1. Serial communications BasicsSome commands do not require a data field(s)Checksum byteThe “Checksum byte” is used to detect errors during transmission or receptionChecksum byte = (projectoraddress + command bytes + Data bytes) Modulo \x100Stop byteThe “Stop byte” informs the projector (in case of transmission) or the computer (in case of reception) that the data transfer is completeand that the interpretation of the command and data bytes can start.Acknowledge (ACK)If the communication link and if the sent commands can be interpreted by the projector an “ACK” command is sent back. In case thecommands cannot be interpreted a “NACK” command is sent back.End of process (EOP)When the end of process command is activated, an EOP is send after the ACK command to signify the completion of the process.for more information about this, see the EOP command.NoteAny command byte, data byte or checksum byte that equals \x80, \xfe, \xff has to be converted !1. Transmission- instead of \x80, send \x80 followed by \x00- instead of \xfe, send \x80 followed by \x7e- instead of \xff, send \x80 followed by \x7f2. Reception- replace \x80 followed by \x00 with \x80- replace \x80 followed by \x7e with \xfe- replace \x80 followed by \x7f with \xff1.2 Data wordsmsbThe most significant byte, is the byte with the greatest weight (value).lsbThe less significant byte, is the byte with the smallest weight (value).DescriptionA word contains more than one byte, the first byte is the msb, the last byte is the lsb.Examples of data words• The projector runtime parameter is described using an unsigned double word where 2 bytes (msb ...lsb) represent the value ofthe runtime in seconds.How to calculate the value of a word ?Lets take the example of a double word returned by the “projector runtime, read” commando.6 R5976884 RLM SERIES 04/04/2006
