Software alone will not allow you to communicate with your radio. You need a complete programming kit to link your PC to the HT1250.
The HT1250 has a specific accessory jack on the side. Ensure your programming connector has the "notch" required to fit deep into the radio’s port. A generic RIB cable meant for a Maxtrac or Spectra will not physically fit without modification.
Connect the programming cable to your PC and the side connector of the HT1250. Turn on the radio and set the volume to a medium level. Open the Professional Radio CPS software.

The HT1250 must operate on a sufficiently charged battery or a dummy battery connected to a 7.5V DC supply. Low voltage during programming can cause a fatal codeplug checksum error, potentially bricking the radio.
This software is designed for older Windows operating systems, typically Windows XP or Windows 7. Running it on Windows 10 or 11 can be difficult and may require compatibility modes. 2. The Hardware: Programming Cable
Input your VHF (136-174 MHz) or UHF frequencies. PL/DPL (CTCSS/DCS): Set your receive and transmit codes.
Programming two-way radios involves legal responsibilities. In the United States, the FCC mandates that programmable radios operate only on authorized frequencies under a valid license (e.g., business, public safety, amateur). It is illegal for an unlicensed individual to program frequencies not covered by their station authorization. Furthermore, Motorola holds copyright on CPS software; distributing or downloading it from unauthorized sources violates the Digital Millennium Copyright Act (DMCA) and EULA agreements. Most ethical programming is performed by certified radio technicians or directly by licensed entities that purchase the software from Motorola or its dealers. Software alone will not allow you to communicate
Check your Device Manager to ensure your USB-to-Serial driver is correctly installed and assigned to a low COM port number (ideally COM1 through COM4).
With the codeplug loaded, you can now configure the radio. The software is well-organized with tabs for different functions:
The radio will beep and restart once the write process is successfully completed. Summary Checklist for Success Requirement Motorola Professional Series CPS (Preferably R06.12.05) Cable Chipset FTDI Chipset (Avoid generic Prolific chips) PC Settings
The HT1250 uses a unique multi-pin accessory connector on the side of the radio. You will need an HT1250-specific programming cable. Ensure your programming connector has the "notch" required
Create scan lists so the radio automatically cycles through selected channels to listen for activity. Step 5: Write Data to the Radio
Ensure you hold a valid FCC license (GMRS, Business, or Amateur Radio) for any frequency you program into the device to transmit.
Connect the programmed cable between the PC and radio. Turn on the radio.
