Setting Jumpers
The Terminal Server contains jumpers that you might want to set before you configure it and put
it into production. You can set the power out pin (not on the DB9 model) to a fixed 5V DC output
or to the external adapter output; this can range from 9-30V DC (the external adapter that is
shipped with the Terminal Server has a 12V DC output). By default, the power out pin is set to no
power. You can set the Terminal Server line termination to
on
or
off
(this is
off
by default) if
you are using EIA-422/485.
