The RKN4155 has been replaced by the HKKN4027A programming cable

The Motorola RKN4155 provides you with unheard of capabilities in managing your fleet of RDX Series two way radios. This cable, along with Motorola's RDX Software allow you to program your Motorola RDX Series two way radios using your computer. Programming software, a single unit charging tray, and the RKN4155 are required to program your RDX Series two way radios. Please note, this cable is required as a standard USB cable does not have the technology within it to communicate with your Motorola RDX Series two way radios.

Motorola RDX Series software can be found by visiting the Motorola Solutions website, finding the RDX Series and clicking on the resources tab. The RDX Series software tab can be found midway down the left side of the page.

The Motorola RKN4155 will program the following Motorola two way radios:

RDU2020, RDV2020, RDU2080D, RDV2080D, RDM2020, RDM2080D, RDU4100, RDU4160D, RDV5100, CP110
