KP-4000 NETWORK KEYPAD IR OUT/RFTX-1 This 3 Conductor removable connector can be used for either an RFTX-1 RF transmitter or for a URC IR emitter. RFTX-1 Connections In installations with URC RF lighting or a standard RF base station, you will need to add an RFTX-1 RF Transmitter to the KP-4000. Range can wildly vary, depending on the structure of the wall the KP-4000 is installed in. You can make the RF range much more predictable by installing the RFTX-1 with the MRX-1 in most homes and this is the recommended method! However in some installations, you may achieve satisfactory results from an RFTX-1 inside the wall cavity. To connect use the following terminations to the KP4000: Data - Connect the white wire which is connected to the Tip of the 3.5mm plug GND - Connect the black wire which is connected to the bottom sleeve(base) of the 3.5mm plug 5V - Connect the red wire which is connected to the ring of the 3.5mm plug IR Emitter Connection Should you need to drive an IR emitter directly from the KP-4000, you connect the emitter to Data and GND. A URC emitter is wired with a cable that has a silver and a copper conductor. If you have another brand of emitter, reverse polarity if the first attempt doesn't work. URC emitters can be successfully powered over long cable lengths if the wire gauge is at least 16 gauge. Data - Silver Conductor GND - Copper Conductor Page 6
