application running on a PC. When ESC-W is entered, the K45 operating system will be temporarily
disabled, and the host USB port will be directly connected to the WK3 IC. The K45 will then operate exactly
like a WKUSB or WKmini would in host mode.
Before connecting the K45 to a PC's USB port, a CH340 USB driver must be installed, refer to
appendix D on page 38.
In WinKeyer mode, the rotary encoder will function in a similar way to a normal WKUSB speed pot without
physical end stops like there are on a potentiometer. The host application's speed pot min and max settings
determine what the end stops will be.
Just like WKUSB, the K45 will appear as a serial com port to a host application. Here are the steps to follow
to run K45 from a host application.
1)
K45 must first be plugged into one of the PC's USB ports.
2)
Enter ESC-W on the K45 to start WinKeyer Mode.
3)
Determine the USB com port using Device Manager or WKscan on the PC.
4)
The USB com port address is then entered into the application's WinKeyer setup dialog box.
5)
When WinKeyer mode is started on the K45, a Port Closed status is displayed. This status will
change to Port Opened when a host application is started and it connected to the K45.
6)
When the application is shut down it disconnects from the K45 and the status message changes
back again to Port Closed.
Some things to know about K45 WinKeyer mode
1)
Unlike WKUSB, the K45 does not have any message pushbuttons.
2)
There is no WKUSB standalone mode, please don't modify settings with WK3tools.
3)
Upon entering WinKeyer mode, the K45's keyboard (if attached) is disabled and not used.
4)
Like WKmini, the K45 provides two keying ports without PTT or one port with PTT.
5)
The K45 encoder emulates a WKUSB speed pot as close as possible. It generates one WPM
change per click. If you turn the pot extremely fast, the K45 may miss a step.
6)
The K45 must be in WinKeyer mode before a USB comport will show up on the PC.
7)
A Host Not Found Error is displayed if WinKeyer mode is started without an active PC host.
To exit WinKeyer mode, close the host application and then press the encoder pushbutton. This will return
control of the WK3-IC to the K45 controller and the K45 operating system will restart
Control Commands
To issue these commands, the user holds the CTL key down while pressing the specified key. Even though
the commands are shown in caps, the shift key does not need to be pressed. (Note: CTL-n = ^n)

CTL-C – Start Fast Callsign Capture
A callsign can be captured and saved while it is being sent on the paddles or by keyboard. A detailed
description of this function can be found on page 11 (Fast Callsign Capture Feature).
CTL-D - Decrement Key Weighting
CTL-I - Increment Key Weighting
^D will decrease weighting by one percent and the ^I will increase weighting by one percent. There are hard
stops at 25% min and 75% max. Value changes are flashed on the status line, W:55 for example, and
automatically updated in the User's configuration.
CTL-E- Send Error Dits
Eight dits will be sent to signify an operator error. This a buffered command causing a # character to be
placed in the transmit buffer. Instead of ^E, the user can enter the # directly.
CTL-H – Show Control Command Help Menu
This brings up a brief list of the Control commands. Each description is intended to be just enough to jog a
