Connection and use
Once you have connected your computer to either the RS232 IN port (depending on which standard is
supported by your computer) or to the Ethernet port on Christie TruLife+, you can remotely access
controls and image setups, issue commands or queries, and receive replies.
Use these bidirectional messages to:
• Control multiple projectors
• Obtain a projector’s status report
• Diagnose performance problems
Refer to the User Manual provided with the projector for all cable requirements and other connection
details.
Some commands are operational only when projector is powered up.
Connecting to a computer or server with 10/100/1000 base-T
Ethernet
Communicate with a remote computer
, server, or an existing network using a RJ-45 cable.

Understanding message format
Commands sent to and from Christie TruLife+ are formatted as simple text messages consisting of a
three letter command code, an optional four letter subcode, and optional data.
Source Format Function Example
From controller (Code Data) SET (set power on) (PWR1) or (PWR 1)
(Code+Subcode
Data)
SET (set input port configuration) (SIN+PORT 1)
(Code ?) REQUEST (what is current power
state?)
(PWR?) or (PWR ?)
(Code+Subcode ?) REQUEST (what is current input port
configuration?)
(SIN+PORT?)
From projector (Code Data) REPLY (power state is 1 "On") (PWR!001 "On")
(Code+Subcode
Data)
REPLY (input port configuration is 1
"One-Port")
(SIN+PORT!001 "One-
Port")
Generally, most commands include 0 or 1 data fields or parameters. Where applicable, a message may
expand to include additional parameters of related details.

020-103316-01 Rev. 1 (09-2020)
Copyright © 2020 Christie Digital Systems USA, Inc. All rights reserved.

The smallest step size for any parameter is always 1. For some controls (such as Size) the value
displayed on the screen has a decimal point (for example, 0.200 to 4.000). In this case, the values
used for the serial communications is an integer value (for example, 200 to 4000), not the decimal
value seen on the screen.
Available message types
Message type Description
Set A command to set a projector parameter at a specific level, such as changing the
brightness.
Request A request for information, such as what is the current brightness setting.
Reply Returns the data in response to a request or as confirmation of a command.
Basic message structure
Understand the component fields that comprise a standard ASCII message.
Components Description
Start and end of message Every message begins with the left bracket character and ends with the right bracket
character.
If the start character is received before an end character of the previous message,
the partial (previous) message is discarded.
Prefix characters (optional) To acknowledge that Christie TruLife+ has responded, and/or maximize message
integrity, insert one or two special characters before the three-character function
code:
• $ (Simple Acknowledgment)—Causes a dollar sign ($) character to be sent from
Christie TruLife+ when it has finished processing the message.
• # (Full Acknowledgment)—Causes an echo of the message as a reply to be sent
from Christie TruLife+ when it has finished processing the message.
• & (Checksum)—Allows a checksum to be put as the last parameter in the
message for verification at Christie TruLife+.
Function code The Christie TruLife+ function you want to work with, such as channel selection or
gamma, is represented by a three-character ASCII code (A-Z, upper or lower case).
This function code appears immediately after the leading bracket that starts the
message. In messages sent to Christie TruLife+ that do not have a subcode, a space
between the function code and the first parameter (or special character) is optional.
+Subcode The Christie TruLife+ function you want to work with may have one or more
subcodes that allow you to select a specific source, image, channel or subfunction.
The subcode is represented by a four-character ASCII code (A-Z, upper or lower
case, and 0-9). This subcode appears immediately after the function code, with a
plus sign (+) character to separate the code and subcode. If there is no subcode, the
plus sign (+) is also omitted. In messages sent to Christie TruLife+ that have a
subcode, a space between the subcode and the first parameter (or special character)
is optional.

Components Description
Request/reply symbols If the controller is requesting information from Christie TruLife+, a question mark (?)
appears directly after the function code. If Christie TruLife+ is replying, an
exclamation mark (!) appears directly after the function code. For set messages to
Christie TruLife+, neither of these characters appear—data directly follows the code
and subcode.
A request for information is represented by a question mark (?) that appears directly
after the function code. A reply is represented by an exclamation mark (!) that
appears directly after the function code or subcode, if one is provided. The first
parameter located after the exclamation mark (!) reply character cannot have a
space, for example (PWR!000).
Data The value for a given Christie TruLife+ 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—such as before the data—in a set message, but data in
replies follow the exclamation mark (!) symbol without a space. Other details to
remember about data:
• All values returned by Christie TruLife+ (reply messages) have a fixed length,
regardless of the actual value. For a specific parameter, the length is always the
same (for example, contrast is always returned as three characters, Christie
TruLife+ number is always returned as five characters). The minimum
parameter size is three characters. Values less than the predefined size are
padded with leading zeros as needed. Parameters which have negative signs are
zero padded after the negative sign, and have one less digit to make space for
the sign.
• Data in set messages to Christie TruLife+ 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.
Text parameters Most data is simply a numerical value; however, some messages also require text.
For example, a channel naming message typically includes a text-based name—
enclose this text in double quotation marks, as in "Tilt the Wagon". For example, the
time command requires time to be provided in text enclosed in double quotation
mark, as in "19:45:23". Use all characters as required except for special characters
—these require a two-character combination.

