Error Responses
When the MGP Pro receives a valid SIS command, it executes the command and sends a
response to the host device. If the processor 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 for this configuration
E17
— Invalid command for signal type
E22
— Busy
E24
— Privilege violation
E26
— Maximum number of users connected has been exceeded
E27
— Invalid event number
E28
— Bad filename/File not found
Telnet and Web Communications
SIS commands can also be issued via an IP connection using either Telnet (port 23) or a
web browser (port 80). The ASCII and URL commands listed in the tables in this section
perform the same functions but are encoded differently to accommodate the requirements
of each port (Telnet or browser).
The ASCII to hexadecimal (hex) character conversion table below is for use with the
command and response table (see

The command and response tables list valid ASCII (for Telnet) command codes, the
corresponding URL encoded (for web browsers) command codes, the responses of the
processor to the host, and a description of the command function or results from executing
the command.
