2.3. WEB introduction and configuration

The module supports web page configuration. Users can input the IP address and port through any browser (the

default IP address is 192.168.4.101. The browser default port is 80). After successful login, enter the web page (the

default username and password are both admin).As shown in the figure:

Chengdu Ebyte Electronic Technology Co.,Ltd E810-DTU(CAN-ETH) User Manual

Select a page for parameter browsing and configuration according to specific needs (taking CAN settings as an example).

After the parameters filled in correctly in this page, click Save Settings.

The page will automatically jump to the module management page. After clicking on the module to restart, the module

will restart and the parameters set will take effect.

2.4. Communication instructions

Preparation:

One E810-DTU(CAN-ETH), one CAN analyzer(This is used to analyze, send and receive data on CAN bus. One side of

the CAN analyzer is CAN-Bus and another side is USB, which can connect to computer directly), E810-DTU(CAN-ETH)

is connected to the CAN_H,CAN_L of CAN analyzer to form the communication network. In a same one PC, the mutual

communication can be realized via the CAN analyzer and network debugging tool.

2.4.1. SOCKET instructions

1. Set the IP address of PC same as the E810-DTU(CAN-ETH) and same subnet mask. For example, the IP of PC is

192.168.4.100, the IP of module is 192.168.4.101;

2.4.2. TCP Client instructions

1. Open the network debugging assistant in PC, here We take “Savage Network Debugging Assistant” as example.Set the

protocol type to TCP Server. The local IP address and port are set to 192.168.4.100 and 8886 respectively.

Chengdu Ebyte Electronic Technology Co.,Ltd E810-DTU(CAN-ETH) User Manual

2. Set the network type of SOCKET A1 to TCPC (TCP Client), target IP as 192.168.4.100. local port as 0(random port),

target port 8886, click Save.

3. Open the CAN analyzer software, select the correct COM port and baud rate, and connect the device to TCP Server

for communication test with "network debugging assistant"

The below picture shows a standard data frame sent by the network. The CAN sending ID is 0x00 0x00 0x00 0x00 0x01

and the data is 0X11 0x22 0x33 0x44 0x55. The data sent should conform to the data format (see the basic function of

CAN-Data Protocol for details).

2.4.3. TCP Server instruction

1. Set the Network Debugging Assistant to TCP Client, set the remote host IP to 192.168.4.101, and set the remote

host port number to 8886.
