Extron electronic 42 HVA manual Using the Command/Response Table, Switcher Error Responses

Switcher Error Responses

When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (too large)

E10 — Invalid command

E12 — Invalid output number (too large)

E13 — Invalid value (out of range)
