP-4 in the Headset position and use headset
