Psion Teklogix also provides a 24-key keypad which can be mounted onto the
device, with a protection class IP 65.
3.2 Mouse
Any PS/2-compatible mouse with a standard Mini-DIN plug, USB connector or RS-
232 port can be connected to the 8580/8590. If the mouse has a PS/2 connection, a
Y-cable is also required
Note: It is not possible to use a PS/2 mouse during Touch operations if you use
the touch controller in PS/2 mode.However, a USB mouse or a RS-232
mouse can always be used in combination with touch mode.
Resources for the PS/2 mouse controller are pre-defined in the system architecture
and automatically managed by the BIOS. This is also the case for RS-232 and USB
mouse devices.
Special functions, such as those provided by wheel mouse devices, frequently
require additional drivers, which are to be supplied by the manufacturer.
