Teach you to configure DTU dual channel communication

Connect a dual Hub server demo configuration for that WCTU

TCP mode Dual Center data transfer

Example description

This instance uses TCP mode to forward the data received by the serial port to the server and forwards the data sent by the server to the string. Data is not encrypted during transmission.

Configuring the server network

1. Confirm the external IP address or domain name of the native server

A, the IP address for the fixed IP leased line outside this instance is 220.160.156.233.

B, if the external network is a dial-up method, you need to use the domain name.

Condition One:

Through the peanut shell or other domain name resolution terminal bound external network IP

Condition Two:

If it is only a short time test communication, you can use the current extranet IP directly

Query the current extranet IP method: Search "IP" with Baidu

If there is a network through the router server can also be logged on the router, query the running state of the WAN Port current external IP

The IP addresses that are obtained are consistent if the inconsistency may have been translated by the carrier's internal network NAT and cannot be used as a server network.

2. Confirm the network structure of the server intranet, if the server is through the router Sisu network, please do port mapping or DMA on the router.

The port mappings made by this instance are as follows:

Example one:

Query the native server intranet IP as follows:

Windows7 system, Start > Control Panel > Network and Sharing Center > change adapter settings

Right-click Local Area Connection > Status > Details

3, if there is a router Sisu network, please confirm whether the firewall above the router open this port.

4, if a firewall is installed on the server PC, make sure the firewall is open for this port.

Device parameter Configuration

Open the Configuration tool: Open and debug serial port connected to the string number, baud rate, data bits, stop bit, flow control is the default value, the right prompt to open the serial port successfully power on the device, if the device has been powered, please re-power the device.

The configuration status is successfully entered after re-power on:

Configure the Hub server

Communication test

Device connection

Restart the device and let the device connect to the server. When the device status light is blue and the device information is displayed on the server, the device is connected to the server. As shown in the following:
