The LINDY CPU Switch is now ready for connection to the mains using the mains power adapter supplied. It is important to apply power to the LINDY CPU Switch first, then power on the monitor and each of the computers in turn. Failure to switch the LINDY CPU Switch and computers on in the correct order can lead to the mouse and/or keyboard not being recognised by the computers when they are switched on. -

Page 22: Mouse Control
RS232 control is supported on all LINDY CPU Switches except the LINDY CPU 2 Switch LINDY CPU Switch can be controlled by a remote RS232 device. To select a channel the data rate of the sending device must be set to 1200 baud, 8 bits, no parity and 1 stop bit. No handshaking is used by the LINDY CPU Switch. - Page 23 For example, consider a situation where two LINDY CPU Switch units are connected together (as shown in figures 7 and 8). To connect to the computer attached to port 3 on LINDY CPU Switch B the user would hold down the hotkey keys then press keys pressed.

Page 34: Cable And Connector Specifications
CABLE SPECIFICATION All of the shared devices plug directly into the relevant ports at the rear of the LINDY CPU Switch. If you use an AT style keyboard you will need an AT (5 pin DIN female) to PS/2 (6 pin mini-DIN male) converter. -
Page 35: Cable Connection
CABLE SPECIFICATION These require a special converter to connect the RS232 lines present on the LINDY CPU Switch mouse ports to the RS232 port on a PC. The wiring is identical to that used by Microsoft for their autosensing mouse adapter and is shown below: Cables should be no longer than 30 metres. -

(PS/2 or RS232). If you move the mouse and the activity indicator (dot on 7 segment display) does not flash then the LINDY CPU Switch is not receiving data from the mouse. Check the mouse connection to the LINDY CPU Switch, try resetting the mouse using the reset function (section 3.3) or re-powering the LINDY CPU Switch. - Page 37 Re-power the LINDY CPU Switch, preferably from a switch on a wall socket rather then by plugging in the connector to the rear panel of the LINDY CPU Switch. Try switching off all the connected CPUs and switching on the LINDY CPU Switch first.
