It helps to understand your problem even though not entirely. It would be ideal for me to know which voltages do you measure across the resistors. If you have the actual board from the customer, it would be great to recreate the issue and try different solutions. As a first suggestion, I would try to lower the value of the two resistors and see if the problem occurs, if not eliminate them completely. Otherwise some TVS diodes could be helpful if there are transients causing the problem; but the diodes would affect the communication in case they clamp.

We need a bit of theory here to understand why an RS network needs Bias resistors and Termination resistors in the first place. Transmission line effects often present a problem in data communication networks. These problems include reflections and signal attenuation. When a voltage is first applied to an RS line, current flows through the line even if the line wires are open. Shortly after reaching the end of the line, the current settles to a final value determined by the series resistances in line, the voltage applied, and termination. The line sees reflected voltages as the current settles if the initial and final currents vary, resulting in possible data integrity issues. If the data rate is low or cables are short, termination may be unnecessary. Both ends must be terminated since the direction of propagation is bidirectional. With RS networks, there are periods of time when no driver is actively driving the bus. On a Master-Slave network this would correspond to potential times when the Master is not transmitting and the slaves have finished responding to any command.

This parallel resistor calculator is a tool for determining the equivalent resistance of a circuit with up to ten resistors in parallel. On the other hand, you can also check out our series resistor calculator if you want to learn about resistors in series. Prefer watching over reading? Learn all you need in 90 seconds with this video we made for you :. A parallel circuit is characterized by a common potential difference voltage across the ends of all resistors. The equivalent resistance for this kind of circuit is calculated according to the following formula:.
