3.8 Mouse control
The channels can conveniently be changed on the LINDY CPU Switch by using a three button
mouse or IntelliMouse. In order to switch to the next channel simply hold down the central mouse
button or wheel button and click on the left hand mouse button. The channel will then change.
3.9 RS232 control
IMPORTANT NOTE
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. Simply send the character for the channel which needs to be
selected, for example ASCII ‘1’ (hex code 31) will select channel 1, ASCII ‘2’ (hex code 32) will
select channel 2 and so on. Ports 10, 11, 12, 13, 14, 15 and 16 are selected by sending ASCII
codes A, B, C, D, E, F and G respectively.
3.10 LINDY CPU Switch Remote control
IMPORTANT NOTE
The remote control is only supported on the LINDY CPU 4, 4 OSD & 8 OSD Switches
This small remote control device (see figure 5) duplicates the LED and SELECT key off the front of
the LINDY CPU Switch to provide a remote means of switching channels. The status display
shows the channel selected and mouse / keyboard and data activity.
3.11 Cascading LINDY CPU Switches
Any number of LINDY CPU Switches can be connected together to expand the number of
connected computers. This can be particularly useful where clusters of computers are located
some distance from each other because each unit acts as data booster and can each be up to 30
metres away from the next LINDY CPU Switch. The channel can be selected on remote LINDY
CPU Switch units using an extension of the HOTKEY control function or using the On Screen
Menu which will store over 300 names. The On Screen Menu is recommended for selecting
computers on cascaded LINDY CPU Switches as this avoids the need to use long hotkey
sequences that may be hard to remember. When using the On Screen Menu, limit the cascade
depth to three levels (the maximum number of port digits that can be added to the menu).
