By lowering the baud rate you're now allowing device B (and SERIN2) twice the time to receive the bits and assemble the byte.
That's probably what's helping a lot more than any line noise issue.
...
Tumbleweed, I had very strong suspicions that the issues were in the communication lines. I changed the Baud rate from 19200 to 9600 and I haven't got anymore wrong data at the receiver. I remember...
Ioannis, yes I'm doing data validation checks all the time. The first byte of the array is always 174. If this condition is not met, then the reading is discarded.

Hi All!
Here is the code to create a voltmeter and ammeter. Everyone has a "display of choice" so you can use this to drive whatever display you wish to add. The color coding of the wires is only as a reference to make construction easier. I understand from Allegro that the ACS758 can handle as much as 200 amps and 72 amps is about maximum for this code. Hope this is of use and helpful to others.
Re: SERIN2 Receiving Wrong Data
The sending device has the typical 18F4550 USB setup and it is set to "Define OSC 48". The receiving device is set to "DEFINE OSC 16".
