Christie LX25 & LX25a Serial Communication

Section 1

Christie LX25 &LX25a Serial Communications

NOTE: There is no connect/disconnect command. The built-in keypad, IR remote and

RS-232 control will function simultaneously.

This Section Includes: 1.1 Overview…………………………………………………… ………page 1-1

1.1 Overview Christie LX25 serial communication allows the control of projectors by an

external controller, such as an AMX or Creston controller. Once connected to the RS-232 port of the projector, controllers can access projector controls and setups, issue commands and receive replies.

1.2 Connection To use Christie LX25 serial communications you must first connect the projector

to a PC or controller. Using an RS232 Null Modem cable (optional serial port cable is a null modem cable), connect the projector to the computer. Refer to Table 1 for Port Characteristics. Refer to Table 2 for projector wiring hook-up.

Christie LX25

Protocol: RS232C Baud Rate: 19200 bps Data Bits: 8 bits Stop Bit: 1 bit Parity : None Flow Cntrl: None

Table 1: Port Characteristics

NOTE: 1) To avoid damage, connect only properly wired RS-232 serial communication cables to the projector Serial Port. 2) Communication cables longer than 50 feet should be of high quality and low capacitance, well shielded and grounded.

CONTROL PORT CONNECTOR Terminal: 8-Pin Mini DIN Connect control port on your computer (PS/2, Serial (DB9) or ADB port) to this connector with the Control Cable (supplied).

Below are the wiring diagrams for the adapters that are used to connect to the Control Port on the projector.

1.3 Messages The Christie LX25 has two types of commands: Control Command and Status

Request Commands. Each command must be succeeded with a "CR" code, which is the equivalent to a carriage return. In hexadecimal the "CR" code is 0D.

The following delays are recommended: 10ms delay between characters. 100ms delay between commands. 300, 3000 or 5000ms delay between commands for the following: Check Table 3

Control Commands Control commands are used to set or modify various projector characteristics or to emulate key presses from the built in keypad/IR remote control. Note: Unless Display is set to OFF in the Setting Menu, most commands will cause an OSD to appear. Control commands follow the protocol:

Cxx(CR) Where XX is the command code (see Table 3 for a complete list of command codes) and (CR) is 0D.

Note:

Commands are listed in ASCII, but all communications (commands and replies) are hexadecimal. Ensure you are sending hexadecimal. Commands are case sensitive. Make sure to always send letters in upper case.

Example: As listed, Power On = C 0 0 (CR) You should send: 43h 30h 30h 0Dh When a control command is sent to the projector, a response is sent back to the controller to notify it about how the command was treated. There are two possible responses to a control command:

06 (CR) -- Command accepted and executed ? (CR) -- Command not recognized

Extended Control Commands Control commands are used to set or modify various projector characteristics or to emulate key presses from the built in keypad/IR remote control. Note: Unless Display is set to OFF in the Setting Menu, most commands will cause an OSD to appear. Control commands follow the protocol:

CF_ xx_## (CR)

Where _ is a space, XX is the command code and ## is the parameter (see Table 3a for a complete list

of extended control codes) and (CR) is 0D. When a control command is sent to the projector, a response is sent back to the controller to notify it about how the command was treated. There are two possible responses to a control command:
