After a conversation with Jonard at Customer Support sends the task on here. I looked at that drawing, but I don't understand if those resistors should be included or not. I don't know what voltage level those pulses should be with. There is talk of high and low level, but in our case it should be 3. Without this resistor, the voltage level appears to reach half of the total voltage when no messages are sent. The scope shows that the signal is reduced without these resistors. All this gives rise to several questions. The first question is whether it is correct with both pull-ups.

In some cases, the data may have been simplified to remove proprietary detail while maintaining critical interface geometric detail for use by customers. It is possible you are not spraying Rs resistors into the pots correctly. Brumby Supporter Posts: Country:, rs resistors.

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.

If you don't add terminations in shorter buses you may not need to the bias resistors are going to bias the bus close to VCC on A and GND on B - it really doesn't matter if you put it outside the series resistor or not because each node is only drawing uA of current.
