  READ, 

   

Please connect direct RS-485 communication cable between DAEJOO DPM and computer.

 

 

2. Writing settings

You can write the setting value by using write settings.

 

Digital Write

DAEJOO DPM communication driver don¡¯t support ¡®Bit write¡¯.

 

Analog Write

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             DPM address = 1 ~ 254.

3)  ADDRESS           Don't care.

4)  Extra1                   Controller type.

6 = 6 digit DPM,

4N = 4 digit recently version DPM,

BLANK6 = display of all blank command for 6 digit DPM,

BLANK4 = display of all blank command for 4 digit recently version DPM,

BLANK = display of all blank command for 4 digit DPM,

4, ... = 4 digit DPM ( default controller ).

5)  Extra2                   Dot position. ( 0 ~ 3 : 4 digit controller, 0 ~ 5 : 6 digit controller )

6 digit DPM( 6 ) and 4 digit recently version DPM( 4N ) = don't care. ( please set 'none dot' at controller's setting )

4 digit DPM = 0 ~ 3 dot position.

   

Write example 1)

 Port:0, Station:1, Address:0000, Extra1:  , Extra2:0

The setting parameter shown above is an example of write(decimal number) to 4 digit DPM(address = 1) without dot.

 

 Write example 2)

Port:0, Station:2, Address:0000, Extra1:  , Extra2:1

The setting parameter shown above is an example of write(decimal number) to 4 digit DPM(address = 2) with 1 dot position.

 

 Write example 3)

Port:0, Station:3, Address:0000, Extra1:  , Extra2:2

The setting parameter shown above is an example of write(decimal number) to 4 digit DPM(address = 3) with 2 dot position.

 

 Write example 4)

Port:0, Station:4, Address:0000, Extra1:  , Extra2:3

The setting parameter shown above is an example of write(decimal number) to 4 digit DPM(address = 4) with 3 dot position.

 

 Write example 5)

 Port:0, Station:5, Address:0000, Extra1: BLANK6, Extra2:0

The setting parameter shown above is an example of blank write to 6 digit DPM(address = 5).

 

 Write example 6)

 Port:0, Station:6, Address:0000, Extra1: 6, Extra2:4

The setting parameter shown above is an example of write(decimal number) to 6 digit DPM(address = 6) with 4 dot position.

 

 Write example 7)

Port:0, Station:7, Address:0000, Extra1: 6, Extra2:1

The setting parameter shown above is an example of write(decimal number) to 6 digit DPM(address = 7) with 1 dot position.

 

 Write example 8)

Port:0, Station:8, Address:0000, Extra1: 6, Extra2:0

The setting parameter shown above is an example of write(decimal number) to 6 digit DPM(address = 8) without dot.

 

Write example 9)

 Port:0, Station:9, Address:0000, Extra1: 4N, Extra2:0

The setting parameter shown above is an example of write(decimal number) to 4 digit recently version DPM(address = 9) without dot.

 

 Write example 10)

Port:0, Station:10, Address:0000, Extra1: 4N, Extra2:2

The setting parameter shown above is an example of write(decimal number) to 4 digit recently version DPM(address = 9) with 2 dot position.

 

 Note) After write number to DPM, save writed number at inputed 'Station' address of WORD, FLOAT, DWORD memory.

4. Setting of DPM address and baud rate, etc

 Setting of DPM address and baud rate are as follows.

 

1) Setting of DPM address

Please press 'UP' and 'SHIFT' at the same time. Then will be displayed 'id-S'.

If you press 'SHIFT' button again, will shows 4 digit number such as '0001'.

Set DPM address 0001 ~ 0254 by using 'SHIFT' and 'UP' button.

 

 2) Setting of baud rate

After setting the DPM address such as '1)', press 'UP' and 'SHIFT' at the same time. Then will be displayed 'bA-S'.

If you press 'SHIFT' button again, will shows 4 digit number such as '0001'.

Set baud rate 0001 ~ 0004 by using 'SHIFT' and 'UP' button.

Please press 'UP' and 'SHIFT' twice. 

 

Baud rate according to number

0001 : 19200 BPS

0002 :  9600 BPS

0003 :  4800 BPS

0004 :  2400 BPS

 

3) Setting of dot position

After setting the DPM address of baud rate such as '1)', '2)', press 'SHIFT' for a while. Then will be displayed current dot position.

Set dot position by using 'UP' button.

Please press 'UP' and 'SHIFT' twice. 

   

4) Error of range over

If DPM address or baud rate range exceeds, the following will be displayed.

LOWER range over : L-Er

HIGHER range over : H-Er
