1. shell, providing shielded wire interface (improving anti-interference ). Industrial-grade enhanced type: multiple protection measures such as -protection, static electricity, short circuit and reverse connection protection!2. The three terminals of USB, CAN1 and CAN2 are completely isolated, truly isolated, and do not interfere with each other! Built-in (gas discharge tube), tube and other multi- protection, effectively release instantaneous high current and static electricity. 2.0mm super thick, super PCB, immersion gold process, the stability is improved by 200%.3. All electronic components, automatic placement machine processing (), lead- process; The built-in common mode coil of can suppress common mode interference and increase the anti-interference by 10 .4. Optical inspection, 72-hour continuous transceiver calibration test, high and low temperature aging test, vibration and shock test. Each channel has two built-in 120 ohm terminal resistors, which is convenient for point-to-point debugging. Terminal resistance DIP switch control, convenient and quick.5. The two channels can reach 8500 frames per second at the same time. The two channels are independently configured and work independently without interfering with each other! The two channels can communicate with each other, which is convenient for testing and learning.type:CAN analyzercolor:RedMaterial:Aluminum alloyPackage Contents:1 x CAN analyzer1 x USB cable
