Refer to the NetLinx Master Cards and Modules or NetLinx Hub Cards and Modules instruction manuals for detailed information. 12 card slots for the NetLinx Control Cards that control devices connected to the CardFrame. Provides for installing the CardFrame into an equipment rack. 12 VDC; varies with installed Control Cards. 3.5" x 17.0" x 9.6" (8.89 cm x 43.18 cm x 24.38 cm) 9.1 lbs (4.1 kg) Control Card slots Rack-mounting brackets Rear Panel Components: Card slots Control Card connectors (1-12) +12 VDC PWR Twelve 20-pin black (male) connectors and mating 3.5 mm captive-screw terminals supplied with Control Cards. 20-pin black (male) connectors that connect the Control Cards and external equipment to the CardFrame. 2-pin green (male) connector for connecting a 12 VDC power supply. The 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 if the CardFrame contains eight or more Control Cards, use two 12 VDC power supplies. CardFrame Number DIP switch Front faceplate Enclosure Sets the starting address for the Control Cards in the CardFrame. The 8-position DIP switch address range is 1-3072. Plastic gray faceplate with translucent viewing window. Metal with black matte finish. 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. 2 NXF CardFrame, NetLinx Control Cards, and NetModules NXF CardFrame and NetModules 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. Position Value 1 12 2 24 3 48 4 96 5 192 6 384 7 768 8 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 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 INTEGER Port INTEGER System } // Device number // Port on device // 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: NXF CardFrame, NetLinx Control Cards, and NetModules 3 NXF CardFrame and NetModules NUMBER: PORT: SYSTEM: 16-bit integer represents the device number 16-bit integer represents the port number (in the range 1 through the number of ports on the Controller or device) 16-bit integer represents the system number (0 = this system) 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.

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.
