Error Responses
When the VSC receives a valid SIS command, it executes the command and sends a response
to the host device. If the video scan converter is unable to execute the command because
the command is invalid or it contains invalid parameters, it returns an error response to the
host.
The error response codes and their descriptions are as follows:
• E01 – Invalid input channel number (the number is too large)
•
E09 – Invalid function number (the number is too large)
• E10 – Invalid command
• E13 – Invalid value (the number is out of range/too large)
Using the Command and Response Tables
The command and response table lists valid command ASCII codes, the video scan
converter’s responses to the host, and a description of the command’s function or the results
of executing the command. Lower case characters are acceptable in the command field
unless otherwise indicated. The following ASCII to HEX conversion table is for use with the
command/response table.

rate.
