3ASC25H219B DATX133 Detailed explanation of CAN bus technology

Abstract: Bosch introduced a new type of serial bus - CAN Controller Area Network - at the SAE (Society of Automotive Engineers) conference, which was also the time when CAN was born. Today, almost every new bus in Europe is equipped with a CAN local area network. Similarly, CAN is also used for other types

3ASC25H215E DATX131 Exploring the Main Content and Key Projects of LTE Terminal RF Testing

Abstract: With the rapid growth of wireless data services, the continuous introduction of new air interface technologies, and market competition from WiMAX, UMTS faces challenges in supporting real-time data services and large data volume services, and needs to evolve continuously. LTE has the characteristics of flexible spectrum usage, seamless interoperability with existing technologies, and low

3ASC25H214 DATX130 Five questions you have to know about 5G technology

Summary: According to reports, people who are obsessed with technology are generally speed and performance enthusiasts, who love high-speed processors, large memory, and flying network connections. But from the current technology perspective, it is unlikely that there will be significant improvements in processors and storage, but network speeds are different because 5G is already on

3ASC25H204 DAPU100 NFC technical specifications and testing requirements

Non contact point-to-point data transmission (within ten centimeters) between electronic devices for data exchange. This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID, mainly used for providing M2M (Machine to Machine) communication in handheld devices such as mobile phones. Due to the natural security of near-field communication, NFC technology

Construction specification requirements for grounding

1. The shell, instrument panel, cabinet, box, box, cable tray, protective tube, bracket, base, and other normally uncharged metal parts of electrical instruments that may carry dangerous voltage due to insulation damage should be protected and grounded. For local instruments, switches, etc. with a power supply voltage not exceeding 36V, protective grounding may not be

The Method of Reducing Soil Resistivity by Grounding DCS System

1. Change the soil structure around the grounding body. Within a range of 2-3 meters of soil around the grounding body, adding substances that are not suitable for water and have good water absorption, such as charcoal, coke cinder, or slag, can reduce the soil resistivity to 1/5-1/10 of the original value. 2. Use salt

DCS system grounding method

1. Starting from firmware version V4.1, the S7-1200 CPU supports configuration control functions, making module configuration and installation more flexible. 2. Establish a dedicated and independent grounding network for the DCS system; 3. Set up a dedicated grounding network for DCS, which is connected to the electrical grounding network through a grounding wire. Due to

Detailed analysis of DCS system grounding

1、 Basic requirements for DCS system grounding DCS system grounding is to ensure that when there is a problem with the signal, power supply, or DCS system equipment entering the DCS system, the effective grounding system can withstand overload current and quickly introduce the overload current to the ground. The grounding system can provide a
