Figure B-6. PXI-8461 Parts Locator Diagram
Connecting pins 1 and 2 of a jumper configures the PXI-8461 physical
layer to be powered externally (from the bus cable power). In this
configuration, the power must be supplied on the V+ and V– pins on the
port connector. The jumper must be in this position for the DeviceNet
interface to be compliant with the DeviceNet Specification.
Connecting pins 2 and 3 of a jumper configures the PXI-8461 physical
layer to be powered internally (from the board). In this configuration, the
V– signal serves as the reference ground for the isolated signals.
The PCMCIA-CAN is shipped with the bus power version of the
PCMCIA-CAN cable. An internally-powered version of the
PCMCIA-CAN cable can be ordered from National Instruments.
