Request/Reply Symbols; Other Special Functions (Optional; Data - Christie Entero RPMWU User Manual

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.

Other Special Functions (Optional)

To add functionality to the current message, include one or more of the following special characters between
the Function code/Subcode, and the first parameter. If more than one, add them in any order. See
Control.

Data

The value for a given projector state, such as "ON" or "OFF", appears in ASCII-decimal format directly after
the request/reply symbol. You can add an optional space after the symbol (i.e., before the data) in a set
message, but data in replies follow the "!" (exclamation) symbol without a space. Other details to remember
about data:
• All values returned by the projector (reply messages) have a fixed length, regardless of the actual value. For
a specific parameter, the length will always be the same (e.g. contrast is always returned as 3 characters,
projector number is always returned as 5 characters). The minimum parameter size is 3 characters. Values
that are less than the pre-defined size will be padded with leading zeros as needed. Parameters which have
negative signs (-) are zero padded after the negative sign, and will have one less digit to make space for the
sign.
• If entering a negative number, there must be a space between the code/subcode, and the value. For example,
(CRM3) and (CRM 3) can both be used when the number is positive. (CRM -2) is acceptable, but (CRM-2)
is not.
• Data in set messages to the projector do not require padding with zeros.
• Within each message, multiple parameters of data must be separated by one "space" character.
• Text parameters such as channel names are enclosed in double quotes following the data, as in "Name".
