Remote
Configuration and
Control
This section describes the connections through which the DSC can be configured and
controlled remotely via SIS commands and describes the commands that are available.
Topics include:
• SIS Commands
• Windows-based Configuration Program
The DSC can be configured and controlled using the Extron Simple Instruction Set (SIS) of
commands. Commands are issued via a host computer attached to the front panel USB
port. To enter the commands, you can use an application such as the Extron DataViewer
utility, available at www.extron.com (see the DataViewer help file to use this interface).
SIS Commands
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the DSC 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).
DSC-initiated Messages
When a local event such as a front panel selection or adjustment takes place, the
DSC scaler responds by sending a message to the host. No response is required from the
host. Example scaler-initiated messages are listed here.
• Reconfig
]
The DSC sends this response when a change in the input frequency is detected.
• HplgO
]
The DSC HD-HD sends this response when a hot plug event on the output is
detected (for example, when the unit is unplugged and reconnected).
