We're not sure what you are talking about. You need no separate plug/connector in order to link the R6014HS receiver to your transmitter. Just turn on the transmitter, then turn on the receiver. Press the LInk button for more than 2 seconds. Actually, hold it down until the LED goes green. The only time you need a shorting plug in the data port is when you are using the MPDX-1 multiplexer unit.
