• 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.

The OEM CDM-1250 cable is a serial level cable that requires a RIB. Although you can find USB "RIBless" cables on eBay, these cables contain both a USB to serial level converter as well as a circuit board to emulate the RIB. It is much more complex than just attaching a connector to a USB cable.

If you already have a RIB you can make your own cable pretty easily using a 25pin serial connector, some modular cord, and an RJ-45 connector. The pinout is on Batlabs. If you don't already have a RIB you are likely better off just buying a "RIBless" cable off of eBay.

Ok James will deff do that, I had a USB cable for another radio I had and cracked it open to find the pin out on that and went ahead and crimped on a new 8pin RJ45 but that didnt work so I will go and do what you said.
