SIS Configuration and Control
The XTP T UWP 202 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 23). This section contains basic SIS communication details and SIS
commands and responses when connected directly to the XTP T UWP 202. 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 UWP 202, connect the
computer to the XTP T UWP 202 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 UWP 202 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 transmitter is connected through the serial port only and a local event occurs, the
device responds by sending a message to the host.
The following copyright messages are displayed after a power cycle via RS-232. The specific
message displayed depends on the XTP T UWP 202 model.
