cables have these DDC lines connected.
Keyboard and PS/2 mice - 6 pin mini-DIN male connector to 6 pin mini-DIN male
connector with all lines connected straight through (1-1,2-2 etc.). If the PC has a 5-
pin DIN AT style keyboard connector you will need a PS/2 to AT keyboard adapter
6-pin mini-DIN female to 5-pin DIN male (readily available). For 'interface powered'
operation without the optional power adapter the cables should be no longer than 5
metres (see section 2.4 for more details). For operation with the power adapter,
cables should be no longer than 30 metres.
RS232 serial mice - these require a special converter to connect the RS232 lines
present on the LINDY CPU Switch Multiscreen mouse ports to the RS232 port on a
PC.
Cables should be no longer than 30 metres.
NOTE - There are several common wiring specifications for 6-pin mini-DIN to
9-pin serial adapters. If you have an adapter that has been supplied with a
mouse it may have a completely different internal wiring to that shown above
and may not be compatible with the LINDY CPU Switch Multiscreen
