Commands and Responses

Error Responses

When the DSC 301 HD 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.

Error Numbers

E01	— Invalid input number	E14	— Not valid for this configuration
E10	— Invalid command	E17	— Invalid command for signal type
E11	— Invalid preset number	E22	— Busy
E13	— Invalid parameter	E25	— Device not present

Error Response References

14= Commands that give an E14 (invalid command for this configuration) error if sent to a product whose current configuration does not support the command

Using the Command and Response Tables

The command and response table for SIS commands later in this chapter lists the commands that the DSC 301 HD scaler recognizes as valid, the responses that are returned to the host, a description of the command’s function or the results of executing the command, and an example of each command in ASCII (Telnet) and URL encoded (web).
