Two manuals that don't help with this specific query but
are genrally useful for RA7x drives anyway are:

EK-ORA7X-SM-002     RA7x Disk Drive Service Manual
EK-RSA7X-PG-002     RA7x/SA7x Pocket Reference Guide

About the only thing they do not list are pinouts for
an OCP. So you may be reduced to waiting for someone
with one to buzz it out. There are two variants of
the OCP - the one used in the BA200 series chassis
and the one used in the SA7x enclosure (in an array
of disk drives in a rack).
