In this video we show what is happening when a datacable or other HF signal cable is not properly terminated and

Mostly unskilled engineers nobody tries to understand termination resistors even explanations and finally get communication problems. This video is a good solution for them.👍

very nice video... this is a great bench top test that can be very useful on the factory-floor... now for my oscope and function-gen and lets get started... thanks..:)

normaly for data communication we use special wiring but in industrial sites sometimes we need to connect modbus communication on the standard wiring and then is it very important to terminate the cables with the right resistance

good video, but you have not shown it with wrong resistance, what happens if you put 200 ohms? or 500

@@EvillNooB , with wrong resistors you could have a breakdown of de shape (square waves), with the correct resistors the shape will be always good

Great video! I had to do the same. I used a regular wiring (2x 0,75mm pp) to connect two devices through rs485. Incredibly when the ambient temperature rises to about 28° C, the communication stops. I've put a 220R resistor (one at each side), and the problem was solved. The length of the cable is about 130 meters. How do I see if the resistors I used there are properly? Best

RS485! interesting. Was your termination resistor was between A and B?

Test it whit a function generator with square waves and a oscilloscope, the square waves must always have the same shape independent of the frequency , than you have the right resistor.
