NXF CardFrame and NetModules ......................................................................1
NetLinx Control Cards can be installed in the NetLinx® (NXF) CardFrame, the NI-4000, or in modules for
stand-alone operation. The NXF CardFrame accommodates a NetLinx Master (or Hub) card, up to twelve
NetLinx Control cards, and provides a back plane to distribute power and data to/from the cards. The NXF
CardFrame provides terminals on the rear panel for connection to the control cards and a system power supply.
A DIP switch on the rear panel sets the CardFrame's base device number.
The NetLinx Control Cards covered in this document are:
• NXC-COM2Dual COM Port Control Card
• NXC-I/O10Input/Output Control Card
• NXC-IRS44-Port IR/S Control Card
• NXC-REL10Relay Control Card
• NXC-VAI4Analog Voltage Control Card

nal equipment to the CardFrame.
CardFrame 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.
8-position DIP switch address range is 1-3072.
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.
Position12345678
Value122448961923847681536
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 0-32,767. 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 on the Controller or device)
SYSTEM:16-bit integer represents the system number (0 = this system)

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
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.
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.

Sets the SOMEDEVICE port's communication parameters to 115,200 baud, no
parity, 8 data bits, 1 stop bit, and enables RS-485 mode.
TSET BAUD works the same as SET BAUD, except that the changes are not
permanent, and the previous values will be restored if the power is cycled on the
device.
Parity: N (none), O (odd), E (even), M (mark), S (space)
Data: 7 or 8 data bits
Stop: 1 or 2 stop bits
485 Disable: Disables RS-485 mode and enables RS-232/422
485 Enable: Enables RS-485 mode and disables RS-234/422
Note: The only valid 9 bit combination is (baud),N,9,1.
