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 3G-HD A sends this response when a hot plug event on the output is
detected (for example, when the unit is unplugged and reconnected).
Error Responses
When the DSC receives a valid command, it executes the command and sends a
response to the host device. If the unit is unable to execute the command because the
command contains invalid parameters, it returns an error response to the host.
E01 — Invalid input number
E06 — Invalid switch attempt in this mode
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid port number
E13 — Invalid parameter
E14 — Invalid command for this configuration
E17 — Invalid command for signal type
E22 — Busy
Using the Command and Response Table
The Command and Response Table for SIS Commands , beginning on page 49, lists
the commands that the DSC scaler recognizes as valid, the responses that are returned to
the host, a description of the command function or the results of executing the command,
and an example of each command in ASCII.
NOTE: Unless otherwise stated, upper- and lowercase text can be used interchangeably in the
commands.
