SIS Communication
and Control
The DVS 605 can be congured and controlled via a host computer or other device (such
as a control system) attached to the rear panel RS-232 connector or the LAN port or the
front panel USB port. Control is made using the Extron Simple Instruction Set (SIS) of
commands, or the DVS 605 Conguration Software Program, or the DVS default web
pages.
Commands can be entered using a Telnet application such as the Extron DataViewer,
available at www.extron.com. See the DataViewer Help le for use.
This section describes SIS communication and control. Topics that are covered include:
• Host to Scaler Communications
• Commands and Responses
The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no ow
control and the rear panel RS-232 captive screw connector has the pin
assignments as shown.

Host to Scaler Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the DVS 605 determines that a
command is valid, it executes the command and sends a response to the host device.
All responses from the scaler to the host end with a carriage return and a line feed
(CR/LF = ]), indicating the end of the response character string (one or more characters).
Scaler-initiated Messages
When a local event such as a front panel selection or adjustment takes place, the DVS 605
scaler responds by sending a message to the host. No response is required from the host.
Example scaler-initiated messages are listed here.
