Configure global settings such as time-out timer (TOT), squelch levels, and power-on text displays. Frequency/Channel Configuration (F5): Input Rx (Receive) and Tx (Transmit) frequencies.

Connect the cable to the PC and the radio's microphone jack. Turn on the radio.
The original Motorola GM950 programming software was developed for or Windows 95/98 . It relies on precise CPU clock timings to communicate with the radio.
Navigate to the main menu and select (often assigned to a function key like F3 or F4 depending on the version). Wait for the progress bar to complete. Motorola Gm950 Programming Software
The Motorola GM950 is a mobile two-way radio that was popular among businesses, public safety agencies, and other organizations. To program the radio, you'll need the appropriate software and a programming cable.
Enter your desired Rx (Receive) and Tx (Transmit) frequencies.
Insert the RJ45 connector of the programming cable into the microphone jack on the front of the radio. Connect the other end (Serial DB9 or USB) to your computer. Turn on the radio first, then power on your PC. Step 2: Configure the Software Environment If you are using a modern PC with DOSBox:
As the software was designed for now-obsolete operating systems, running it is the primary challenge for modern users. Here are the most common solutions. Configure global settings such as time-out timer (TOT),
The programming software allows you to:
The software guided John through the programming process. He was able to configure the radio's frequencies, set up the tone squelch, and even program the radio's keypad. The software was user-friendly, and John was able to complete the programming process in no time.
If you must use USB, choose an adapter with an FTDI or CP2102 chipset. Cheap Prolific chipsets often corrupt the data stream and can brick the radio. Step-by-Step Programming Process Step 1: Prepare the Environment
Note: Ensure you are using the correct version of the software tailored to your specific GM950 model (e.g., GM950, GM950 Plus, GM950E) to avoid codeplug corruption. 2. Setting Up Your Programming Environment (Windows 10/11) Hardware and Software Requirements How to Program the
To successfully program a Motorola GM950, you will need a specific combination of hardware and software tools. 1. The Software
Select either 12.5 kHz (Narrowband) or 25 kHz (Wideband). Note: Ensure compliance with local regulatory bodies regarding bandwidth limits. Step 3: Customize Radio Features and Buttons
For users comfortable with a command-line environment, , an open-source DOS emulator, can be used. One hobbyist guide describes setting up DOSBox, installing Windows 3.1 within it, and then installing the GM950 software. This requires careful configuration of the DOSBox configuration file, including setting the correct CPU speed to avoid timing issues ( core=normal , cputype=pentium_slow , cycles=fixed 2500 ) and mapping a physical or virtual serial port ( serial1=directserial realport:COM1 ).
