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.  

On a BCM configured for 4w Modbus, if jumpers are placed between E3 and E5, and between E4 and E6, and the mode is set to 4w on the trip unit, 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.
