What cable you use is entirely dependant on the design of the control. I suspect that the MRC unit can use a telephone cord because the the hand held unit may not be transmitting full track power to the rails. It may just be sending a signal to the main control unit and that then interprets the signal to send power to the rails. If you are trying to send more than milliamps through the cable, you will need something bigger than phone cable and plugs.
