What is sent in a message
Although you send and read messages as strings of ASCII characters, the actual message travels as a
sequence of bytes. Each character in this sequence requires one byte.
The following example illustrates a lamp limit is 2000 hours reply from the projector.
ASCII = ( L
HEX = 0x28 0x4
Maximizing message integrity
For additional reassurance and/or maximum message integrity, insert one or two special characters.
Message Description
requirement
Acknowledgments For assurance from Christie TruLife+ (or group of projectors) that a set message has been
processed, request an acknowledgment.
The acknowledgment is returned after the message has been received and fully executed
by Christie TruLife+ (such as in the case of a source switch it is not sent until the switch is
complete). If the message cannot be executed for some reason (such as invalid
parameters, time-out, and so on) a NAK is returned instead (not-acknowledge).
Requesting an acknowledgment serves no purpose when included in a request message,
as the acknowledgment is redundant to the actual reply from Christie TruLife+. However, if
requested, the dollar sign ($) acknowledgment from Christie TruLife+ follows the reply.
