CR-DA012 Data Control Card Specification

Functional Overview

The expansion card is according to the actual

needs of users; is mainly used to increase host’s

extra functions, so as to achieve the user’s

personal needs.

CR-DA012 data control card is used for CR-PGM
Ⅲ programmable control host’s function
expansion; it allows CR-PGM Ⅲ host to increase

8 roads output of adjustable voltage, easy to

control the peripheral equipments.

Application Characteristics

◆ Output: 8 DC output;

◆ D . A conversion: D/A converter function, 12

output precision;

◆ Output voltage range: 0 V to +12 V;

◆ Output voltage can be regulated by software;

◆ The maximum current of each output is 2mA

Operation Methods

◆ Output voltage control method (D/A converter);
CR-PGM Ⅲ host send certain roads and certain

volts output voltage to analog card, analog card

receive the instruction to make voltage output.

◆Following are the programming function
description of CR-PGM Ⅲ when use analog card

SEND_ACAR

void SEND_ACAR(String dev,int channel,int val)

Function: to control the voltage output of analog

card

Parameters:

Dev - : Analog device

Channel - : Equipment channel number

Val - : Value of Analog (Note: according to

specific external equipment.) (General values

range from double 0V to 12 V).

Example: acar_L = L:7:ACAR:192.168.1.20; //

Define ACAR equipment whose CRLINK ( CAN )

number is 7

SEND_ACAR( acar_L,1,12);// to send analog

value +12 to the first way of lilt_L, namely setting

analog card output +12 V
