This changes the Baudrate from 1200 to 9600 and turns off the Serial mouse data. • Connect the serial (COM) port from the Host to the RS232 connector on the projector 1.1 Rs232 Control Cables Please order the following parts: Part Number Description 301.102A Mouse Cable 4 meter 301.113B PC Mouse Adapter RS232 Straight Table 1 1.2 RS232 Settings If SerialMouse is deselected the setting is: Parameter Default setting Baudrate 9600 Data bit 8 Parity bit None Stop bit 1 Flow Control None Table 2 If SerialMouse is selected the setting is: Parameter Default setting Baudrate 1200 Data bit 8 Parity bit None Stop bit 1 Flow Control None Table 3 . If the serial mouse is enabled the projector sends mouse data whenever the user moves the trackball on the Batmouse. Page 3 Version 1.0 Projector Control 2 GENERAL This document describes the Communication Protocol between a Proxima® Projector and a Computer (Host). By using this connection the Host will be able control the projector. . This document are HEX command based only and a regular Terminal program like hyperterminal etc. can therefore not directly be used unless the COM port are activated by the user. This document is aimed at control systems in general which is HEX based. 3 FUNCTION TYPE The Function is grouped in four different function types: Function type Comments Execute An execute function executes an action on the projector, i.e. only one state. State An State function performs a set operation from a predefined list of states. Not all values in the range have to be legal. State String As state but returns ASCII strings Adjust An adjust function is characterized by Maximum > Minimum. And all the integer values between Minimum and Maximum are legal. Table 4 4 PROTOCOL MESSAGES 4.1 Message Formats The message is always divided in a header and a body part: Message Head (7Byte) Message Body (6Byte) 4.1.1 Message Head The message head has the following structure: Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Magic Number Body size CRC 0xBE 0xEF 0x80 0x06 0x00 CRC_lo CRC_hi Table 5 All values is in hexadecimal indicated with the leading 0x. The Magic number is used for synchronizing the start of a message. The Body size is set to the number of bytes contained in the Body part of the message. Currently there is only one type of body so the si...
