Serial Communication

Other Special Functions (optional)

To add functionality to the current message, include one or more of the following special characters

order. See Flow Control
C Control Class Inquiry
D Default value/Text
E Enable Control Inquiry
G Access Group Inquiry
H Return the Help text for a control
L Return a list of options for 'list' controls
M Find min/max adjustments (i.e., range)
N Return the name of the 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 are enclosed in double quotes following the data, as in "Name".
