GR4x to GR64 Migration Guide

Product Comparison
This section compares the GR64 with its predecessor GR47/48 products, since these
are the product that the GR64 was intended to most closely replicate. For all
practical purposes the comparisons also reflect the similarities and differences to the
GM47/48 since these products are merely a subset function of the GR products.
Comparison is made from an electrical signal, functional behavior, software and
mechanical perspective. A signal interface table identifies the proposed pin out and
signal assignment. A subsequent chapter reveals specific features of those signals
which are different in the GR64 implementation, and also provides generalized
information.
Mechanical drawings help the integrator to recognize differences in the basic profile
of the products, the GR64’s variant configurations, and inspect the mechanical
mounting arrangement to confirm drop-in compatibility.
