NXI NetLinx Integrated Controller
Product Information
The NXI NetLinx Integrated Controller represents the new generation of AMX multi-port central controllers.
The NXI can be programmed to control RS-232/422/485, Relay, IR/Serial, and Input/Output devices using the
NetLinx programming language and NetLinx Studio program. Depending on your specific control needs, the
NXI can be equipped with either a Master or Hub Card. For use as a master controller, the NXI accepts the
NXC-ME260 NetLinx Master Card.
Front and Rear Panel Components
Remove the faceplate to see the front panel (FIG. 1) containing groups of colored LED indicators that light
when their corresponding control ports receive/ transmit data. These LEDs are grouped by control type, and
are numbered according to their corresponding port (connector) numbers on the rear panel. The rear panel
contains all of the RS-232/422/485, Relay, IR/Serial and I/O connectors, plus the ID pushbutton and ICSP
LED. Figure 1 shows the front and rear panels of the NXI.

NXI NetLinx Integrated Controller
Connections and Wiring
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.
Connections and Wiring
Preparing/connecting captive wires
Strip 0.25 inch of wire insulation off all wires.
1.
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.
