Motorola HKKN4027 Programming Cable

What is the HKKN4027?

The Motorola HKKN4027 (also sold as HKKN4027A) is a USB programming cable that connects compatible Motorola business two-way radios to a Windows PC, enabling radio configuration through Motorola's free Customer Programming Software (CPS). It is compatible with the CLS, CLP, CLPe, DLR, DTR600, DTR700, RDX, and RM series of Motorola business radios, as well as the Motorola Curve. Its primary function is to allow administrators to customize radio settings—including channels, scan lists, radio IDs, and power output—without sending units to a service center.

Specifications

Note on software version: If upgrading to CLP Series CPS Version 2.0, the prior version must be uninstalled before installing the new version. Always download CPS from Motorola Solutions to ensure version compatibility with your specific radio model.

What's in the Box

• 1 × Motorola HKKN4027 USB Programming Cable

Programming software is not included in the box. The Motorola Business Radio CPS is a free download from Motorola Solutions and must be installed on a Windows PC before the cable can be used to program radios.

Who This Product Is For

The HKKN4027 is used by organizations that manage a fleet of Motorola business radios and need to configure multiple units to the same operational parameters, or to make individualized adjustments to specific radios. It is not a cable a single end-user typically needs; it is a tool for radio administrators, IT coordinators, and fleet managers.

Common use cases and industries include:

• Hospitality: Hotels and resorts with CLP or CLPe radios frequently program units with department-specific channel plans and restrict unauthorized frequency changes. The HKKN4027 enables in-house reprogramming when staff assignments change.
• Retail and warehousing: Operations using RDX or RM series radios may need to add or remove channels when store layouts change, or when coordinating with temporary workers during peak seasons.
• Healthcare facilities: Organizations deploying CLP or CLPe radios in clinical environments can use the cable to lock radios to designated channels and disable features not needed for their workflow.
• Education: Schools and universities managing DTR600/700 or DLR series radios across buildings or campuses use the HKKN4027 to assign unique radio IDs and configure call lists without sending units off-site.
• Manufacturing and industrial: Facilities with RDX or RM series radios benefit from being able to add channels for new operational zones or shift structures without third-party service delays.
• Security and events: Security teams and event production crews using CLS or DLR series radios often need rapid redeployment with updated channel programming between events or shifts.

Any organization that purchased radios requiring dealer programming at time of sale can use this cable to bring that capability in-house, reducing turnaround time and service costs for ongoing configuration changes.

Key Features

• Connects a compatible Motorola business radio directly to a standard USB port on a Windows PC
• Used in conjunction with Motorola's free Business Radio CPS software to read and write radio configurations
• Allows configuration of channels, scan lists, radio IDs, power settings, and other programmable parameters depending on the radio model
• Replaces two earlier Motorola programming cables: the RKN4155 (used for RDX series) and the HKKN4025 (used for CLP series) — one cable now covers both radio families and additional series
• Genuine OEM Motorola accessory, not a third-party or aftermarket cable
• Required for any radio that was originally configured by a dealer and needs updated programming in the field
• Windows PC only — macOS is not supported by Motorola's CPS software for these radio families
• One cable can be used to program any number of compatible radios sequentially

Frequently Asked Questions

What does the Motorola HKKN4027 programming cable do?

The HKKN4027 is a USB cable that physically connects a compatible Motorola business two-way radio to a Windows PC. When used with Motorola's free Customer Programming Software (CPS), it allows a radio administrator to read the radio's current configuration and write a new one. Programmable settings vary by radio model but typically include channels and frequencies, scan lists, radio IDs and names, transmit power levels, and which features are enabled or locked out on the radio's controls.

Does the HKKN4027 work with Mac computers?

No. Motorola's Customer Programming Software (CPS) for the radio families compatible with the HKKN4027 runs on Windows only. The cable itself is a standard USB device, but without CPS the cable has no function. If your organization uses macOS exclusively, you would need a Windows machine or a Windows virtual machine environment to run CPS. Motorola does not currently publish a macOS version of CPS for these business radio series.

Is the CPS software included with the HKKN4027?

No. The cable ships alone. Motorola's Customer Programming Software is a free download available directly from Motorola Solutions. You will need to download the correct version of CPS for your specific radio model — different radio series (CLS, RDX, DLR, DTR, RM, CLP) each have their own CPS version. Installing the wrong version will not allow you to program the radio. If you are upgrading CPS for the CLP series to Version 2.0, Motorola requires that the previous version be fully uninstalled before installing the new version.

What is the difference between the HKKN4027 and the HKKN4027A?

The HKKN4027 and HKKN4027A are the same product. The "A" designation is a minor revision suffix used in Motorola's internal part numbering. Both versions are functionally identical and are interchangeable. You may see either part number listed at retailers; both will work with the same compatible radio models. This cable also replaces two earlier Motorola programming cables: the RKN4155 (previously used for RDX series radios) and the HKKN4025 (previously used for CLP series radios).

Can one HKKN4027 cable be used to program multiple radios?

Yes. A single HKKN4027 cable can be used to program any number of compatible radios, one at a time. The cable connects to the radio's accessory port for each programming session, and the connection is released when the cable is unplugged. There is no pairing or licensing restriction that limits the cable to a single radio. Organizations that manage large fleets typically keep one cable on hand and connect each radio sequentially when reprogramming is needed.

Do I need the HKKN4027 to use my Motorola radio out of the box?

Not necessarily. Motorola business radios come from the factory with a default configuration, and many organizations use the radios with those default settings. The HKKN4027 is only required when you want to change the factory configuration — for example, to program specific UHF or VHF frequencies on licensed radios, to restrict the channel range available to users, to assign unique radio IDs, or to align a new radio to match the channel plan of an existing fleet. If your radios were originally programmed by a dealer and you need to update those settings yourself, this cable is what makes that possible.

Is the HKKN4027 compatible with the Motorola Curve?

Yes. The Motorola Curve is listed as a compatible radio for the HKKN4027 by Tech Wholesale and other authorized Motorola dealers. The Curve replaced the DLR series, and the HKKN4027 carries forward compatibility with that radio family. As with all Curve programming, the appropriate CPS version for the Curve must be used — verify the correct software version on the Motorola Solutions support site before attempting to program.
