Projector Control 1 SETTING UP To enable serial control, do the following: • Remove the check mark from “Serial Mouse” in the Projector’s FEATURE MENU. This changes the Baudrate from 1200 to 9600 and turns of 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

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 is 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

Projector Control Currently there is only one type of body so the size is fixed to 0x0006. The CRC field contains the CRC of the message. The CRC algorithm is given in Appendix 1. To disable CRC set CRC_lo=0x00 and CRC_hi = 0x00. The Message Head – if the CRC are disabled – then looks like the following string: 0xBE 0xEF 0x80 0x06 0x00 0x00 0x00. This Head will be present in all strings sent to the projector from the host. 4.1.2 Message Body The message body has the following structure: Byte 0

Projector Control 5 COMMAND RETURN CODES The Serial protocol returns an acknowledgment (“return code”) for every packet sent. If the host sends a packet, then the projector acknowledge the receipt of this packet. The return codes are detailed in the table below. Command Return Code Name Return Code Value Description ACK 0x06 Packet acknowledged – no errors. Normal response when receiving NAK 0x15 Packet not acknowledged – some error occurred in receiving this packet. Usually Indicates a CRC erro

Projector Control APPENDIX 1: CRC CALCULATION ALGORITHM The following ‘C’ code can be used to calculate the 16-bit CRC required for all packets. The CRC is contained in the packet header and is calculated for the entire packet (header plus body). The CRC calculation is performed with the CRC bytes of the packet header initialized to zero. // Using two 256 byte lookup tables, quickly calculate a 16-bit CRC on // a block of data. // Params: // pcData : Pointer to data to calculate CRC on. // nCoun
