CR-AD3 Analog Card Description

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-AD3 analog card is used for CR-PGM Ⅲ

programmable control host’s function expansion;

it allows CR-PGM Ⅲ host to increase double

power output function, and can read actual

voltage value from the port.

Application Characteristics

◆ Input: 3 high impedance input;

◆ Output: 3 DC output;

◆ D . A, a . D conversion: A/D and D/A converter

functions can be used for sampling and control;

10 AD sampling precision, 12 output precision;

◆ Input voltage range: 0 V to +12 V;

◆ Output voltage range: -12 V to +12 V;

◆ Output voltage can be regulated by software;

◆ Maximum acceptable voltage of Input is +36

volts dc;

◆ The maximum current of each output is 5mA.

External Reference Input

◆ The Max input sampling voltage value is +12

volts DC;

◆ The over voltage is +36 volts DC;

Operation Methods

◆ Output voltage control method (D/A converter);

CR-PGM Ⅲ host send certain roads and certain

volts voltage to analog card, analog card receive

the instruction to make voltage output.

◆ Reads the input voltage ( A/D converter )

CR-PGM Ⅲhost send instruction of reading

certain road to analog card, after receiving the

instruction, analog card will feedback the actual

voltage to the CR-PGM Ⅲhost.

◆Following are the programming function

description of CR-PGM Ⅲ when use analog card

SEND_QACAR

Void SEND_QACAR (String dev,int channel)

Function: send the request of analog card voltage

value, after sending the request, will trigger the

analog card DataEVENT events, where they can

get the voltage value, specific examples to see

the BYTES_TO_INT Parameters of other

functions.

dev - :Analog device

channel - :Equipment channel number

Example:

Acar_m = M:8:ACAR; // Define host board No. 8

analog card

SEND_QACAR (Acar_m,1); // read the first

voltage value of Acar_m

BYTES_TO_INT

Int BYTES_TO_INT (byte[] b)

Function: process the first 4 bytes of byte array as

an int number, if B is less than 4 bytes, convert

according to its real bytes, big endian mode.

Returns:

Return to the converted int number.

Example: analog card voltage returns, the actual

voltage of analog card = return voltage (mV)
