The display is quite reduced in function: It only allows the selection of predefined icons representing

modeand state information. There are several icon sets available which are stored in the KeTop T10 itself.

The KeTop T10 has an Ethernet interface which allows exchanging information with the control. The fol

lowing information is exchanged between controller and the device:

• state of keyboard and joystick

• current orientation of the device

• current selected icons for display

As a communication protocol KVC (KEBA Virtual Channel) based on UDP/IP designed by KEBA is used.

The protocol also implements a transfer of parameters. Parts of the data exchange are handled cyclically

like a live check to detect connection errors between KeTop T10 is active.

The communication protocol is integrated into the firmware of the KeTop T10. The firmware also contains

all (inertial) sensor evaluation to derive the orientation of the device. Furthermore a small web server

on the device allows basic diagnosis and network settings.
