Ports: Control; Ports: Cw And Ptt From Lpt (Parallel Port); Ports: Generate Fs On Lpt - microHAM MK2R Manual

The Control Port allows an application program (logger) that implements the microHAM Control (SO2R)
Protocol to operate MK2R/MK2R+ 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, WinKey
2, (usually at start-up), 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.
MK2R includes an LPT interface for "CT/NA compatible" CW and PTT inputs.
When the "Use LPT for CW" box is checked, MK2R will accept CW input on pin
16 of the LPT input. The red arrow indicates when LPT CW is active (key down).
When the "Use LPT for PTT" box is checked, MK2R will accept PTT input from
pin 17 of the LPT. The red arrow indicates when LPT PTT input is active.
NOTE: Never enable more than one CW source at a time. You must select which source (WinKey, Serial
or LPT CW) will be used by MK2R. Selecting multiple sources will result in distorted CW output.
TIP: If you plan to use MK2R with DOS based software, check both Use LPT for CW and Use LPT
for PTT and select "Device | Store as Power-up Settings" from the Router menu.
When used with an LPT interface if the application supports it, MK2R can forward
the state of FS1 on Pin 15 of the LPT.
