The XKR-32 Rack Mounted KVM is a special X-keys device designed to
work specifically with KVMs. In PID #2 the XKR-32 Rack Mounted KVM is only
a keyboard, no input or output reports are available thus making it compatible
with KVM units. The information below is relevant only to PID #1
which does contain an input and output endpoint. Please note that the
XKR-32 Rack Mounted 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 on the right side of the device while plugging it into the usb port.
By default the XKR-32 Rack Mounted 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).
XKR-32 Rack Mounted 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.

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 an output report: Generate Data which is very useful for obtaining the initial state of the device immediately after enumeration.

X-keys XKR-32 Rack Mounted KVM Output Report
The following types of output reports are shown in the summary below. These commands are applicable only 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.

21. Check Dongle Key
Checks the key that was entered in Set Dongle Key. This is intented to be done by the developer within their own software to determine if the connected X-keys device is the one they sold to the customer. 4 random bytes along with the actual key are entered into the DongleCheck2() hash function of the Piehid32.dll/PieHid32Net.dll which returns 4 bytes. Then after sending this output report a Check Dongle Key input report will be received containing the same 4 bytes returned from the hash if the key matches.
