XBP24CZ7UIT-004 (S2B) vs XB24CZ7UIT-004 (S2C) pin drop problem

Hi Digi

WE are using Digi product XBP24CZ7UIT-004 (S2B) in our product. When we replace this module with XB24CZ7UIT-004 (S2C) we got problem of receiving data, module does not respond after power up. It only respond once we reset it via command or via hardware reset.

I think both module are pin to pin drop compatible , please confirm.

With respect to VCC, GND, DI and DO, that is correct. They are pin for pin compatible.