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 0 0 0 )
HEX = 0x28 0x4 0x50 0x28 0x21 0x32 0x30 0x30 0x30 0x29
Maximizing message integrity
For additional reassurance and/or maximum message integrity, insert one or two special characters.
Message
requirement
Description
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.

Message
requirement
Description
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).
• Full Acknowledgments—Insert a hash (#) character just after the start code bracket.
This returns the message sent, as a reply.
This is a quick way to confirm success with set messages and is useful with long distance
communication links or where the projectors and/or images are not visible from the
controller. Acknowledgments can also be a type of flow control.
Checksums For maximum message integrity, add a checksum character ampersand (&) just after the
start code bracket. You must also include the correct checksum total (0-255) just before
the end code bracket. Make sure to add a space before the calculated checksum to
separate it from the last data parameter:
The checksum is the low byte of the sum of the ASCII values of all characters between the
start bracket and the beginning of the checksum, but not including either. It does include
the space in front of the checksum.
Calculate the checksum for the above set contrast to 64 command as follows:
CHECKSUM EXAMPLE = & + c + o + n + 6 + 4 + ‘space’
= 26h+63h +6Fh +6E h +36h +$34h +$20h
= 01F0h
= F0h when only the low byte is used
= 240
Christie TruLife+ 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.
Note the following:
• h indicates a hex number.
• If a request message has a checksum, so does the reply.
• If using both acknowledge and checksum, either character can occur first.
Error messages
If a command cannot be performed, a descriptive error identifying the problem appears.
For example, the following message indicates a syntax error:
(ITP) - (65535 00000 ERR00005 "ITP: Too Few Parameters")

Flow control
Normally messages can be sent to the projector before processing of earlier messages is complete—
Christie TruLife+ stores messages in a buffer until ready to process. However, if a series of messages
is sent, Christie TruLife+ may not be able to process them as fast as they arrive and the buffer
becomes full.
If this happens, Christie TruLife+ sends the 13h (Xoff) code to instruct the controller (or any devices
preparing to transmit) to cease transmission. At this point, the controller must respond immediately
and send no more than 10 extra characters or they may be lost (such as, Christie TruLife+ can
accommodate the receipt of up to 10 more bytes after it sends 13h (Xoff)). When the buffer is once
again available, Christie TruLife+ sends a 11h (Xon) command to resume transmission.
Xon and Xoff controls apply to both directions of communication. Christie TruLife+ does not send more
than three characters after it has received a 13h (Xoff) code.

Defines a custom color table using x,y
coordinates, scaled by a factor of 10,000.
For example, an x value of 3350
corresponds to x=0.3350 in the CIE 1931
chromaticity scale.
This command is only available if the video
electronics are on and Custom is selected.
(Saved value)
The valid range for each value
depends on which of the red/
green/blue point is being
adjusted.

Sets the native color primaries for the
projector using the x,y coordinate form,
scaled by a factor of 10,000. For example,
an x value of 3350 corresponds to x=0.3350
in the CIE 1931 chromaticity scale.
This command is only available if the video
electronics are on and Max Drives is
selected. It is only available to a service
user.
The valid range for each value
depends on which of the red,
green, blue, or white point is
being adjusted.
CCA+RSET Resets the native color primary settings to
their defaults.
If primary settings have not been saved
(CCA+SAVE), this resets the primary
settings to hard-coded defaults.
This command is only available if video
electronics are on. It is only available to a
service user.
—
CCA+SAVE Saves the current primary settings (for
example, CCA+RDPX, and so on) as the new
default color primary settings.
Save these settings after calibrating the
color primaries (such as measuring the
primary x,y coordinates using a
spectroradiometer or similar equipment).
This command is only available if video
electronics are on. It is only available to a
service user.
