Ports: Control; Ports: Foot Switch - microHAM micro2R u2R User Manual

The Control Port allows an application program (logger) that implements the microHAM Control (SO2R)
Protocol to operate micro2R completely with only a single USB connection. The microHAM SO2R Control
protocol allows a logger to specify Transmit Focus, Receive Focus, Stereo/Split headphone as well as
control antenna switching and optionally use the CW, FSK and voice memory functions.
When an application opens the control port, Router
reports port as open and displays settings used to
configure COM port.
Data flowing through the channel are indicated by two arrows. The green arrow indicates data flow from the
application to WinKey and the red arrow indicates data flow from WinKey to the host application.
Mon: Opens a "Control Protocol Monitor" window to capture microHAM SO2R Protocol communications
between a logger and Router. Controls for the monitor include Start, Stop, Clear and Save.
The Control Protocol Monitor should not be used under normal conditions. However, if there are
problems between a logger and Router, it may be useful to Start a capture and close the window.
When a problem is noticed, the window can be opened and the Control protocol log Saved for
analysis.
The monitor log is circular – only the last 20 kilobytes or so will be saved in order to prevent creating
very large files.
The monitor will display a description of each command from the application and the response from
Router. If a line ends in three dots (...) it means that the command or response has been broken
across two USB packets.
Router allows assigning a virtual serial port to the foot switch channel and selecting one of four available
input control lines (CTS, DCD, DSR or RING).
NOTE: CTS is not available if the foot switch channel is shared with the radio control port. The state
of the signal on the virtual port can be inverted by checking inverted box.
When a COM port is assigned for the foot switch but the application does not support foot switch status (or
no application is running), Router reports the channel as closed.
When an application opens the COM port (usually
at start-up), Router reports channel as open.
When the foot switch is pressed, this state is indicated by a red arrow.
