APPENDIX A: FF-8070 WIRING
The connections to the FF-8070 are all accomplished via 10 conductor ribbon cable. There are two
cables provided, one for the power/audio (connects P3 on the DVR to P25 on the FF-800) and one
for SPI communications (connects P5 on the DVR to P7 on the FF-800). The only remaining
connection is that of a back-up battery to P2 of the DVR.
For external connections, use shielded or twisted pair cable along with the provided housings and
crimp pins. Cut the cable to the shortest possible length and strip back the outer sheath 1 inch.
Unravel the braid and twist together as shown below and remove the foil inner shield (if present).
1"
Solder hook-up wire here
Solder a short piece (1 or 2 inches) of hookup wire to the shield as shown above and cut off the
remainder of the shield. Cut this wire even with the others and trim 0.1" of insulation from the end
of each wire. Using a pair of needle-nose pliers, crimp the exposed conductor into a molex pin as
shown at (1) below. Apply a small amount of solder to establish a good connection. If too much
solder is applied, it could wick down to the end of the pin at (4) -- this will make the pin difficult to
insert and it may not retain properly. If this occurs, the pin should be discarded and another
installed in its place. After all pins are secured, crimp at (2) around the insulation for strain relief.
Molex housing
Molex pin detail
The shield wire should connect to the GND connection of the specific housing. When inserting the
pin into the housing, be sure that the contact loop at (3) is oriented toward the tabs on the housing
as shown above.
