Which trip unit and BCM date code are configured for a 2 wire modbus system?

Issue:
Which trip unit and BCM date code are configured for a 2 wire modbus system?

Product Line:
Proxima (Powerpact P, R, Masterpact)

Resolution:
Micrologic P and H firmware needs to be 2010-AK or later in order to set the BCM ULP to 2w+ULP mode.  
Also, the BCM ULP needs to have the gray connector which will have a firmware higher than 3.x.x.  
However, if the 2w Modbus wires are jumpered between E3 and E5, and between E4 and E6, then set the trip unit mode to 4w and it will work as 2w without ULP.

Breakers shipped November 2015 and after have BCM's configured for 2w + ULP.  Date code approx. 16441 and later.
