3.7 RS232 control
LINDY CPU Switch Multiscreen 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
Multiscreen. 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. The LINDY CPU Switch Multiscreen will echo the
ASCII character back to the sending device when the channel has been changed.
The serial interface pins are found on the options connector on the rear of the
LINDY CPU Switch Multiscreen. Pin assignments for this connector are given in
appendix A
3.8 Cascading LINDY CPU Switch Multiscreens
LINDY CPU Switch Multiscreen switches can be connected together to expand the
number of connected computers. When cascading LINDY CPU Switch Multiscreens
a power adapter must be connected to each LINDY CPU Switch Multiscreen. LINDY
CPU Switch Multiscreens can be connected in a cascaded tree structure. 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 Multiscreen. The channel can be selected on
remote LINDY CPU Switch Multiscreen units using an extension of the HOTKEY
control .
