LAN SPECIFICATION

For operation of the XtenDD switcher, multiple mainframes and panels designed

for different applications can be connected and operated via a Local Area Network

LAN.

Caution:

The XtenDD switchers are real-time devices. Other devices con-

nected to the same LAN cabling will cause degradation in com-

munications and reduce the reliability of the Switcher.

Caution:

For the system to operate, the LAN cable MUST be 50 ohms and

the cable MUST be terminated with a 50 ohm termination on

EACH end.
