6.2 Setting the Dipswitches
The dipswitches (see Table ) on the rear panel should be set when the
switcher is operated via the RS-232 or RS-485/422 connector, or when it is
interconnected with other switchers. These switches allow proper
configuration of the control signals received and transmitted through the
RS-232 control port. The switcher allows master/slave configurations. This
allows switchers that are interconnected to operate independently, or in
conjunction with each other.

6.3 Jumpers, their Uses and Set-up Requirements
The switcher has additional adjustments and settings. These include the
internal jumpers.
WARNING!
Mains voltage is accessible inside the switcher, so always turn off the switcher
and remove its power cable from the mains socket before removing its cover.
The jumpers’ functional operation is described below:
Each switcher input has its own internal jumpers, numbered from J22 to
J27 and they are factory located in the position that provides a 75ohm
input termination. If the 75ohm termination is not required, the jumper
must be relocated to its alternate position (floating on the pin remote
from the input socket and not connected in any circuit). The particular
input is now "High-Z" (not 75ohm terminated) and may be used for
looping
