If you want to know the detail DCON protocol, please check it from CD or web CD path:\\napdos\7000\manual\
Web: ftp://ftp.icpdas.com/pub/cd/8000cd/napdos/7000/manual/

Module test and configuration

Step 1: INIT switch Operation

Find out the INIT switch( back of the module), and turn to INIT.

Reboot the module

Step 2: Install & Run DCON Utility

Please Install DCON Utility first
You can find the software on the CD.
CD-path: <Driver>:\napdos\driver\dcon_utility\
Weblink: http://ftp.icpdas.com/pub/cd/8000cd/napdos/driver/dcon_utility/
Run DCON utility

Step 3: Set search configuration & search module

Click “COM Port”

Assign the communication information and click “OK”

Module Default Setting

COM Port Refer converter Port Number

Baud Rate 9600

Protocol DCON for I-7000
Modbus RTU for M-7000

Parity Option N,8,1
Click “Search” and select “Start Searching”
The software will search the modules from COM Port

Click “Search“ and select “stop searching”
Manual stop when the modules searched

Note:
When no module can be searched, please check the wire and communication information

Step 4: Select Module for testing and configuration

Step 5: Configuration Settings & Channel Settings

Step 6: Change to normal mode and keep the settings

Turn the INIT Switch to Normal.
Reboot the module

Trouble Shooting

Q1. How to do when forgot module address or baud rate?
Please turn to INIT mode, and run DCON Utility to search.
The module supports DCON protocol at the INIT mode.
And the address is 0. The communication setting is “9600,N,8,1”.
Q2. How to configure the I-7000 and M-7000 modules?
ICP DAS provide DCON Utility to configure I-7000 and M-7000 modules.
Please download the last version from: http://ftp.icpdas.com/pub/cd/8000cd/napdos/driver/dcon_utility/
Q3. How to measure the current?
I-7018(R)(BL)(P) and M-7018(R) require optional external resistance (125Ω) for current measurement.
Please refer wired connections diagram.
And then select a suitable input range by DCON Utility.
Q4. What is the CJC function?
CJC (Cold-Junction Compensation) offset is for the temperature measurement.
You can set a CJC offset for all channels or different channel in DCON Utility,

Q5. How to programming with I-7000 or M-7000 by C#, VB, VC?
ICP DAS I-7000 and M-7000 series both support DCON protocol. And Only M-7000 series supports Modbus protocol.
For DCON protocol, please download SDK and Demo from: http://ftp.icpdas.com/pub/cd/8000cd/napdos/driver/dcon_dll_new/
For Modbus protocol, please refer this web link: http://www.icpdas.com/products/PAC/i-8000/modbus.htm
