DS-3700-4A/6A Communication Driver

DS-3700-4A/6A Communication Driver is the driver to communicate with electronic display board controller of D&A Analogtec in Korea.

1. Read settings

<Figure 1> is read setting example of  DS-3700-4A/6A communication driver. 

<Figure 1>  Read setting example of  DS-3700-4A/6A communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.

Also you can set 'delay time of write packet' (mSec unit, default = 10) by using option part.

2. Writing settings

You can write the setting value by using write settings.

Digital Write

DS-3700-4A/6A communication driver don't support bit write.

Analog Write

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             DS-3700-4A/6A controller station number = 0 ~ 31.

3)  ADDRESS           Don't care.

4)  Extra1                   Controller type of DS-3700 = 4A(default), 6A.

5)  Extra2                   Decimal point = 0 ~ 3.

0 : don't use decimal point,

1 : 1 digit decimal point,

2 : 2 digit decimal point,

3 : 3 digit decimal point.

Write example 1) 

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

The setting parameter shown above is an number write example of DS-3700 4A model without decimal point.(station number = 1)

Write example 2) 

PORT : 0 ,  Station:3,  Address:0000,  Extra1:  ,  Extra2: 1,

The setting parameter shown above is an number write example of DS-3700 4A model with 1 decimal point.(station number = 3)

Write example 3) 

PORT : 0,   Station:10,  Address:0000,  Extra1: 6A,  Extra2: 2,

The setting parameter shown above is an number write example of DS-3700 6A(6 digit number data display) model with 2 decimal point.(station number = 10)

Note) DS-3700-4A/6A controller station number can set by using Dip switch 1 ~ 5.

Setting example) 1 ~ 5 Dip open : station number = 0,

 1 ~ 5 Dip short : station number = 31.

Note) DS-3700-4A/6A controller's decimal point can set by using Dip switch 6, 7, 8.

Dip 6 short = 1 digit decimal point,

Dip 7 short = 2 digit decimal point,

Dip 8 short = 3 digit decimal point,

Dip 6, 7, 8 open = don't use decimal point.
