SIS Configuration
and Control
The SMX can be configured and operated using the Extron Simple Instruction Set (SIS) of
commands. SIS commands can be run from a PC connected to either of the SMX serial ports
or the Ethernet port.
This section describes the SIS command method of communication and control. Topics that
are covered, includes:
•
•
•
•
RS-232 or RS-422 Link
The SMX has two ports that can be used for serial control. The default protocols for both
serial ports: 9600 baud, 1 stop bit, no parity, no flow control, 8-bit (see b on
page
Ethernet (LAN) Port
The Ethernet connection makes SIS control of the SMX possible using a computer connected
to the same LAN or WAN. The SIS commands and behavior of the unit are identical whether
it is communicating via Ethernet, RS-232 or RS-422 (see
connection through the RS-232 or Ethernet ports).
Ethernet Cable
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see
Default IP Addresses
To access the SMX 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 (CMP) utility (see
