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.

Start-up message

When a local event, such as a front panel operation or error

condition, occurs, the unit responds by sending a message to the

host. The unit-initiated messages are listed below:

Vx.xx, 60-927-xx]]

The FOX DA issues the copyright message when it ﬁrst powers

on. Vx.xx is the ﬁrmware version number, 60-927-xx is the part

number.

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]

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 page 3-6. Lower case

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.

response table ﬁelds.
