4. Procedure for connecting the user system
I Connection
Before using the QFP-100P Probe Header, mount the supplied NQPACK on the user system. To
connect the header board to the adapter unit, use the flat cable (2 lines) supplied by the adapter unit
sold separately.
Refer to the hardware manuals of each adapter unit about the way to connect.
1. To connect the header board to the user system, match the first pin of the index mark (L) on
the NQPACK mounted on the user system with the index mark (L) on the header board, and
then insert it (see Figure 3).
The pin of YQPACK is thin and easy to bend. Insert NQPACK after confirm that the pin of
YQPACK is not bent.
2. Insert each header board mounting screw for header board in each of the four tapped holes
on the header board through a washer, and then first tighten the screws in opposing corners
followed by the two remaining screws (see Figure 4).
To tighten the screws, use the special screwdriver supplied with the NQPACK to finally
tighten the four screws in sequence. Tightening the screws too tight might result in a
defective contact.
