So2R Tab - microHAM micro2R u2R User Manual

The SO2R Tab is used to configure the signals each program uses to convey Transmit Focus, Receive
Focus and Stereo (Split) headphone states to micro2R.
Computer AUTO Control:
If micro2R is in AUTO TX Focus and AUTO RX Focus, radio selection is under software control. micro2R
provides three ways for the application to control focus: "Classic auto control" (CT/NA compatible) using
the parallel (LPT) port, DTR and RTS signals on one or more serial port, or by software command
(microHAM Control Protocol).
NOTE: Software developers who would like to implement control of microHAM products including
micro2R using microHAM Control Protocol should contact
CLASSIC AUTO CONTROL is flexible tool for customizing micro2R for operation with legacy software.
There are four (4) parameters which can be controlled via parallel port (CT/NA compatible LPT) or virtual
serial port DTR and RTS signals.
TX focus: Used for automatic selection of the transmitter.
Available signals are:
LPT pin 3

Each signal can be inverted if necessary. The state of the signal is represented by a RED arrow.

receive.
Available signals are:
LPT pin 4
●
COM port RTS signal
●
COM port DTR signal
