Inserting NetLinx Cards into the NetLinx Control Card Slots

The optional NetLinx Cards can be installed horizontally into the NXF-MINI through the card slot openings on the front of the enclosure.

To install a NetLinx Card:

1.Discharge the static electricity from your body by touching a grounded metal object and unplug all the connectors from the unit.

2.Remove the three (3) screws by turning them in a counter-clockwise direction and remove the front faceplate.

3.Align the edges of the card with the internal guide slots and gently slide the card all the way in until you feel the rear edge of the card lightly snap into place.

4.Re-secure the faceplate by inserting the three (3) screws by turning them in a clockwise direction and securing the front faceplate to the NXF-MINI.

5.Re-apply power and other connections as necessary.

Setting the MINI’s Control Card starting Card Address

The 8-position CardFrame Number DIP switch, located on the lower-left rear of the CardFrame, sets the starting address (the device number in the D:P:S specification) for the Control Cards installed in the unit.

The Control Card address range is 1-3064. The factory default CardFrame DIP switch value = 0 (All CardFrame DIP switches in the OFF position).

The formula for setting the starting address is:

(DIP switch value) + Card slot Number (1-4) = Card Address For example:

For DIP switch setting, 00010101:

(0 + 0 + 0 + 96 + 0 + 384 + 1536) + SLOT #(ex:1) = 2017. A card in slot number 1 = device address 2018.

Set the CardFrame Number DIP switch based on the table below.

Position	1	2	3	4	5	6	7	8
Value	12	24	48	96	192	384	768	1536	ON
									position

Cycle power to the unit for approximately 5 seconds. This allows the unit to read the new device number settings.

Using the PSN NetLinx connector for power

To supply power from the local power supply to the rear 2-pin mini-Phoenix power jack; the incoming PWR and GND cables from the power supply must be connected to the corresponding location on the NXF-MINI 2-pin 3.5 mm mini- Phoenix connector (FIG. 3).

1.Insert the PWR and GND wires into the terminal end of the PSN 2-pin 3.5 mm mini-Phoenix cable.

2.Tighten the clamp to secure the two wires.

3.Verify the connection of the other end to the mini-Phoenix connector on the power supply.
