The XK-80/XK-60 KVM is a special X-keys device designed to work specifically with KVMs. In PID #2 the XK-80/60 KVM is only a keyboard, no input or output reports are available. The information below is relevant only to PID #1 which does contain an input and output endpoint. Please note that the XK-80/60 KVM in PID #1 will NOT be compatible with most KVMs, it must operate in PID #2 to be compatible. To convert the device to PID #1 when it is currently in PID #2 hold and press the programming switch located at the top of the device while plugging it into the usb port. By default the XK-80/XK-60 KVM will return to PID #2 which is the desired PID for use with KVMs after each reboot however this can be changed using the Reboot Mode output report (described below).

XK-80/60 KVM is supported by P.I. Engineering Macroworks 3.1, X-key Basic Setup for PC users , P.I. Engineering SDK samples for Microsoft C# Express, VB Express, Microsoft C++ 2010 and Linux.

Endpoint: 3, Consumer Usage Page.

PID #1 Additional Endpoints: 1, Keyboard (Hid Usage Page 1, Hid Usage 6) and 2, Joystick (Hid Usage Page 1, Hid Usage 4).
PID #2 Additional Endpoints: 1, Keyboard (Hid Usage Page 1, Hid Usage 6) only for use with KVM. In this PID the only way to return to PID #1 is to press and hold the programming switch down while plugging the device into the usb port.

Report Length: 33 bytes.

1. General Incoming Data

This data is returned when new data is detected such as button presses, unit id change. This report can be manually stimulated by sending a Generate Data output report which is very useful for obtaining the initial state of the device immediately after enumeration.

PS: 0 if program switch unset, 1 if program switch is set, 2 if generated by the Generate Data (output report 6) and program switch is unset, 3 if generated by the Generate Data (output report 6) and program switch is set.
DI: For all bits 0 if key is up, 1 if key is down. Bits 1 to 8 correspond to the keys from top to bottom respectively of each column. For example a value of 3 in Byte 4 indicates that keys 0 and 1 are pressed.
Time: If enabled using Enable Time Stamp output report gives a time in ms starting from when the device was plugged into a port in 4 bytes where byte 14 is the MSB and byte 17 is the LSB.

X-keys XK-80/XK-60 KVM Output Report

The following types of output reports are shown in the summary below. These reports on only applicable when the device is in PID #1. Please be aware that several of these commands result in writing to the device's eeprom which has a limit to the number of writes allowed before it is "burnt out". The manufacturer's specification is 50,000 eeprom writes. Because of this we recommend the commands designated with e be executed rarely and not within timing loops. Note, the first byte listed in this documentation is 0 and represents the report ID. This is not present on some non-PC operating systems. So when sending an output report on Android for example, eliminate this byte.

18. Set Version Number

Send this output report to set the Version of the device. This is not the firmware version given in the descriptor but a 2 byte number available on enumeration. The value is "remembered" so if it is changed, using this report, the device must be rebooted. The device can be rebooted by replugging it or by sending the output report : Reboot Device. The device is also rebooted when changing pids using output report: Change PID.
