10 Terminating and Mounting Room Bus Connectors for NI-series Modules
For the NI-series modules, ensure that each room bus cable is identified and properly terminated with an 8-
pin block connector (NICT-8AA). The following figure shows the correct pinout for terminating the active
room bus cables.
Figure 12. 8-pole connector (NICT-8AA) for active room bus connections
Optionally the 8-pin block connector (NICT-8CA) can be used.
Figure 13. 8-pole connector (NICT-8CA) for active room bus connections
The 8-pole connectors (P/N NICT-8AA or NICT-8CA) are not included and must be ordered
separately.
Caution: Because of the larger size of the NICT-8CA block connector, it will collide with the
wire holding clips of the NIRC4-xMN housing. Take proper measures to avoid collision by
removing (cutting) the wire holding clip from the base.
