WebThe termination resistors on the RS-485 bus should match the cabling characteristic impedance value, which typically is 120ohm. Having two terminations on the bus will put a 60ohm load on the bus, which is typical. In normal operation, RS-485 drivers will drive a maximum of 5V differential signal onto the bus lines, which create a P=V^2/R power ... WebIn case of an RS485 twisted pair cable this termination is typically between 120 and 130 Ω. Here is a simple schematic of how the end of the lines should be terminated: "RT" is the …
WebThe RS485 bus driver is designed to handle the DC current flow for this pair of termination resistors. If you build a small network of 3, 4, or maybe even 5 devices the driver will …
