Using Simple Instruction Set (SIS) Commands

The DTP2 T 204 can be remotely set up and controlled via Extron SIS commands that are
issued from a host computer or other device, such as a control system. SIS commands can
be issued via RS-232 from the computer serial port to the switcher rear panel Remote port
(see
switcher front panel Config port, or Telnet (IP) from a computer Ethernet port to the switcher
rear panel LAN port.

Host-to-switcher Communications

SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. You can enter these commands from
your computer using a communication software program such as Extron DataViewer or
HyperTerminal. When the switcher determines that a command is valid, it executes the
command and sends a response to the host device.
Responses from the DTP2 T 204 to the host computer 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.

Switcher-initiated Messages

When a local event such as a front panel selection or change in signal status takes place,
the switcher responds by sending a message to the host, indicating what change has
occurred. No response is required from the host.
The switcher sends the following message when it is first powered on:
(C) Copyright 20nn, Extron, DTP2 T 204, Vn.nn, 60-1626-52
20nn is the year in which the copyright for the firmware was registered, Vn.nn is the
firmware version number, and 60-1626-52 is the switcher part number.
NOTE: This message is displayed at power-up only with an RS-232 or USB connection.
