Question about Sena SR10 Motorola Twin Pin Two-Way Radio Cable

1 Answer

SR 10, Sena Cable and CP200

The interface works up to a point. When I increase the volume on the radio above 30 percent the radio alternates between transmit and receive until the volume control is lowered. It occurs whether the SR 10 is powered or not. Has anyone else experienced this? I have double checked the radio programming and tried it with another SR 10. Any suggestion would be appreciated.

A few things come to mind: 1) Be certain the radio is turned off when plugging in the Sena SR10 cable. Plugging in an audio device when the radio is turned on can cause the radio to seem like it is in somewhat of a VOX mode, with the transmitter being open or partially open. 2) Be certain the plug is in all the way. You should feel a click when seated properly. 3) Be certain the Sena SR10 cable you are using is the one for the Motorola CP200. The rings on the 2.5mm and 3.5mm prongs differ between the Motorola cable and others.
Best regards.

    Thank you for the suggestions. The interface cable is the only one that SENA sells with the two pin connector. It shows that it is for use with the CP200. I have checked the cable with a DMM and the pinout is the same as their documentation. Has anyone else had success using a CP200?

My Cp200 can't connect to my new Motorola Talkabout T5720 (7 Channels) 2-Way Radio, need HELP

The CP200 is a dealer programmable radio which was available in UHF or VHF. You would need the UHF model to match. Then the radio itself would need programmed to the same frequencies as the T5720. This requires Motorola proprietary software, cable and radio interface box (RIB). Your best option would be stopping by your nearest dealer to have it programmed.

Cp200 squeel

This is called feedback. The audio output from the other radio is feeding back through your microphone. Turn the volume down on the radio at a comfortable listening level, and do not transmit when in close proximity. If they can hear you speak, you do not need to transmit.

Cannot adjust volume

You possibly have a bad volume pot (potentiometer), or it is possible you are mixing narrowband and wideband radios together, and the narrowband radio is whispering to the wideband.

The volume pot is something which would be replaced during a radio repair. (Current 2014 pricing is around $85).

Best regards.

Feb 17, 2014 | SR-10 Adpater Cable - Kenwood Twin-Pin...

1 Answer

Kenwood kax-38 amp. distorted sound from turnatable if connected to the phono rca plugs, but ok if connected to the CD rca plugs.

The phono sockets for this are at different line levels for that reason. Phone is for the turntable depending on the type. If it is a later model stereo and an older model cheaper turntable, it uses an older type of needle cartridge called ceramic. The signal output of it is higher than the later magnetic cartridges and may need a preamp (radio shack) to match the line level signal, allowing it to clear the distortion. If this scenario were reversed, using an older cheaper stereo with a later, better quality turntable, the opposite would happen. (signal to low) This preamp would amplify the input. I think you need what is called a matcher to lower the input signal instead of the preamp. I've seen these at radioshack. BTW, the CD input doesn't distort as much because a cd player puts out a high signal and the amp is matched to accept it.

No volume

There are two ways to turn up the volume.

First the mp3 player has the volume dial turn that up all the way

Second there is a volume knob on the dewalt radio it is the black knob on top of radio on the right.

If those two knobs are unsuccessful make sure radio is on AUX there is a button on front right above the two arrows on front of the radio push that button until it says AUX that might be the reason your not getting sound
