Installing the Master or Hub Card
The NXC-ME260 NetLinx Master or any Hub Card can be installed in the NXI. The card mounts in
a horizontal position, through the master card slot on the rear panel of the NXI enclosure (see
FIG. 1 on page 1).
To install a Master or Hub Card in an NXI:
1. Discharge the static electricity from your body by touching a grounded metal object.
2. Unplug all the connectors from the NXI.
3. Remove the two screws that hold the front plate on the Master or Hub Card, and remove the
front plate.
4. Align the edges of the card with the guide slots inside the Master Card slot on the NXI.
5. Slide the card about halfway into the slot.
6. Inside the Master Card slot on NXI, locate the 6-pin control cable connector.
7. Plug the connector from the NXI into the 6-pin terminal on the Master or Hub Card. This
connector is keyed to ensure correct orientation.
8. Once the control cable is connected, gently slide the card all the way in until you feel the rear
edge of the card lightly snap into place.
9. Re-apply power and other connections as necessary.
Preparing/connecting captive wires
1. Strip 0.25 inch of wire insulation off all wires.
2. Insert each wire into the appropriate opening on the connector according to the wiring
diagrams and connector types described in this section. Do not tighten the screws excessively;
doing so may strip the threads and damage the connector.
