• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I have two Motorola CM200's and trying to setup a repeater between both.
I have: https://www.amazon.com/Generic-gsd-Repeater-Interface-Motorola/dp/B01DD0XMQM/ref=sr_1_1?ie=UTF8&qid=1478021378&sr=8-1&keywords=pm400+repeater+cable

Can anyone please help me to know what to set within the program to get these to work? I tried setting pin 8 to PL/CSQ Talkgroup Detect with low and debounce but I do not see a Pin 2 or Pin 11. only pin3,4,6,8,9,12,14. I have the Accessory Package set to Default. Do I need to change this? I appreciate any and all help as I am new to this. Thanks

Edit: I am now able to get it to work but no audio is being carried.

Did you ohm out the leads to make sure you have continuity?
Can't tell from the amazon photo, might be a cap in there which would block the test.

While the cable is not for the way you intended, it can still be used. Just disable the PTT wire (pin3) to the receive radio. You can pull it out of the housing with a release tool or simply cut it. That will make the cable strictly uni-directional.

The only two programmable pins you need to concern yourself with is 3 and 8. Pin 3 should be set as "External Mic PTT", and pin 8 as "PL/CSQ/Talkgroup Detect". Both active low.

Also under accessories, Rx Audio Type needs to be set as "Filtered Audio" and External PTT Audio Source as "Ext Mic Audio"

Other than setting the level on the cable, this is all that needs to be done.
