The Protocol is based on a ASCII commands. By using this protocol a Host will be able control the projector on a physical link. 2 SCOPE The physical link is not defined in this document. Therefore the protocol can either be implemented on top of RS-232, USB, Ethernet or other forthcoming communication methods. 3 FUNCTION TYPE The Function is grouped in four different function types: Function type Execute State Comments An execute function executes an action on the projector, i.e. only one state. A State function performs a set operation from a predefined list of states. Not all values in the range have to be legal. An adjust function is characterized by Maximum > Minimum. And all the integer values between Minimum and Maximum are legal. A query function is a read only function. Adjust Query Table 1 3.1 Legal Arguments Argument + ? E S? C X M D Comments Sets the function to the required state. Increases the value of the function one step. Decreases the value of the function one step. Sets the value of the function to the specific number. Requests current, max and min value of the function. Executes an action. Returns `0' if function is not supported Return `1' if function is supported Returns Current Value Return max value Returns min value Set the function to the default value Each Function type has a set of legal arguments: Function type State Adjust Adjust Adjust All Execute All All All All All Table 2 Page 3 4 COMMAND RETURN CODES If a valid command is received the projector executes the command and as an acknowledgment it replies to the projector by returning a copy of the command with the current value appended. If the projector receives an illegal command it replies by returning an error message. 5 COMMAND SYNTAX Every command consists of a command that is ended with a delimiter. The command consists off a function code, a separator, and an argument. A function code consists of 3-5 ASCII letters and begins with a letter [A-Z], [a-z] |---------------------Command----------------------------------| At the end of this document, the "Table of Serial Commands" lists all valid function codes. Any other combination of characters received before a delimiter will result in an error response from the projector to the control unit (Host). 5.1 Delimiter HEX 0D 0A DEC 13 10 Comment The stop of a command is indicated by a carriage return = Line feeds after CR is ignored. ASCII ^M ^L Table 3 5.2 Separator HEX 3B DEC 59 Comment Used as a separator between the function code and the argument ASCII ; Table 4 5.3 Command Example |------------------------Command---------------------------------| BRG ; 55 Always initiate programming by sending a carriage return Page 4 6 ERROR SYNTAX If an command isn't available the projector response with an error message: |------------------------------------ Error message ----------------------------------| <(Command)> <> ASCII ! Table 5 HEX 21 DEC 33 Comment Error is always started with an Error Mark The following error codes are defined: 1000; 1001; 1002; 1003; 1004; 1005;< Projector not ready to be turned on> 1006; 1007; 1008; 2000; 2001; 2002; 6.1 Error Example ASK>BRX;50 <(Command)> <> ! (BRX;50) 1000 ; Page 5 7 TRANSACTION EXAMPLES Character string is in ASCII code and is carriage return: Adjust function: ASK>BRG;?

Also disable keyboard and remote after Power On with: IRRE;0 KBRD;0 These two command isn't saved so it's recommended to always set them after the PWR;1 command. 9.1 Setting Up To enable serial RS-232 control do the following: · · · Power up the projector Connect the serial (COM) port from the Computer (Host) to the RS-232 port on the projector by using the optional twisted serial cable mentioned below under CABLES. Power up the computer. On the PC side a software that can perform a "terminal emulation" is needed. This is a standard component in most operating systems, and it is also available as stand alone software. Norton PCAnywhere and Norton Commander are two programs that can do this. As it is a standard component in the Windows Operating System, we recommend that HyperTerminal is being used. This can normally be found in the accessories menu. Set the Computer serial port settings as shown below: Default is 9600 baud - 8 bit - No parity - No flow control - 1 stop bit Press ENTER (sending a carriage return) and the projector should respond by sending a prompt (ASK>). The projector is now ready to receive commands. · 9.2 Cables Optional twisted RS-232 cable part# 301.159. 9.3 Communication Protocol Default setting 9600 8 None 1 None Valid values for direct setting 9600, 19200 bps none none none none Parameter Baudrate Data bit Parity bit Stop bit Flow Control Page 10
