SIS Configuration
and Control
The XTP SR HDMI can be configured and controlled using the OSD menu (see On-Screen
Display Menu System on page 15), Extron Simple Instruction Set (SIS) commands,
or the XTP System Configuration Software (see XTP System Configuration Software
on page 32). This section contains SIS communication details and SIS commands and
responses when connected directly to an XTP SR HDMI. Topics in this section include:
•
Host Device Connection
• SIS Overview
• Command and Response Tables for SIS Commands
Host Device Connection
Use a connected computer running the Extron DataViewer utility to send and receive SIS
commands and responses. To connect directly to an XTP SR HDMI, connect the computer
to the XTP SR HDMI through the front panel USB configuration port (see
figure 9 ,
B
on
page 14) or the rear panel Remote RS-232 connector (see figure 2 ,
H
on page 4).
The protocol for the serial port is as follows: 9600 baud, no parity, 8 data bits, 1 stop bit, no
flow control.
SIS Overview
Host-to-Device and Device-to-Host 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 XTP SR HDMI determines that a
command is valid, it executes the command and sends a response to the host device. All
responses from the receiver to the host end with a carriage return and a line feed
(CR/LF =
]
), which signals the end of the response character string. A string is one or
more characters.
Device-Initiated Message
When the device is connected through the serial port only and a local event occurs, the
device responds by sending a message to the host.
