4. Procedure for Connecting to the User System
Before using the MB2198-304, mount the supplied NQPACK on the user system.
Connect the header board directly to the adapter. Refer to the operation manual of the adapter for
details on how to connect the adapter.

Connecting
1. To connect the header board to the user system, align pin 1 indicated by the index mark (
▲
) on
the NQPACK mounted on the user system with the index mark (
▲
) on the header board and then
insert it (See Figure 3) .
The YQPACK pins are thin and easy to bend. Check that the YQPACK pins are not bent before
inserting it into the NQPACK.
2. Insert each of the screws for securing the header board through a washer and into each of the four
holes in the header board. Partially tighten one of the screws with the special screwdriver supplied
with the NQPACK and then partially tighten the screw in the diagonally opposite corner. Partially
tighten the two remaining screws. Finally repeat the process making the screws equally tight.
(See Figure 4) .
Take care not to overtighten the screws as this may cause a faulty connection.
