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

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 different function types:
Function type
Execute
Comments
An execute function executes an action on the projector, i.e.
only one state.
State
A State function performs a set operation from a predefined
list of states. Not all values in the range
have to be legal.
State String
Adjust
As state but returns ASCII strings
An adjust function is characterized by Maximum >
Minimum. And all the integer values between Minimum and
Maximum are legal.

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
0xBE
Byte 1
Magic Number
0xEF
Byte 2
0x80
Byte 3
Body size
0x06
Byte 4
0x00
Byte 5
Byte 6
CRC
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.

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:

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
ACK
Return Code Value
0x06
Description
Packet acknowledged – no errors. Normal
response when receiving
NAK
ERR
0x15
Packet not acknowledged – some error occurred in
receiving this packet. Usually
Indicates a CRC error.
Packet was received OK, but an error occurred
when executing the command contained in the
Packet. The two bytes following the 0x1C
(0xXXXX) are the error code
0x1C 0xXXXX
VAL
0x1D 0xXX 0xYY
Strings 0x06
Packet value returned. This return code will be
sent in response to a Operation packet of type
OPERATION_GET. The first byte after 0x1D
(0xXX), is the least-byte of the returned value. The
0xYY is the most significant-byte of the returned
value.

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.
// nCount : Number of data bytes.
// Return: 16-bit CRC value.
WORD CalculateCRC16 (BYTE *pcData, int nCount)
{
BYTE cCRCHi = 0xFF; // high byte of CRC initialized
BYTE cCRCLo = 0xFF; // low byte of CRC initialized
BYTE cIndex; // will index into CRC lookup table
while (nCount--) // step through each byte of data
{
cIndex = cCRCHi ^ *pcData++; //
calculate the CRC
cCRCHi = cCRCLo ^ cCRCHiArray[cIndex];
cCRCLo = cCRCLoArray[cIndex];
}
return (cCRCHi << 8) + cCRCLo;
}
