: This version introduced official support for the CM340 and CM360 radios, making it the baseline for programming these models. It also restructured the software interface by moving the channel position setting from "Conventional Personalities" to a new "Channel Position" menu item.
The Commercial Series CPS was originally designed during the Windows XP and Windows 7 eras. Making it work on modern operating systems like Windows 10 or Windows 11 requires specific adjustments.
The software "works" to define complex scan lists. You can set up:
Once the software is open and communicating with the radio, the process is straightforward: motorola cm340 programming software work
Once edits are complete, click the icon (or press Ctrl + W). Keep your hands off the computer and cable during this process. The radio will display processing indicators or emit a tone, followed by a reboot chirping sound indicating a successful write. 5.

You need a (e.g., KN400A or a clone). Do not buy a $5 USB cable from a random seller. You need one with a genuine FTDI chip for USB-to-serial conversion.
Change the port to an unused number between and COM4 . If all are marked "in use," you can safely override an older, disconnected device.

The software will pull the "codeplug" (configuration file) from the radio's EEPROM memory. Step 4: Modifying the Codeplug
: A specialized programming cable connects the radio's accessory port (or microphone port) to the computer's serial or USB port.
Getting your Motorola CM340 mobile radio to communicate with your computer requires the right software, hardware, and configuration. This commercial-grade UHF/VHF radio relies on specific legacy software environments.
USB programming cables with built-in FTDI chips are highly recommended for driver stability on modern PCs. 3. How the Programming Process Works The Commercial Series CPS was originally designed during
The Motorola CM340 is a rugged, reliable mobile two-way radio widely used in commercial and industrial environments. To customize channels, power levels, signaling protocols, and button functions, you must use the correct Motorola Commercial Series Customer Programming Software (CPS). Getting the software to work correctly requires navigating specific operating system compatibility rules, choosing the right hardware interface, and configuring communication ports. The Required Software
DOSBox is an emulator originally designed for gaming, but it works remarkably well for legacy radio software.
The programming software (often called CPS – Customer Programming Software) does not simply transfer files like a USB stick. It sends a specific voltage and data timing protocol. The CM340’s microprocessor listens for a "handshake" signal on its side connector. If the handshake fails, the radio will display "Device not responding" or simply turn on as if nothing happened.
