Preparations of DX-SR8 for remote control (mode=12)
(updated 10-05-17)
 
All necessary signals between the panel and the radio is connected thru the 8 wire standard patch cable between the control panel and the radio. We just need to use two standard patch cables , one between the Control panel and the Control-RRC and the other one between the Radio-RRC and the radio. The following signals is represented in the cable. Convenient for travelling is that the speaker is already present on the back of the control panel so there is no need for a extra speaker even if a bigger separate speaker gives better audio.

8-pol Modular RJ45

1. TXD data from radio to control panel
2. RXD data from Control panel to radio
3. 8V power to control panel (when radio is switched on)
4. Not in use
5. Mic signal / PWR On/off button
6. GND
7. AF - Audio to speaker.
8. SPK GND- Speaker ground


Before connecting the cables to radio and control panel you need to do some strappings inside the RRC:s. For instructions of how to open the RRC:s see "Open the box / straps" page. Down below is the strappings that need to be done described.

Attention! Always check for updated drawings before starting to make cables

Cables control panel to RRC-1258MkII

No drawings needed only standard patch cables are used

The Control-RRC are powered with a simple 13.8V (10-18V) power supply. The display (backlighter) and speaker amplifier needs lot power so use min 1A.

 A switched 13,8V/1.5A FRIWO Power supply can be bought together with the RRC:s to a reasonable price.
