COMPACT BIDIRECTIONAL AUTOSWITCHES
You can set the timeout period
between print jobs from 5
seconds up to 40 seconds.
Adjusting the switch‘s timeout
value higher is particularly useful
if you want to print long document
files with graphics or use a
printer’s spooler. This can be
done by setting the four DIP
switches on the side of the
switch.

In Auto-Link Mode, the switch
constantly scans its input ports
and sends the job to the attached
parallel device. The AutoSwitch
also has a Select button for
manual port selection.
