receiver output data format NMEA-0183 is a universal interface standard developed by the National Oceanic Electronics Association for asynchronous communication of marine instrument data. It is a string consisting of ASCII characters.GPS receiver outputs GPS positioning data in NMEA-0183 standard format,The data terminal device needs to obtain the location information and time information from the NMEA0183 data stream output by GPS in real time.The G

the RS-232 Standard Serial Output serial data, the OEM board is 12 channel GPS receiver, it can track up to 12 GPS satellites at the same time and continuously track GPS satellites for fast positioning. The end user can enable the OEM board to work in the default factory status, without the need to set input statements. However, to use GPS information, you must use the output statement. 1.2 GPS-OEM board communication protocol GPS-OEM board has many

We often say that the serial port refers to the RS-232C interface, which was in 1970 by the American Electronics Industry Association (EIA) the serial communication standard jointly developed by Bell systems, modem manufacturers, and computer terminal manufacturers. Its full name is "Technical Standard for Serial Binary data exchange interfaces between data terminal de

serial communication technology is also necessary, perhaps a reader who would like to use this technology to write a PDA and computer data sharing program. This article mainly to RS232 to explain the Java serial communication technology. RS232 Communication Basics Rs-232-c (also known as EIA Rs-232-c, hereinafter referred to as RS232) is a standard for serial communications developed in 1970 by the Unit

Layer-4 and layer-7 Load Balancing details, layer-4 and layer-7 Load Balancing I. background of SLB: SLB (Server Load balancer): when multiple servers provide the same service, the Server Load balancer device has a virtual service address. When a large number of clients access the virtual service IP address from outside, the server Load balancer device distributes these packet requests to backend Servers Based on the server Load balancer algorithm to balance the load pressure on each server, thi

I. Introduction of LVSLVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. LVS is a TCP/IP-based load balancing technology that has high forwarding efficiency and the ability to process millions of concurrent connection requests.The IP load balancing technology of LVS is realized by Ipvs module. Ipvs module is the core software module of LVS cluster, it is installed in the LVS cluster a

I like reading books. After all, I am engaged in technology in the IT industry. If I don't read books or study, I may fall behind tomorrow. Since last year, I have been learning UML (United Model language). Software Engineers all know that it is called a unified modeling language or a standard modeling language. After reading a few books, I always feel that the theory is greater than practice. So, last week I saw a book named "UML object design and programming" published by Beijing hope
