PVS 407D • SIS Communication and Control 19
SIS Communication
and Control
The switcher can be configured and controlled with Extron Simple Instruction Set (SIS)
commands when connected to a host computer or other device (such as a control system).
Attach the host device to the rear panel RS-232 connector, the LAN port, or the front
panel USB port. Commands can be entered using a Telnet application such as the Extron
DataViewer, available at
www.extron.com (see the DataViewer Help file for more details).
This section describes SIS communication and control. Topics in this section include:
•
Host and Switcher Communication
•
System Definitions
• SIS Overview • Command and Response Tables
The switcher uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control (see
Control Ports on page 7).
Host and Switcher 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 switcher 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 =
]
), indicating the end of the response character string (one or more characters).
Switcher-Initiated Messages
When a local event such as a front panel selection or adjustment takes place, the PVS 407D
responds by sending a message to the host. No response is required from the host.
Example switcher-initiated messages are listed here.

Password Information
The

Password: prompt requires a password (administrator level or user level) followed
by a carriage return. The prompt is repeated if the correct password is not entered. If the
correct password is entered, the unit responds with

, depending on password entered. If passwords are the same for both
administrator and user, the unit defaults to administrator privileges.
