Use the software to match the exact bandwidth configurations (Narrowband 12.5 kHz vs. Wideband 25 kHz) required by your licensing terms.
CPS is the Windows-based successor to RSS, used for newer radio models. For the GP series, the required software is almost certainly a version of . The exact part number and version depend on the specific radio model. For instance, the software for the GP380 has the part number ENLN4115 . Motorola Gp 868 Programming Software
Open the software and select "Read Radio" to import the current configuration from the device.
The radio will typically emit a chirp or restart itself automatically. Turn off the radio, disconnect the cable, and test communication with another unit. Troubleshooting Common Software Errors Probable Cause Actionable Solution Wrong COM port selected or driver failure.

Click on the icon on the top toolbar (or navigate to Device -> Read ). Wait for the progress bar to finish.
Do not plug the cable into the computer yet. Install the FTDI or Prolific driver executable first. Once installed, connect the programming cable to a USB port. Open Windows and expand the Ports (COM & LPT) section to verify that a "USB Serial Port" has been assigned a specific COM port number (e.g., COM3). Step 2: Install the Motorola CPS
Because the GP 868 belongs to Motorola’s older analogue Professional Series, it almost certainly requires a DOS‑based RSS designed for the GP300/GP350/GP88 family. Some users have successfully used a modified version of the GP300 RSS (sometimes identified as “MR7”) on similar radios. The more recent MOTOTRBO CPS2 is not compatible—that software is intended for Motorola’s digital DMR radios (e.g., the XIR P3688, P8668, and MOTOTRBO series). Wideband 25 kHz) required by your licensing terms
The programming software for the GP 868 reflects this heritage. Unlike the software for high-tier Motorola APX or XPR series (which can be overwhelming with thousands of parameters), the GP 868 software strikes a balance. It is robust enough to handle complex digital-analog hybrid settings but streamlined enough that a facility manager with some technical know-how can navigate it without a certification course.
