SIS Configuration
and Control
The XTP T USW 103 can be configured and controlled using Extron Simple Instruction
Set (SIS) commands or the XTP System Configuration Software (see XTP System
Configuration Software on page 20). This section contains basic SIS communication
details and SIS commands and responses that are issued when a host is connected directly
to the XTP T USW 103. Topics in this section include:
• Host Device Connection
• Simple Instruction Set Control
• Command and Response Tables for SIS Commands
Host Device Connection
Use a computer running the HyperTerminal or Extron DataViewer utility, or a control system
to enable serial control of the switcher. To connect directly to an XTP T USW 103, connect
the computer to the XTP T USW 103 through the front panel USB Config port or the rear
panel RS-232 connector. The protocol for the serial port is as follows: 9600 baud, no parity,
8 data bits, 1 stop bit, no flow control.
SIS Programming Guide
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 T USW 103 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 = ]), which signals the end of the response character string. A string is one or more
characters.
Device-Initiated Message
When the switcher is connected through the serial port only and a local event occurs, the
device responds by sending a message to the host.
