Extron Electronics Annotator User Guide - Manual (Page 43)

SIS
Communication
and Control
The Annotator can be operated and configured using Simple Instruction Set (SIS)
commands input via a PC connected to either of the processor’s serial ports or the
Ethernet port.
See o and p on pages 8 and 10 , and “Ethernet Connection” section
for wiring details.
RS-232/RS-422 Link
The Annotator has two rear ports and one front port that can be used for serial control.
All ports enable use of SIS commands and the Windows-based control software. The
default protocol for these ports is:
• 9600 baud • 1 stop bit • no parity • no flow control • 8 data bits.
NOTE: The lower rear panel RS-232 port is designated as Comm1, the upper port is
Comm 3, and the front panel config port is Comm 2.
See p on page 10 for connection details .
Ethernet Connection
Ethernet (LAN) Port
The rear panel Ethernet connector on the unit can be connected to an Ethernet LAN or
WAN. Communications between the unit and the controlling device is via Telnet (a TCP
socket using port 23). The TCP port can be changed if necessary. This connection makes
SIS control of the unit possible using a computer connected to the same LAN or WAN. The
SIS commands and behavior of the unit are identical to that when communicating to it via
RS-232.
Ethernet Cabling
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application. See
“Ethernet Connection” section for
cable termination details.
Default IP Addresses
To access the Annotator via the Ethernet port, you need the Extron IP address and may
need the subnet mask and the gateway address. If the IP address has been changed to
an address comprised of words and characters, the actual numeric IP address can be
determined using the ping (ICMP) utility (see
“Ethernet Connection” section for more
details). If the addresses have not been changed, the factory-specified defaults are:
IP address: 192.168.254.254, subnet mask: 255.255.0.0, gateway address: 0.0.0.0
