Powering the DB-24 Backplane
You can power the DB-24 Digital I/O Backplane internally
for some boards, or you can use an external +5 V power
supply. Before you attach the DB-24 backplane to the
board, you must configure it for internal or external
power.
To configure the DB-24 for internal power, remove the
socketed 1 amp fuse from the left of the +5 V dc and
GND screw terminals. Install this fuse in the socketed
position to the right of the +5 V dc and GND screw termi-
nals on the DB-24 backplane.
To configure the DB-24 backplane for external power,
ensure that the socketed 1 amp fuse is installed to the
left of the +5 V dc and GND screw terminals. Refer to
Figure 4.
Attaching the DB-24 Digital I/O Backplane
To attach the DB-24 backplane to a data acquisition or
6B50 board, use a 50-pin cable, such as the AC1585-9
cable or the CAB-03 cable (available from Analog
Devices). Attach one end of the cable to the digital I/O
connector on the board and attach the other end of the
cable to the digital I/O connector (J1) on the DB-24 back-
plane. Make sure that Pin 1 on the cable corresponds to
Pin 1 on the connector. Refer to Figure 5.
