Dual serial port server serial port networking RS232 RS485 to network serial port to Ethernet cross network segment

Introduction：

With the advent of the era of M2M and the Internet of Things, there is an increasing demand for remote control through device networking, which has led to a rapid increase in the demand for serial servers. Of course, the price must return to a reasonable level. The era of violence that used to cost a few hundred yuan is over, and a reasonable price wins by quantity,.

Product Features:

Industrial grade - Operating temperature -40 to 85 degrees Celsius - Long term application guarantee in Gobi desert environment and computer room
10/100MNetwork interface. Maximum baud rate of serial port230400bps.
Industrial grade hardware protocol stackHigh stability and reliability.
The embedded module has a small size.2.8X4.9CM
It is easy to use Ethernet and serial portswebPerform parameter configuration.
TCPserver,TCPclient,UDP.
Support dynamicIP（DHCP）, or static settingsIPaddresssupportDNS
Support automatic polarity conversion（MDI/MDIX）. Don't worry about whether the network cable is crossed or directly connected
internal32kByteStorage asTCP/IPCommunication cache.
9-28vPower supply system.
Power consumption less than250MA.
Support serial port and485Transparent transmission to the network
Supporting the underlying sub connection mechanism of the protocol better ensures the stable and reliable operation of devices when disconnected
Support serial port and485transmissionmodbus RTUturnmodbus TCP IP(i.emodbusGateway function) supports firmware on-site upgradabilityWe can customize suitable communication protocols for customers
Support cross network segment scanning configuration (can easily read and configure parameters in case of forgetting device parameters)

Product advantages:

>The latest hardware solution----The hardware protocol stack is stable and reliable. This module is independently developed by the company, and customers only need a simple hardware connection to achieve serial port networking of their devices using this module

>Having a long-term usage record in an absolutely typical field--The customization of core modules for bank encryption equipment networking and railway data monitoring industry stability and reliability is the primary guarantee. And began to supply and serve various industries nationwide

>Fully self-developed upper computer configuration software and firmware code--Can meet different protocol requirements of customers faster and support on-site firmware upgrades of devices to solve problems more quickly. The upper computer provides source code

>Cross network segment configuration parameter function----It allows us to configure the network without knowing the device's IP address. Saved a lot of trouble during device installation and networking process

>The most important point is legalmacaddressWe have purchased 500w valid MAC addresses, and of course, those that are not valid can also be used. However, the potential risk of causing a small probability of MAC conflicts and causing the entire system to crash is the biggest risk

>independently developedproductionWe have a professional technical team and sufficient production sources

Module application:

Railway data collection
We started supplying bank encryption equipment only for these two industries
National Network Tax Reporting Equipment - Specially designed for tax control machine manufacturers in Beijing and Chengdu based on national communication
Standard customized program
PLC networking Modbus gateway
Remote meter reading solution
lamp control
data collection
control device
Bell supporting equipment
radio and television
Temperature and humidity collection equipment
All of these involve clients from all over the country.

Module stability testing method:

1. It depends on the specific operations of crashing and losing data when he sends and receives data in extreme situations
Automatically send data after connecting the serial port and network
Try to send as much data as possible each time, of course, within the allowed network cache, such as a few hundred bytes
The sending interval must be within 100ms. If the set time is too long, it cannot be measured at all
The testing time should be at least 24 hours. Our client suggests a week
2. Will TCP transmission fake dead and be able to ping but unable to communicate
The underlying heartbeat signal should be kept alive in English, and it should not affect data transmission. It is based on the TCP link layer, which is why our device can better solve this problem. If a device uses a software protocol stack, it cannot be completely solved unless it is a self-developed protocol stack
