The Hemisphere S631 / S321+ / S321 External Radio Cable allows for the sending of corrections, and powering of the receiver to occur over the same cable. The three headed design means that everything you need is contained within the same cable. There is no need to use multiple cables to power the receiver and the base radio, everything is there on one cable.
The cable contains a 5 Pin power and correction cable, that allows for sending out corrections and receiving power through the same port. Unlike Hemisphere’s previous unit, the S320 which required two separate cables to power the unit, the S321 only requires one cable.
The cable also comes with a 5-Pin port that is compatible with both the Pacific Crest ADL radios and the Harxon Series of radios. With this cable there is always a solution for you.
Power is provided through the trailer plug, and is capable of powering both the external radio and the Hemisphere S631 receiver at the same time. There is no need for a separate power cable for the external radio.
