IN1804 Seamless Scaling Switchers • SIS Configuration and Control 48
SIS Configuration
and Control
The IN1804 series switchers can be configured and controlled via Extron Simple Instruction
Set (SIS) commands when connected to a host computer or other device (such as a control
system). Attach the host device to the rear panel RS-232 connector or LAN connector, or
to the front panel USB port. Commands can be entered using a Telnet application such as
the Extron DataViewer, available at www.extron.com (see the DataViewer Help file for more
details). The default protocol for the RS-232 connection is 9600 baud, 8 data bits, 1 stop
bit, no parity, and no flow control. This section describes SIS communication and control.
Topics in this section include:
• Host and Switcher Communication
• SIS Overview
• Command and Response Tables for IN1804 SIS Commands
Host and Switcher Communication
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the switcher determines that a
command is valid, it executes the command and sends a response to the host device. All
responses from the switcher to the host end with a carriage return and a line feed
(CR/LF =
]
), indicating the end of the response character string (one or more characters).
