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. -
Page 4: Message Body
The CRC algoritm 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. -
Page 5: Command Return Codes
5 COMMAND RETURN CODES The Serial protocol returns an acknowledgement (“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. - Page 6 Example 5: Hex sequence for get Brightness Host: => 0xBE 0xEF 0x80 0x06 0x00 0xBD 0x70 0x02 0x00 0x11 0x00 0x00 0x00 <= Projector (70%) 0x1D 0x00 0xB2 Example 5: To get ASCII Information Set Parameter in the State String function...

Page 9: Appendix 1: Crc Calculation Algorithm
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. - Page 10 // Lookup table used for hi-byte of CRC static const BYTE cCRCHiArray[] = { 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x01,0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80,0x41, 0x00, 0xC1, 0x81, 0x40, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81,0x40, 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x00,0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80,0x41,...
