The DBX card is an expansion card of memory. See
It adds an
additional 1 MB SRAM to the Coral main control. The card is equipped with an
extension connector on its top side allowing for another DBX or MAP/CLA card to be
connected on top of it.
The MEX-IP2 supports up to two DBX cards.
The DBX cards use a lithium battery to operate. When the battery voltage is low, the
diagnostic software displays a warning message, stating that the battery of either the
upper or the lower memory card needs to be replaced. The DBX connected directly to
the MEX-IP2 is the “lower” memory card, while the DBX connected on top of the first
one is referred to as the “upper” memory card. Up to four DBX cards can be mounted
onto a main control processor MEX-IP2 card.
Before installing the MEX-IP2 card, verify that the battery insulator between the top
contact of the battery and the battery holder has been removed on both the MEX-IP2
battery and the battery of any DBX baby card installed on the MEX-IP2 card.

General Information
Once the system database has been installed, the position of DBX cards
(“upper” and/or “lower”) on the MEX-IP2 card must not be changed.
Doing so will cause the Coral system to malfunction.
