AMX NI-3000 Setting the NetLinx Control Card Addresses NI-4000 Only, DevicePortSystem DPS

Installation and Upgrading

If the cards do not appear in the Workspace window for the selected Master System number: give the system time to detect the inserted cards (and refresh the system) and/or cycle power to the NI-4000 unit.

Setting the NetLinx Control Card Addresses (NI-4000 Only)

The 8-position CardFrame Number DIP switch, located on the rear of the Integrated Controller, 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 1-3064. The factory default CardFrame DIP switch value = 0 (All CardFrame DIP switches in the OFF position). The formula for setting the starting address is:

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

For example:

DIP switch setting, 00010101: (0 + 0 + 0 + 96 + 0 + 384 + 1536) + SLOT #(ex:1) = 2017.

A card in slot number 1 would be device address 2017.

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

Position	1	2	3	4	5	6	7	8
Value	12	24	48	96	192	384	768	1536

ON position

2.Cycle power to the unit for approximately 5 seconds. This allows the unit to 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 1-32,767 for ICSNet (255 for AXlink).

Only the Device value can be set through the DIP switch settings mentioned above.

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 a device is declared in a NetLinx program with just the Device number (System and Port are omitted), the NetLinx Compiler assumes it has a Port number of 1 and a System number of 0. However, you should convert all existing device declarations using the D:P:S (Device:Port:System) notation. This enables certain NetLinx specific debugging features and can help pinpoint other possibly obscure errors.
