INTRODUCTION
The Checkback Communications Module is only used in chassis that have a Checkback Module and
no SOE Module. In this case, the Checkback Communications Module is installed in the same slot that
the SOE module would have occupied. This module allows a PC to communicate directly with the
Checkback module, without having to go through the SOE module.
