VSC error responses

Using the command/response table

www.camboard.de
CAMBOARD Electronics
When a local event such as a front panel operation occurs, the scan converter
responds by sending a message to the host. The VSC-initiated messages are listed
below (underlined).
(C) Copyright 1998-1999, Extron Electronics, VSC 200/300, Vx.xx
The copyright message is initiated by the scan converter when it is first powered
on. Vx.xx is the firmware version number.
Reconfig
The Reconfig message is initiated by the scan converter when the resolution of the
input signal is changed and when the front panel LCD menus are exited, indicating
that there may have been a change to the adjustments or parameters.
The scan converter does not expect a response from the host, but, for example, the
host program might request a new status.
When the scan converter receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the scan
converter is unable to perform the command because the command is invalid or
contains invalid parameters, the scan converter returns an error response to the
host. The error response codes are:
E09 — Invalid function number (too large)
E10 — Invalid command
E13 — Invalid value (out of range)
The command/response table is shown on the next page. Lower case characters
are acceptable in the command field only where indicated. Symbols are used
throughout the table to represent variables in the command/response fields.
Symbol definitions are shown at the beginning of the table, as is an ASCII-to-
hexadecimal conversion table. Command and response examples are shown
throughout the table.
