Simple Instruction Set

Host-to-interface Communications

The Extron Simple Instruction Set (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 unit executes the command and sends a response to the host
device. All responses from the unit 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 unit receives a valid SIS command, it executes the command and sends a response
to the host device. If the unit is unable to execute the command because the command is
invalid or it contains invalid parameters, the unit returns an error response to the host. The
error response codes are:
E10 — Invalid command
E12 — Invalid output number
E13 — Invalid range
E22 — Busy

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The
command operation is aborted with no other indication.
