Caution
The system shall be mounted in an ATEX/IECEx-certified
enclosure with a minimum ingress protection rating of at least IP54 as
defined in IEC/EN 60079-15.
Caution
The enclosure must have a door or cover accessible only by the
use of a tool.
Wiring the NI 9866
The NI-9866 has one 9-pin male D-Sub connector that provides connections to a LIN
bus.
The port has two common pins (COM) that are internally connected to the module’s
isolated reference and serve as the reference ground for LIN signal. You can connect
the LIN bus reference ground to one or both COM pins. The port also has an optional
shield pin, SHLD, that you can connect to a shielded LIN cable. Connecting SHLD
may improve signal integrity and EMC performance in a noisy environment.
Caution
You must use a UL listed ITE power supply marked LPS with the
NI-9866.
The NI-9866 requires an external power supply of +8 to +18 V to operate. Supply
power to the NI-9866 V
SUP
pin from the LIN bus.
Note
Power on V
SUP
is required for LIN operation.
The NI-9866 pinout is listed in Table 1.
