e 1000 e F ( AC Termination H T G N AC termination is used to reduce the power consumption of E L E idle links as well as to reduce ringing voltages. The negative L B 100 A effect though is a reduction in cable length and bit rate. A C resistor and capacitor can be placed in...
Essential for minimizing reflections are termination resistors that match the cable's characteristic impedance. Common RS-485 cables (a twisted pair of 24AWG wires) should be terminated with a 120Ω resistor at both ends.For more about RS-485 designs, refer to Methods for Trimming the Power ...

(-50mV to -200mV) that complies fully with RS-485 specifications while guaranteeing that a 0V input produces a logic "High" at the receiver. The remaining termination resistor (approximately 200Ω) is connected between the differential lines. By eliminating the 330Ω pullup and pulldown ...
Many signal integrity and communication issues with RS-485 networks stem from terminations, either from a lack of termination or improper termination. In this installment of the RS-485 basics series, I’ll talk about when you can get away without terminating yourRS-485network, and if you need...
如果无法避免星型配置,可以使用特殊的RS-485中继器,在每个跨上双向侦听数据,然后将数据重新传输到所有其他跨Typical bias network together with termination. Biasing and termination values are not specified in the RS-485 standard.Ideally, the two ends of the cable will have a termination resistor connected...
