Audio out of XTS 2500 Portable.

[Dygear]

I have an XTS 2500 provided by my local police department. I'd like to get audio out of that to a 3.5mm audio connector to send the audio throughout my station. It seems that the BDN6676D connector is what I want, but it says it's a threaded 3.5mm connector. I would need a threaded 3.5mm to plain 3.5mm connector. Or is there another method that I should be using that I'm not seeing?

Your probably going to end up with having to use a speaker mic cable to obtain the audio out of the XTS2500. But I believe that once you put that connector onto the side of the portable, it will mute the internal speaker.

Pin 2 on the accessory connector is RX audio high. Pin 20 is RX audio low. Pin 13 and 15 are ground.

Depending on who made the cable, the wire colors will be different.

Do you have a recommendation on speaker mic, perhaps a part number?

The XTS 2500 only has 13 pins for the accessory port.

You *could* use the BDN6676D assuming you wired the cable coming out of the 3.5mm jack appropriately.

IIRC (its been a minute since I had to wire one of these dongles); you don't want to ground the tip to the sleeve as that causes the BDN6676D to key the radio allowing mic audio to flow over the ring. To get audio out of that you would need a threaded 3.5mm plug; you leave ring floating and a DC blocking capacitor and a resistor between the tip on the 3.5mm and the audio device. Attach audio device ground to the sleeve on the 3.5mm.

Putting the audio device direct in between the tip to the sleeve without the DC blocking cap or resistor will cause the radio to key.

Is there a commercial cable that I can buy that will do this for me? I'd prefer not too hack this solution too much.
