< >B Serial Network Converter
< >< . Product Introduction
< >
B is a data protocol converter (dedicated to Internet data communication). It provides R to network and Network to R data transmission, it will transparently transmit the data received from the R serial port of the converter to the data server on the network, and the data sent by the data server will be transparently sent to the R on the converter through the network. on the serial port. In other words, as long as the serial ports of the two Bs are connected to different computers or serial devices, and the network ports are connected to the Internet, different computers or devices can communicate through r.
The B provides an Ethernet interface upwards and a standard R (or serial port, communication buffer) downwards. Communication parameters can be set through software, and the baud rate ranges from b to b. B can be applied to various network environments. Network parameters and serial port parameters can be set using B setting software, or can be set by user programming.
B is divided into two types:
Type (B), this model is mainly used for the master station, such as Operation control center, the equipment connected to it is generally a computer
Type B (), this model is mainly used for slave stations, such as remote terminals, and the equipment connected to it is generally the user's equipment, on-site instruments and meters, etc.< br/> < .Network related parameters
The current address of B. When B is connected to a certain subnet, it needs to allocate the corresponding gateway according to the network segment of the subnet: the gateway of the subnet that B is currently connected to. Address subnet mask: Set the acquisition method according to the actual situation of the subnet: B's acquisition method supports manual and automatic methods. In manual mode, the user can set the address. At this time, B's own address is the address set by the user. In automatic mode, B obtains its own address through the protocol. At this time, there must be a server in the network. If the acquisition method fails, the set address is used. Communication method: B. Protocol, support and target used for network communication: B is working method, the target must be set to be the server. This value defaults to our company's server. If the user does not have his own server, he can use it for free (when the volume is small) or rent our company's server (when the volume is large). In this case, this value does not need to be Change the target port: Specify the port used by B to communicate with the target host. This value defaults to our company's server port. If the user does not have his own server, he can use it for free (when the amount is small) or rent our company's server (when the amount is small) time), this value does not need to be changed at this time. Target port: Specify the port used by B to communicate with the target host. This value defaults to our company's server port. If the user does not have his own server, he can use it for free (in small quantities) or If you rent our company's server (large quantity), this value does not need to be changed at this time. < .Serial communication related parameters
Baud rate: B serial port communication rate, the user must set it to be consistent with his machine or terminal device. B supports multiple baud rates, from b to b. Data bits: In serial port asynchronous transmission, the number of data bits actually contained in a set of data. B supports the data bits of B. This parameter should be connected to the data bits of the device connected to the B serial port. Have the same value. Normally, it is bit verification: B serial port data verification mode, which is divided into three types: none, even, and odd. The user must set it to be consistent with its machine or terminal device. Stop bit: In serial port asynchronous transmission , the number of bits in a group of data used to represent the end of this group of data. Supports stop bits and stop bits. This parameter should be the same as the stop bit of the device connected to the B serial port. Generally, it is the maximum buffer time of the bit: B slave After the serial port receives the data, it first caches the data. After the data retention time exceeds, if the next data has not been received from the serial port, B will send the received data to the maximum cache byte on the network: When B receives this amount of data from the serial port, it sends the data to the network. B sends data to the network when one of the two conditions of data retention time and data retention number is met <.
