SIS Programming Guide

Host-to-SMX and SMX-to-Host Communications

SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the SMX determines that a
command is valid, it executes the command and sends a response to the host device. All
responses from the switcher 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.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by
sending a message to the host. The switcher-initated messages are listed below.
With an RS-232 or RS-422 connection to a computer (upon power up):

With an Ethernet connection:

The SMX initiates the copyright message when powered on or when connection via Internet
Protocol (IP) is established.

Vx.xx

is the firmware version number.

Password:

The SMX initiates the password message immediately after the copyright message when
the controlling system is connected using TCP/IP or Telnet and the SMX is password
protected. The SMX requires an administrator or user level password before performing the
commands entered.

NOTE: The

Password

prompt is re-displayed if an incorrect password is entered.

The SMX initiates the

Qik

message after front panel switching.

Rprnn

Rpr

message when a memory preset has been recalled from the front

panel. “

nn

” is the preset number.

Sprnn

]

The SMX initiates the

Spr

message when a memory preset has been saved from the front

panel. “

nn

” is the preset number.

Reconfig

]

The SMX sends the

Reconfig

message whenever power is cycled, the plane address is

changed, or the output board is installed or uninstalled.

NOTE: The response given is seen via an RS-232 or RS-422 connection only.

ppInnn

Audxx

The SMX initiates the

Aud

message when a front panel input audio level change has

occurred. “

pp
