materials and manufacture at the time of sale and will remain in good working order for a period of three (3) years following the
date of the original sales invoice from AMX. The three-year warranty period will be extended to the life of the product (Limited
Lifetime Warranty) if the warranty card is filled out by the dealer and/or end user and returned to AMX so that AMX receives it
within thirty (30) days of the installation of equipment but no later than six (6) months from original AMX sales invoice date. The
life of the product extends until five (5) years after AMX ceases manufacturing the product model. The Limited Lifetime Warranty
applies to products in their original installation only. If a product is moved to a different installation, the Limited Lifetime Warranty
will no longer apply, and the product warranty will instead be the three (3) year Limited Warranty.

All products returned to AMX require a Return Material Authorization (RMA) number. The RMA number is obtained from the AMX
RMA Department. The RMA number must be clearly marked on the outside of each box. The RMA is valid for a 30-day period. After
the 30-day period the RMA will be cancelled. Any shipments received not consistent with the RMA, or after the RMA is cancelled, will
be refused. AMX is not responsible for products returned without a valid RMA number.

AMX is not liable for any damages caused by its products or for the failure of its products to perform. This includes any lost profits, lost
savings, incidental damages, or consequential damages. AMX is not liable for any claim made by a third party or by an AMX Autho­rized Partner for a third party.

This Limited Warranty does not apply to (a) any AMX product that has been modified, altered or repaired by an unauthorized agent or
improperly transported, stored, installed, used, or maintained; (b) damage caused by acts of nature, including flood, erosion, or earth­quake; (c) damage caused by a sustained low or high voltage situation or by a low or high voltage disturbance, including brownouts,
sags, spikes, or power outages; or (d) damage caused by war, vandalism, theft, depletion, or obsolescence.

This limitation of liability applies whether damages are sought, or a claim is made, under this warranty or as a tort claim (including
negligence and strict product liability), a contract claim, or any other claim. This limitation of liability cannot be waived or amended by
any person. This limitation of liability will be effective even if AMX or an authorized representative of AMX has been advised of the
possibility of any such damages. This limitation of liability, however, will not apply to claims for personal injury.

Some states do not allow a limitation of how long an implied warranty last. Some states do not allow the limitation or exclusion of inci­dental or consequential damages for consumer products. In such states, the limitation or exclusion of the Limited Warranty may not
apply. This Limited Warranty gives the owner specific legal rights. The owner may also have other rights that vary from state to state.
The owner is advised to consult applicable state laws for full determination of rights.

EXCEPT AS EXPRESSLY SET FORTH IN THIS WARRANTY, AMX MAKES NO OTHER WARRANTIES, EXPRESSED OR
IMPLIED, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. AMX
EXPRESSLY DISCLAIMS ALL WARRANTIES NOT STATED IN THIS LIMITED WARRANTY. ANY IMPLIED WARRANTIES THAT
MAY BE IMPOSED BY LAW ARE LIMITED TO THE TERMS OF THIS LIMITED WARRANTY. EXCEPT AS OTHERWISE LIMITED

Mounting Master/Hub Cards in an NXF CardFrame

NetLinx Master and Hub Cards can be installed in the NXF CardFrame. The card mounts in a horizontal position,
through the master card slot on the rear panel of the NXF enclosure. To install a Master or Hub Card in an NXF:

1. Discharge the static electricity from your body by touching a grounded metal object.

2. Unplug all the connectors from the NXF.

3. Remove the two screws holding the front plate on the Master Card, and remove the front plate.

4. Align the edges of the card with the guide slots inside the Master Card slot on the NXF.

5. Slide the card about halfway into the slot.

6. Inside the Master Card slot on the NXF, locate the 6-pin control cable connector.

7. Plug the connector from the NXF into the 6-pin terminal on the Master 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.

