Both Kenwood and Yaesu transceivers need the RTS and CTS pins to be strapped together.
JMP-3 inside the box can be used to strap them if you want to use a standard fully connected
cable.
PAD Control-RRC
At the Control-RRC the input is used to connect a CW-paddle. The input is for a standard 3.5
mm stereo plug. Normally the left paddle is connected to the tip and the right paddle to the
ring. Common is connected to the inner ring and ground. Note that the CW-Keyer function
must be enabled to activate this function.
PAD Radio-RRC
At the Radio-RRC the output is used to connect the output signal from the CW-keyer to the
radio straight KEY input. The output is for a standard 3.5 mm stereo plug. A standard cable
with 3.5 mm connector in both ends can often be used. Note that the OUT1 mode or OUT2
mode must be set to Keyer to activate this function.
