Modbus.h Questions

Hello,

I am using the Modbus.h script to connect to my clients system. He said he can not connect and asked the following questions, this is beyond me, I didn't make any customizations so maybe someone knows these answers.

Is it using RTU(binary) or ASCII(string) format?

Also – High/Low or Low/High bit order?

Any help would be awesome,
Thank you.
