Host-to-GSS communications
SIS commands consist of one or more characters per field. No
special characters are required to begin or end a command
character sequence. When a command is valid, the GSS executes
the command and sends a response to the host device. All
responses from the GSS to the host end with a carriage return
and a line feed (CR/LF =
]
), which signals the end of the
response character string. A string is one or more characters.
Error responses
When the GSS receives a valid SIS command, it executes the
command and sends a response to the host device. If the GSS is
unable to execute the command because the command is invalid
or it contains invalid parameters, the GSS returns an error
response to the host. The error response codes are:
E10
]
- Invalid command
E13
]
- Invalid value (out of range)
E14
]
- Not valid for this configuration
E17
]
- System timed out
E22
]
- Busy
E24

E25

- Device not present
E26

- Maximum number of connections exceeded
E27
]
- Invalid Event number
E28

Timeout
Pauses of 10 seconds or longer between command ASCII
characters result in a timeout. The command operation is
aborted with no other indication.
Using the command/response table
The command/response table begins on the next page.
Uppercase or lowercase letters are acceptable in the command
field. Symbols are used throughout the table to represent
variables in the command/response fields. Command and
response examples are shown throughout the table. The ASCII
to HEX conversion table below is for use with the command/
response table.
