ServoSense Encoder Decoding Problem

Has anyone else had to integrate Schneider BCH2 motors (or similar) that incorporate a Servotronix sensAR encoder that use the proprietary ServoSense data protocol on RS485 onto any 3rd party control system using 3rd party servo drives?

I am having a little difficulty working out how to read and decode the encoder outputs on these motors for hooking up to non-Schneider servo drives for commutation and position and to get them running on an Aerotech A3200 SMC.

I fleetingly heard that the ServoSense protocol has user licenses available for OEM's but this is also difficult to track down.
