The "RIB-less" Cable Controversy

Older Motorola radios required a massive "RIB" (Radio Interface Box) plus a serial cable. However, the GM950 (especially the Plus model) is often "RIB-less" compatible. You need a specific USB-to-16-pin cable where the logic level conversion is built into the cable’s dongle.

Recommended setup:

• Cable Type: USB to 16-pin Molex (Kenwood-style 2-pin audio is NOT compatible).
• Chipset: FTDI (Prolific clones often cause Blue Screens of Death on Windows 10/11).
• Voltage: The GM950 uses 5V TTL logic. Do not use a straight RS-232 cable without a RIB.

System Requirements

Because this software was written for Windows 95/98 and DOS, you are going to have a hard time running it on a modern Windows 10 or 11 machine. Software Name: Motorola GM950 Programming Software ( CPS 2

• Speed: The software is timing-sensitive. Running it on a modern multi-core processor can result in communication errors.
• Solution: Most technicians keep an old Windows XP or Windows 98 laptop solely for programming these legacy radios. Alternatively, you can run it in a virtual machine (like DOSBox) with proper serial port passthrough.

Where to Find the Software Link

Because of copyright and licensing restrictions, no direct download link can be provided here. However, legitimate ways to obtain the software include:

1. Authorized Motorola Dealers – They can program the radio for a fee or, in some cases, sell you the software kit (part number: RVN4191 for GM950 RSS).
2. Motorola Solutions Resource Center – Existing service partners can log into MOL and search for “GM950 RSS.”
3. Archival / Hobbyist Communities – Some radio forums (e.g., Batlabs, RepeaterBuilder) discuss the software, but downloading from unofficial sources carries legal and malware risks.

Common Errors & Troubleshooting

If you have the software link but it won't work, check for these:

• "Communication Timeout": Your COM port is wrong, or your USB driver is not installed. Try COM 1, 2, 3, or 4.
• "Codeplug Too New/Too Old": You are using the wrong software version (Standard vs. Plus). Or, the radio was last programmed with a newer version of CPS than you have.
• "Invalid Frequency": The GM950 is band-specific (VHF: 136-174 MHz; UHF: 403-470 MHz or 450-520 MHz). You cannot program a 450 MHz radio to receive 146 MHz.
• Blue Screen when connecting: You are using a Prolific USB-to-serial clone. Buy an FTDI cable.

Date: Current

Important Legal & Technical Notes

• Copyright Law: Distributing or downloading Motorola RSS without authorization violates Motorola’s copyright. Use at your own risk.
• Radio Programming Mistakes: Incorrect settings (e.g., wrong frequency band, misaligned squelch) can render the radio non-compliant with FCC/IC regulations or even brick the device. Back up the original codeplug first.
• Modern Alternatives: If you only need to change a few settings, consider hiring a two-way radio shop – it's often cheaper and safer than chasing outdated software.

Computer Requirements

• For DOS RSS: You need a true serial port (COM1/COM2) or a very good USB-to-serial adapter. You will also need DOSBox or an old laptop running Windows 98/XP.
• For Windows CPS: Windows XP is ideal. Windows 10/11 32-bit might work, but 64-bit versions almost always fail due to driver signature requirements.
