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
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.

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.

NXC-I/O10 Input/Output Control Card
The NXC-I/O10 Input/Output Control Card (FG2021) provides 10 Input/Output channels and LED feedback. It acts as a
logic-level input and responds to switch closures or voltage level (high/ low) changes. The Switch (SW) and Voltage
(VO) modes are set with on-board jumpers. FIG. 4 shows the I/O10 card.
The I/Os on this card are not dry closure; they are electronic switches that float at 5V
when Off. Therefore, they should not be expected to work in situations that require
true dry contact (or dry closure).
The I/Os do work with AMX PC1, PC2, UPC20 and UPC20+.

Senses switch or relay contact closures or provides a logic-level
output. The 3-pin jumpers for each input should be set to SW before
wiring inputs to the Card. An "On" condition is triggered by contact
closures or a logic low of 0 to 1.5 VDC.
An "Off" condition is triggered by a logic high of 2.5 to 5 VDC; set the
associated I/O to switch mode. When used for an output, each I/O
port acts as a switch to ground (GND), and is rated at 200 mA @ 12
VDC.
Senses high- and low-voltage states commonly from AC or DC
signals. This mode provides opto-isolation. The 3-pin jumpers for
each input should be set to VO (voltage mode) before wiring inputs to
the Card.
An "On" condition is triggered by DC levels from 2.5 to 28 VDC (+ or
-), or AC levels from 2.5 to 24 VAC. An "Off" condition is triggered by
DC levels from 0 to 1.5 VDC (+ or -) or AC levels from 0 to 1.5 VAC.

CommandDescription
GDSets the maximum allowable deviation of final servo position when executing the GL command. The
level of the specified input or output will only be reported when a change greater than this deviation
occurs. Deviation 0 is most accurate, but can have some oscillation, so the default is 2, i.e. the position
as read at corresponding input I/O <x+4> can be within +/-2 from the specified position.
Syntax:
Variables:
Example:
Sets I/O 1 servo output to 10.
GLThis command puts the card in servo (positional) control mode. The range of the position is 0-255 (if AD
MODE is set to '8'), or 0-65535 (if AD MODE is set to '10'). See AD MODE earlier in this section for
details.Position 0 is the low end of the potentiometer (lowest voltage); position 255 (or 65535) is the
high end of the potentiometer (highest voltage) with 128 (or 32768) as the middle of the range.
Syntax:
Variables:
Example (Assuming the current position is 0):
Sets Output 1 to "CURRENT OUTPUT 1 SPEED" (positive) and waits until Input 1 reads within
"OUTPUT 1 MAXIMUM DEVIATION" of 255 and then resets the output to zero speed. The speed output
may have a more complex profile than as set by the "GAS" command.
GSSets the speed variable to be used for future positional (GL) commands. The change of speed takes
place immediately even if a positional change operation is currently in progress. The voltage output for
speed 0 (i.e. when no motion is desired) is at the mid-point between the Min and Max output voltages.
The positive speed 127 is the max and negative speed 127 is the min. Other speeds are scaled
proportionately.
Syntax:
Variable:
Example:
Sets Output 1 servo speed to 64 (50%).
