Open on your PC, locate your USB-to-Serial adapter, and manually assign it a COM port number between 1 and 4.
You need a cable with an RJ-45 connector on one end (to plug into the microphone jack of the GM950) and a serial (RS232) or USB connector on the other.
There are no newly developed official software releases from Motorola for this discontinued radio. When users search for "new" software, they are usually looking for the latest archived version that fixed previous bugs, or modified software installers that allow the program to run on newer 64-bit Windows operating systems. 🛠️ Hardware Requirements for Programming

To program the Motorola GM950, you cannot use modern windows tools directly. The software was built for vintage operating systems.
Follow this sequence strictly to avoid bricking your radio during data transfer. 1. Environment Preparation Boot your computer into native MS-DOS if using legacy RSS. If using a modern machine, launch an emulator like DOSBox.
Improved USB/Serial compatibility: Modern programming utilities increasingly support a broader range of USB-to-serial adapters and drivers, reducing the friction of connecting older radios to modern laptops that lack legacy serial ports. Open on your PC, locate your USB-to-Serial adapter,
Better profile and template management: Templates for regional channel plans, standard feature sets (emergency button behavior, voice announcements), and encryption presets can save time when provisioning replacement radios or scaling operations.
The Motorola GM950 was developed before the widespread adoption of modern Windows software. The tool used to program it is called . It's important to clarify that the GM950 never had a modern "Customer Programming Software (CPS)" in the way later Motorola radios do. The software you're looking for is legacy RSS, designed specifically for this platform.
For some versions of the RSS, you might need to run a virtualized Windows 3.1 environment inside DOSBox. Hardware Requirements: Cable and Interface When users search for "new" software, they are
Press the designated function key (typically then F2 ) to READ the radio data. Wait for the progress bar to hit 100%. 4. Modifying Frequencies
Legacy programming software strictly communicates via hardware serial ports. If your modern computer lacks a DB9 serial port, you must use a high-quality USB-to-Serial adapter. Adapters built with the FTDI chipset are highly recommended, as Prolific chipsets often fail to communicate with legacy RSS. Setting Up Your Programming Environment
For older radios like the GM950, modernization of the programming toolset can mean fewer manual steps, fewer service calls, and lower total cost of ownership. It’s not just convenience: for safety-and-mission-critical users, faster, less-error-prone configuration can materially improve response.
