Kenwood in general

RRC-1258MkII also supports the Kenwood protocol used by almost every Kenwood radio. You need to use a PC-software ex. HamRadioDeLuxe or a similar rig control software at the control site. All audio and data communication goes true the RRC:s so you don’t have to worry about the audio quality. No more problems with soundcards and Skype etc. And most important, you don’t need a PC at the remote site.

(updated 10-05-11)

When you want to control Kenwood radios with the RRC-1258MkII via the Kenwood CAT protocol, you connect a standard RS-232 cable between the PC and the COM 2 connector on the back of the Control-RRC. From the Radio-RRC:s COM2 connector to the radios CAT connector( D-sub RS-232) you use a special RS-232 cable  ( see drawings ). They are also “off the shelf” cables also but not as common as the straight cable.

The microphone can be connected direct to the Control-RRC AUX/MIC jack, if you have a mic with RJ-45 connector. If you have a microphone with a circular connector you can buy a adapter cable MJ-88 from Kenwood, from our webshop or make one by your self.

Between the Radio-RRC AUX/MIC jack and the radios microphone jack you can connect a standard patch cable if the radio have a RJ-45 jack. If the radio have a circular microphone jack you need to make a adapter cable by your self or buy one from our webshop. If you make the cable by your self make it short as possible to prevent it from picking up HF.

The speaker is connected direct to the SP-jack on the front of the Control-RRC with a 3.5 mm stereo plugg.

The speaker signal from the Radios ext. speaker jack to the Radio-RRC SP jack is connected via a standard “off the shelf cable” with 3.5 mm stereo plugs in both ends.

Attention! Always check the users manaul for updated drawings before starting to make cables

Strapping

Before connecting the cables to radio and control panel you need to do some strappings inside the RRC:s. For instructions of how to open the RRC:s see “Open the box / straps” page. Down below is the strappings that need to be done described.

If you  want to be able to Connect resp. Disconnect the SIP-connection via the Microphone UP button you can add the grey strap in the control RRC. But don’t press the button when you are in QSO.
