Prefix Characters (Optional); Projector Numbers (Optional); Function Code; Subcode - Christie Matrix StIM-WQ User Manual

Prefix Characters (optional)

For acknowledgement that the projector has responded, and/or to maximize message integrity, insert
one or two special characters before the 3-character Function code:
Special Character
$
#
&

Projector Numbers (optional)

To control a selected projector or controller within a group, include its assigned number or address
just before the 3-character ASCII Function code. See

Function Code

The projector function you wish to work with, such as input selection or gamma, is represented by a
3-character ASCII code (A-Z, upper or lowercase). This Function code appears immediately after the
leading "(" (left bracket) that starts the message. In messages sent to the projector that do not
have a Subcode, a space between the Function code, and the first parameter (or special character) is
optional.

+Subcode

The projector function you wish to work with may have one or more subcodes that will allow you to
select a specific source, image, input or subfunction. The Subcode is represented by a 4-character
ASCII code (A-Z, upper or lowercase, and 0-9). This Subcode appears immediately after the Function
code, with a "+" character to separate the code, and subcode. If there is no Subcode, the "+" (plus
sign) is also omitted. In messages sent to the projector that do have a subcode, a space between the
subcode and the first parameter (or special character) is optional.

Request/Reply Symbols

If the controller is requesting information from the projector, a "?" (question mark) appears directly
after the Function code. If the projector is replying, an "!" (exclamation mark) appears directly after
the Function code. For Set type messages sent to the projector, neither of these characters appear.
Data directly follows the code and subcode.
