NXF CardFrame, NetLinx Control Cards, 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.
2. Cycle power for approximately 5 seconds, so the system can read the new device number
settings.
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:
Position 12345678
Value 12 24 48 96 192 384 768 1536
Factory default DIP switch value = 0 (zero) (All DIP switches are in the OFF position).
