Motorola Cm140 Programming Software __link__ Jun 2026

A stable 13.8V DC power supply is required to power the mobile radio during the read/write process.

Plug your USB programming cable into the PC without connecting the radio.

If you are a hobbyist who bought a used CM140: You will need a good USB cable (use FTDI chips if possible, avoid Prolific), and you should learn how to use Compatibility Mode. Treat the software with respect—it works, but it bites if you make a mistake.

Check Device Manager to ensure your USB cable is assigned to a port between COM1 and COM4. Legacy Motorola software often cannot read ports higher than COM4. You can change the port number in the advanced properties of the driver. "Codeplug Version Not Supported"

The Motorola CM140 belongs to the Commercial Series (which includes the CM160, CM340, and CM360). It requires specific software and hardware versions to communicate effectively with a modern computer.

Create a scan list if you want the radio to scan through multiple channels. 5. Writing to the Radio

The hardware demands are modest by modern standards. The application itself takes up approximately 16 MB of free disk space, though you'll want more to save your radio's archive files, which are about 75 KB each. Processor and RAM requirements are minimal and align with the recommendations for the operating system you are using.

The Motorola CM140 operates in the 136–174 MHz (VHF) or 403–470 MHz (UHF) bands. Unlike modern trunking radios, the CM140 is a conventional analog FM radio. Its programming software is not a simple GUI but a low-level tool that writes directly to the radio’s EEPROM (typically an Xicor X24C16 or similar). The CPS communicates via a serial protocol at 9600 bps, 8 data bits, no parity, 1 stop bit.
