4-3Integration Seamless Switcher • Programmer’s Guide

Ethernet connection
The cable can be terminated as either a patch cable or a crossover cable (figure 4-2)
and must be properly terminated for your application:
•Patch (straight) cable — Connection of the ISS to an Ethernet hub, router, or
switcher that also hosts a controlling computer.
•Crossover cable — Direct connection between the ISS and a computer.

Default address

To access the switcher via the Ethernet port, you will need the switcher’s IP
address. If the address has been changed to an address comprised of words and
characters, the actual numeric IP address can be determined
using the front panel
(see IP information in chapter 3, Operation) or the Ping utility (see
Ping to determine the
switcher’s IP address or Ping to determine the Web IP address in
appendix A
, Ethernet
Connection, for more details). If the address has not been changed, the factory-
specified default is 192.168.254.254.
Symbols
Symbols (
X
n
values), defined below, are used throughout the discussions of the
switcher-initiated messages that begin on the next page and the command/
response table that begins on page 4-9. The symbols represent variables in the
switcher-initiated messages and the command/response table fields.
