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
P
L
!
2

HEX =

0x21

Maximizing message integrity
For additional reassurance and/or maximum message integrity, insert one or two special characters.

Description
Acknowledgments
For assurance from Boxer 4K (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 Boxer 4K (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 Boxer 4K. However, if
requested, the dollar sign ($) acknowledgment from Boxer 4K follows the reply.
There are two types of acknowledgments:
• Simple Acknowledgments—Insert a dollar sign ($) character just after the start code
bracket. This only returns a $. This only returns a dollar sign ($) on success, or a
caret (^) on failure (NAK).
