XTP T VGA Transmitter • SIS Configuration and Control 11
SIS Configuration
and Control
The XTP T VGA 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 16). This section contains basic SIS communication details and SIS
commands and responses when connected directly to the XTP T VGA. Topics in this section
include:
• Host Device Connection
• SIS Programming Guide
• 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 transmitter. To connect directly to an XTP T VGA, connect the
computer to the XTP T VGA through the front panel USB Config port
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 VGA 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.
Error Responses
When the XTP T VGA receives an SIS command and determines that it is valid, it performs
the command and sends the corresponding response to the host device. If the command is
determined invalid or contains invalid parameters, the transmitter returns an error response
to the host. The error response codes are:
E10 = Invalid command E13 = Invalid parameter
E11 = Invalid preset number E14 = Not valid for this configuration
E12 = Invalid port number E17 = Invalid command for signal type
