Figure A-3. Screw Terminal Block Pinout
All of the signals on the screw terminal block provide a direct connection
to the 9-pin DSUB. Pins 2 and 4 of the J2 screw terminal block provide an
alternate connection to the fieldbus. The screw terminal block is not a
second, independent link. National Instruments provides the Power+ and
Power– connections as passive connections from the DSUB to the screw
terminal. The PCMCIA-FBUS itself does not supply power to or draw
power from these pins.
