  • Page 3: Setting Up

    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...

  • Page 4: General

    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.

  • Page 5: Message Body

    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...

  • Page 6: Command Return Codes

    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.
