Power off the Main cabinet and remove the NTCPU card.
Included with the DSPDB are four spacers. Install one spacer in each corner of the daughter
board. Make sure to attach the spacers from the back of the daughter board so when installed,
the compact flash slot is facing up.
Position the daughter board over the CN10 connector on the NTCPU. Push the board into the
connector on the NTCPU. Gently push the corners of the daughter board down so the spacers
lock into the NTCPU.
To remove the daughter board, use pliers to squeeze the top of the spacers together, then
gently pull the daughter board off.
