PAD – Radio-RRC:

At the Radio-RRC the PAD-jack 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 - these signals are also available

in the I/O-connector.

USB – Control-RRC:

A PC with straight-key functionality can be used to perform the keying, alone or in

combination with a CW-paddle. To activate keying the PC could use the DTR signal in the

virtual USB COM-port delivered by the RRC USB device. The PC control works in parallel with

the CW-paddle so it is possible to shift between PC-keying and the CW-paddle without

changing the configuration.

I/O-connector – Control-RRC:

A PC with straight-key functionality or other external keyer can be used to perform keying,

alone or in combination with a CW-paddle. To activate keying connect pin-4 (IN0) to GND.

The external keyer works in parallel with the CW-paddle so it is possible to shift between

external keying and the CW-paddle without changing the configuration.

Note - The straight-key input (IN0) is a generic input and cannot be connected direct to a PC,

you need an interface, see appendix.