Setting the CardFrame's starting address

The 8-position CardFrame Number DIP switch, located on the rear of the CardFrame (FIG. 1 on page 1), sets the starting
address (the device number in the D:P:S specification) for the Control Cards installed in the CardFrame. The address
range is 12-3060. The formula for setting the starting address is:

(DIP switch address x 12) + Card slot Number (1-12) = Card address

For example:

For DIP switch setting, 00010101: (0 + 0 + 0 + 0 + 96 + 0 + 384 + 1536) + SLOT #

(ex:1) = 2017.

A card in slot number 7 would be device address 2023.

1. Set the CardFrame Number DIP switch based on the information listed in the table below.

can be powered via the Master Card (default) or by an external power supply
connected to the CardFrame's PWR connector. If a power supply is connected to the
PWR connector, the CardFrame power automatically switches to the connected
power supply. In that case, the Control Cards and CardFrame are independently
powered. A simple rule to follow is that if the CardFrame contains eight or more
Control Cards, use two 12 VDC power supplies.

switch address range is 1-3072.

Position 12345678
Value 12 24 48 96 192 384 768 1536

2. Cycle power for approximately 5 seconds, so the system can read the new device number settings.

Factory default DIP switch value = 0 (zero) (All DIP switches are in the OFF position).

Device:Port:System (D:P:S)

A device is any hardware component that can be connected to an AXlink or ICSNet bus. Each device must be assigned a
unique number to locate that device on the bus. The NetLinx programming language allows numbers in the range 0­32,767. Device 0 refers to the local Master; numbers greater than 32,767 are reserved.

NetLinx requires a Device:Port:System (D:P:S) specification. This D:P:S triplet can be expressed as a series of
constants, variables separated by colons, or a DEV structure. For example:

STRUCTURE DEV
{
INTEGER Number // Device number
INTEGER Port // Port on device
INTEGER System // System the device belongs to
}

The D:P:S notation is used to explicitly represent a device number, port and system. For example, 128:1:0 represents the
first port on device 128 on this system. If the system and Port specifications are omitted, (e.g. 128), system 0 (indicating
this system) and port 1 (the first port) is assumed. Here's the syntax:

NUMBER:PORT:SYSTEM

where:

NUMBER: 16-bit integer represents the device number
PORT: 16-bit integer represents the port number (in the range 1 through the number of ports

SYSTEM: 16-bit integer represents the system number (0 = this system)

on the Controller or device)

NXS-NMS NetModules

The NXS-NMS NetModules (FG2009-10) accommodate one NetLinx Control Card, and connect to the NetLinx bus via

ICSNet connections. The NetModules offer a simple and economical way to integrate additional functionality to control
systems. FIG. 2 shows a NetModule shell and its main components.

Mounting modules into an equipment rack

To install the modules in an equipment rack using the optional AC-RK kit:

1. Remove the front faceplate from the module to expose the mounting holes.

2. Mount the module on the AC-RK bracket.

3. Place the AC-RK bracket (with the module) in the equipment rack and secure the bracket to the rack.

4. Replace the front faceplate on the module, and attach the translucent plastic cover to the faceplate (if necessary).

Installing Control Cards into an NXF CardFrame

1.

Remove the magnetic front faceplate/viewing window from the CardFrame.

2. Align the edge of the Control Card with a slot in the CardFrame. Slide the card into the CardFrame and press until

you feel the Card seat in the backplane connector.

3. Put the magnetic faceplate back on the CardFrame. Secure with mounting screws (if 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.

3. Tighten the screws to secure the wires in the connector. Do not tighten the screws excessively; doing so may strip

the threads and damage the connector.

Using the ID button

The ID Button on the rear panel of the NetModules (see FIG. 2) is used in conjunction with the NetLinx Studio software
program to allow you to assign new Device and System numbers for the Module.

1. Using NetLinx Studio, place the system in Identity (ID) Mode. ID Mode means the entire system is put on hold

while it waits for an event from any NetLinx device in the named system (for example, pushing the ID button on a
Module). The device generating the first event is the identified device.

2. Press the ID Mode button to generate an event from the Module and allow you to assign new Device and System

numbers in NetLinx Studio.

An ICSNet port on a NetLinx Master or Hub supplies up to 500 mA at 12 V for module
power.
