Prefix Characters (optional)
For acknowledgement that the projector has responded, and/or to maximize message integrity,
insert one or two special characters before the three-character Function code:
Projector Numbers (optional)
To control a selected projector or controller within a group, include its assigned number or address
just before the three-character ASCII Function code. See
Network Operation on page 71.
Function Code
The projector function you wish to work with, such as input selection or gamma, is represented by
a three-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 four-
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.
Special Character Description
$ Simple Acknowledgment, which will cause a ‘$’ character to be sent back from
the projector when it has finished processing the message. See Maximize
Message Integrity on page 69 .
# Full Acknowledgment, which will cause an echo of the message as a reply to be
sent back from the projector when it has finished processing the message. See
Maximize Message Integrity on page 69 .
& Checksum, which will allow a checksum to be put as the last parameter in the
message for verification at the projector. See Maximize Message Integrity on
page 69 .
