Motorola Gm950 Programming Software Install !!top!! »

The Motorola GM950 is a legacy radio that requires Radio Service Software (RSS) originally designed for DOS or Windows 3.1. Because modern operating systems (Windows 10/11) cannot run this software natively, you must use an emulator like DOSBox. 1. Hardware Requirements

Before installing, ensure you have the following specialized hardware:

Radio Interface Box (RIB): A hardware level shifter that allows communication between the computer and the radio.

Programming Cable: A RIB-to-radio cable specific to the GM950 model (typically connecting via the microphone port).

Computer: An older PC with a physical COM port is ideal. If using a modern PC, a high-quality USB-to-Serial adapter is required, though timing issues can occur. 2. Software Preparation You will need to source or set up the following software:

GM950 RSS: The specific programming software for this model (often found as wgm950 or similar archives). motorola gm950 programming software install

DOSBox: To emulate the legacy environment on modern Windows.

Windows 3.1/3.11: Some users prefer running the software within a Windows 3.1 environment inside DOSBox for better stability. 3. Installation Steps for Modern Windows (via DOSBox)

Follow these steps to set up the programming environment on a modern PC:

Configure DOSBox: Modify the dosbox.conf file to match the slow timing of legacy hardware. Set the [cpu] section to core=normal, cputype=pentium_slow, and cycles=fixed 2500.

Map Serial Ports: In the [serial] section of the config, map your physical COM port to DOSBox: serial1=directserial realport:COM1. The Motorola GM950 is a legacy radio that

Prepare Installation Files: If your RSS is in folders like disc1 and disc2, copy all files from both into a single working directory (e.g., C:\motorola\gm950). Mount and Run:

In DOSBox, mount your working directory: MOUNT C C:\motorola\gm950.

Navigate to the drive and run setup.exe or the main software executable (often gm950.exe).

If using Windows 3.1 inside DOSBox, launch Windows first, then use File -> Run to execute a:\setup.exe where a: is mounted to your RSS folder. 4. Basic Programming Workflow

Once installed, follow these steps to interact with the radio: Best Practices

Connection: Power on the radio and connect it to the RIB, then connect the RIB to the PC.

Read Radio: Click the "Read" button in the software to pull the current configuration (serial number, frequencies, power levels) from the radio.

Modify & Write: Adjust your frequencies or settings as needed, then use the "Write" function to send the new configuration back to the radio.

For further hardware details, the Motorola GM950 Service Manual provides technical specifications on frequency ranges and power supply requirements. Programming the Motorola GM950 on Windows 10

Installing the CPS. Ok, let's get the last part done. If you downloaded the Motorola RSS you will find two folders in the archive. Programming the Motorola GM950 on Windows 10

Important Note Before You Start:
The official software for the GM950 is called Motorola Radio Service Software (RSS) or CPS (Customer Programming Software) , depending on the version. This software is DOS-based (even the Windows versions run in a DOS box). It will not run directly on 64-bit versions of Windows 7, 8, 10, or 11. You will need a 32-bit OS or a DOS emulator (like DOSBox).

Best Practices

5. First Launch & Port Configuration

  1. Open GM950 CPS.
  2. Go to File → Preferences (or Communications menu).
  3. Select the correct COM port (matching your adapter).
  4. Set:
    • Baud rate: 9600 (default)
    • Parity: None
    • Data bits: 8
    • Stop bits: 1
  5. Click OK.

9. Important Legal & Safety Note

Programming the GM950 with unauthorised frequencies (e.g., out of band, public safety channels without licence) violates FCC/Ofcom/IC regulations. Always ensure you have a valid amateur or commercial licence for the frequencies you program.
