Software - Motorola Mototrbo Cps 20 Programming

Motorola MOTOTRBO CPS 20 Programming Software — Overview & Guide

The Programming Cable (RKN4105 or aftermarket)

You cannot program a MOTOTRBO radio with a standard USB printer cable. You need a specific USB programming cable (Motorola part #RKN4105) which has a built-in logic chip. Note: The cheaper $15 eBay cables work with CPS 20 about 70% of the time, but they often corrupt codeplug data. Always use a genuine cable for commercial fleets.

Error 1: "Codeplug Version Mismatch"

• Problem: The radio's firmware is newer/older than the CPS 20 version.
• Fix: You must either update the radio's firmware (using the CPS Firmware Update tool) or find an older version of CPS. Pro tip: Keep CPS 20 updated to the latest build number.

5. Basic Programming Steps

6. Writing the Codeplug to the Radio

1. Verify all settings.
2. Click Write → Write Device (or Ctrl+W).
3. Select COM port.
4. Confirm any warnings (e.g., firmware mismatch — avoid writing if warned unless you have matching firmware).
5. Wait for the progress bar to complete. Do not disconnect during writing.
6. After successful write, the radio will reboot automatically.

3. IP Site Connect (Roaming)

For wide-area coverage, CPS 20 configures roaming parameters. You can set up RSSI thresholds (Received Signal Strength Indication)—telling the radio exactly when to drop a weak repeater and scan for a stronger one. This is vital for campus security or warehouse logistics. motorola mototrbo cps 20 programming software
