The projector collects all of the message bytes as defined in the first byte of the message, then creates its own
checksum value for comparison with the checksum included in the controller's message. If the values match, the
message is considered to have been correctly received— otherwise the message is discarded.
NOTES: 1) 'h' indicates a hex number. 2) If a "request" message has a checksum so will the reply. 3) If using both
"acknowledge" and "checksum", either character can occur first.
Accessing Specific Source Setups
For ASCII messages described in this document, it is assumed you are adjusting the current source setup (channel)
rather than a different specific one. However, for several commands (for example, ASR, Auto Source) you can
direct the message to particular source setup. To do this, insert an "S" and a source# (such as "S5") before the
parameter value—the source setup number can be thought of as a "P0" parameter prior to the first parameter,
and can be preceded with an optional space. For example:
(ASR S25 1)
Use "S0" if your setting should be applied to all source setups (channels):
(ASR S0 1)
The "S" source setup function cannot be used for parameters affecting the projector as a whole such as projector
address.
Other Examples:
(ASR 1)
(ASR? S5)
(ASR!S005 001)
(ASR? S7)
(ERR 006 "ASR: Source does not exist") = Source setup #7 does not exist
(ASR?)
(ASR!000)
Other Special Functions
To add functionality to a message, include one or more of the following special characters directly after the start
code "(". If you add more than one, they can be in any order.
PARAMETER LIMITS: For single‐parameter projector function codes, you can find out the current range of
adjustment by adding the letter "M" to your request message. For example:
(LPL?M)
(LPL!M000 5000)
Ranges cannot be determined in this manner if the function has multiple parameters. Note also that for text‐based
parameters, the "M" values represent the shortest and longest text strings possible.
= Turn Auto‐Source on for source setup #25
= Turn Auto‐Source on for all source setups
= Turn ASR on for the current source setup
= What is the ASR status for source setup #5?
= ASR is on for source setup #5
= What is the ASR status for source setup #7?
= What is the ASR status for current source setup?
= ASR is off for current source setup
What is the minimum and maximum lamp limit?
Minimum lamp limit = 0, maximum lamp limit = 5000.
