I am interfacing two RS422 devices but failing to do so. I started to monitor my device signals and fell into confusion. Please help me understand a few things. I am attaching snap 01 of my device (LTC2872) data on TX+ line measured with respect to GND.
Question 01. From LTC2872 Snap01 I get data as per theoretical concept. With data appearing in Snap02, why are there extra bits appearing here? Data length should be 1.04ms at 9600 8N1.
Question 02. Why are the voltage levels of both devices different? How do I match this level?
P.S: Differential Signal (A-B)
Differential Signal measured A w.r.t B
