Serial port Ethernet equipment is widely used in industrial automation, rail transportation, electricity, wind and other industrial communications energy, the network port to the emergence of serial devices, some serial devices easily into the Internet communications, management and monitoring of the corresponding equipment operation. Because the serial communication in the era of underdevelopment of science and technology, or the special requirements of communication equipment can only RS232 and RS485 serial protocol exists, but with the communication speed and the rise of local area network program, to achieve serial equipment and fiber / Network communication transmission, we must use the serial server to solve the corresponding problem.
Shenzhen Zhenxin Communication Technology Company specializes in network communication equipment for more than 10 years, R & D technical team more than 20 people rich experience, has for the Huawei Emerson national computer for close cooperation. The company's products have undergone rigorous testing and inspection, and access to the great success of the market. The company's production of serial server technology in a leading position, and some technology access to the national patent, an industrial communications partners an ideal choice.
Serial server selection criteria:
Among the many manufacturers to do serial server, how to choose value for money to the serial network equipment? According to the price to distinguish between good and bad is probably not the only standard. First of all to distinguish a good or bad price of the product is an important reference point Yes, but the corresponding we also know that no good goods is not cheap goods is not cheap reason. As the buyer always wants the lowest price to buy the best product, but look back if you are producing it will be sold to you? Each industry has its own market and standards, a product worth how much money their minds can be converted to know. Sometimes the value of the brand is always more expensive than the product, so the customer wants to use the value, rather than the added value of the product.
Then how to judge good or bad to start from several aspects, one core program in the domestic market 90% of the companies will choose Taiwan, the domestic low-end chip to do, and even many are recycled second-hand chip after the re-grinding production, in order to To low-cost to capture the market, the temptation to customers. Products can not see the problem within a short time, but as industrial communications products used in the industrial environment there is a problem, which is the technical staff to get the most feedback. Communication industry technology and construction implementers are more understanding, as the company's procurement staff would like to always be the most convenient things to highlight their ability to save costs for the company, as the program's implementation is the most stable and better But also the specific responsibilities assigned to each job lead to different angles of thinking. What is the dominant thing in the end? A single-port serial server with low-end program to do, half of the old components plus all the cost to buy more than 260 yuan, the new about 320 yuan, foreign pure industrial-level program to be about 380 yuan, this standard is obvious.
The other is a stable serial server needs to use a separate chip to do, and the minimum to more than two. Ninety percent of the market is the network module to do, so the program communications department is stable, the loss of data and is intermittent. In the working environment temperature can not reach the industrial temperature -40--80 °; let alone other functions.
Second, the serial server is the most software features and configuration, many people have heard that the serial server must use serial software to work, this is not wrong. But as Zhenxin communications production of the serial server does not require virtual serial port software to operate, as long as the equipment directly and our serial server link, the device becomes a direct communication super terminal. This technology is the leading technology in the production of the serial server industry and the only owner of patent protection. At the same time Zhenxin communications production of the serial server can also be based on customer needs to use their own development of the virtual serial port software, the software without any settings can automatically identify, plug and play, is the most advanced fool-type serial server.
The company's ZP-8XXX series of serial servers in the industry's smallest fool-type serial networking equipment, but also Huawei's main product specifications are as follows:
☆ baud rate: 300bps - 115200bpsKbps (support non-standard baud rate)
Protection: built-in 2KV electromagnetic isolation anti-interference function, with Reset button, can be forced to reset when the machine crashes; built-in WDT watchdog automatically restart the timer, an output to the MCU RST side, MCU normal work, Output the signal to the feed end at a time. Clear the WDT. If the WDT timer is exceeded, a reset signal will be given to the MCU to reset the MCU to prevent the MCU from crashing. The watchdog's function is to prevent the program from dead , The signal is intermittent or the program running fly, etc., in the country as the first.
☆ the serial port server and HyperTerminal connection, no need to establish a virtual serial port can communicate directly, greatly enhance the practicality and convenience, known as the fool-type serial networking equipment, the domestic initiative; ultra-stable communication rate and small size.
☆ network protocol: ICMP, ARP, IP, TCP, UDP, DHCP, HTTP, DNS, SNMP V1 / V2c
☆ configuration options: Web browser or ezConfig search tool
☆ working mode: TCP Server, TCP Client, TCP
☆ Mixed, UDP, Real COM mode, Windows Real COM
☆ support system: Windows95 / 98 / ME / NT / 20002003/2008 / XP, Windows XP / Vista / win7 (32 \ 64) win8 (64-bit) can drive up to 1024 serial ports, in this mode, The server's serial port can be mapped to the local COM port of the Window host.
