Extron electronic DSC HD-3G A, DSC 3G-HD A manual DSC-initiated Messages, Error Responses

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.
