< 1.1 > Connection

- 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 dais y chain connection must be term inated 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 switc h 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 MCS m odule 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 elim inate LCD displays tr ying to use the same IDs simultaneously.

1) Computer to LCD display connection standard

- Conducts bi-direction al 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 conn ection standard

3) Command communications

- Conducts bi-direction al communication using CAN bus

- A maxim um of 64 LCD display units can be dais y chained to one CAN bus, up to 1,000 meters.

- The distance between LCD Displays is limited 300 meters via Cat 5/ 6 cable.

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 com mand com munications. Please refer to page 6 for m ore details.

All communications are conducted in the form of hexadec imal number, and the checksum c alculation method as below :

Total = Command + ID + Val1 + Val2 + Val3 + Val4 + Val5 + Val6; Checksum = 256 – Total;

* Unsigned character of Chec ksum, Total=0;

Get Power Status ( e.g. Power ON & ID=1 )

Here, each set functions according to the com mands received and responds with ACK at the same time. Therefore, the operation of each set s hould be checked after this process.
