Out nn In nn
(where Out nn is the window number, and In nn is the input
number).
The MGP 462 sends this response when an input is switched.
Error responses
When the MGP 462 receives a valid SIS command, it executes the command and
sends a response to the host device. If the MGP is unable to execute the command
because the command is invalid or contains invalid parameters, it returns an error
response to the host. The error response codes are:
E01
— Invalid input channel number (too large)
E09
— Invalid function number (too large)
E10
— Invalid command
E11
— Invalid preset number
E12
— Invalid output number (applies for addressing windows)
E13
— Invalid value (out of range)
E14
— Invalid command for this configuration
E17
— Invalid command for signal type
E24
— Privilege violation
E26
— Maximum number of users connected has been exceeded
E27
— Invalid event number
E28
— Bad filename/File not found
Error response references
The following superscripted numbers are used within the command descriptions
on the following pages to identify commands that may respond as shown:
14
= Commands that give an E14 (not valid for this configuration) response if the
unit’s current configuration doesn’t support that command
24
= Commands that give an E24 (privilege violation) response if you are not
logged in at the administrator level.
27
= Commands that may yield an E27 (invalid event number) response.
28
= Commands that may give an E28 (file not found) response.
Telnet and Web communications
The MGP 462 can also be controlled via an IP connection using either Telnet
(port 23) or a Web browser (port 80). The ASCII and URL commands listed in the
tables later in this chapter perform the same functions, but they are encoded
differently to accommodate the requirements of each port (Telnet or browser).
The ASCII to hexadecimal (hex) conversion table on the next page is for use with
the command/response tables for the IP control port commands, which begin on
page 4-18.
