Daisy Chain Communication
1.Communications setting
Set the same communication settings (selecting from options below) on the
CONTROL terminal for transmitting and receiving side connected with a RS-232C
cable.
Baud rate: 4800 / 9600 / 19200 / 38400 bps
Parity NONE / ODD / EVEN
Data bit: 8 bit (fixed)
Start bit: 1 bit (fixed)
Stop bit: 1 bit (fixed)
2.Commans available only for daisy chain
communication
The projector supports the following commands only for daisy chain.
(1) Control the projector (Set/Increment/Decrement/Execute)
(2) Get the projector’s status (Get)
(3) Get the number of connected projectors
(4) Set the communication Group identification and Communication ID.
(5) Get the communication Group identification and Communication ID.

Calculation of Checksum
Sum up all of 12 bytes except the Checksum, then make the bit inversion of the
lowest byte of the total, and add 1 to the inverted byte. The calculated result is
the Checksum data.

BE + EF + 83 + 06 + 01 + 01 + 01 + 00 + 00 + 60 + 01 + 00 = ‘029AH’
The lowest byte of ‘029AH’ is ‘9AH’ (1001 1010). Making the bit inversion of the
‘9AH’ gets ‘65H’ (0110 0101), then, add 1. The calculated checksum is ’66H’.
