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 fou

Projector Control 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. 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 err

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
