Hi,
Your new unit contains a printed circuit board with Hardware Version 3.1. This hardware includes modified RF circuitry that complies with the latest FCC rules for the U-NII-3 (5.8 GHz) band. The new hardware is in ODUs with these "B" suffix part numbers:
- C050067B001B
- C050067B003B
- C050067B004B
- C050067B006B
- C050067B007B
- C050067B009B
- C050067B010B
- C050067B012B
Release 02-60 is the oldest release that supports this new hardware.
As you probably figured out, the License Key sets a minimum version of 02-60, and 01-46 for PTP 650 compatibility.
There's more on this here: What is the difference between A suffix and B suffix in 4.9 GHz to 6.05 GHz PTP 670?
