- As shown in Fig. 1-1, first, connect the personal computer’s RS-232C serial port to the 1st LCD dis
play’s LINK port and then begin to add connections from a LCD display, starting from the OUT port.
- The first & last LCD displays located at both ends of daisy chain connection must be terminated by
setting the pin 1 & 2 of DIP switch ( Set ) to ON position, located next to OUT port. For other daisy
chain LCD display(s), please keep the pin 1 & 2 of DIP switch at OFF position ( Pin 1 & 2 are
default at OFF position ).
*The new DIP switch setting requires a power cycle of LCD display to take effect.
- The MC module of LCD display will automatically assign an available ID number from 1 to 64 to
each LCD display when connected to the daisy chain, to eliminate LCD displays trying to use the
same IDs simultaneously.

1) Computer to LCD display connection standard
- Conducts bi-directional communication using serial RS232.
- Use three signal wires of TxD, ( pin 2 ), RxD ( pin 3 ) and GND ( pin 5 ), among the RS232
standard wires, as Fig. 2-1.
- Use DTR ( pin 4 ), RTS ( pin 7 ) for hot-plug detect.
- The distance between the PC computer to LCD display is limited 15m.
2) LCD display to LCD display connection standard
- Conducts bi-directional communication using CAN bus
- A maximum of 64 LCD display units can be daisy chained to one CAN bus, up to 1,000 meters.
- The distance between LCD Displays is limited 300 meters via Cat 5/ 6 cable.
3) Command communications
The CAN bus requires the MCS module of LCD display registration by sending command < 0x01 >
to add or remove the LCD display(s) from the CAN bus before command communications. Please
refer to page 6 for more details.
All communications are conducted in the form of hexadecimal number, and the checksum calculation
method as below :
Total = Command + ID + Val1 + Val2 + Val3 + Val4 + Val5 + Val6;
Checksum = 256 – Total;
* Unsigned character of Checksum, Total=0;
Get Power Status ( e.g. Power ON & ID=1 )
Here, each set functions according to the commands received and responds with ACK at the same time.
Therefore, the operation of each set should be checked after this process.
