communication utility, such as Telnet, to send SIS commands and view the responses.

Host-to-Interface Communications
SIS commands consist of one or more characters per field. No special characters are required
to begin or end a command sequence. When a command is valid, the interface executes the
command and sends a response to the host device. All responses from the interface to the
host end with a carriage return and a line feed (CR/LF =
response character string. A string is one or more characters.
Error Responses
When the interface receives a valid SIS command, it executes the command and sends a
response to the host device. If the interface is unable to execute the command because the
command is invalid or it contains invalid parameters, it returns an error response to the host.
The error response codes and their descriptions are as follows:
E10 – Invalid command
E13 – Invalid parameter
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 and Response Table
The
letters are allowed in the command field only as indicated. 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, on the next
page, is for use with the command/response table.
