Installation
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).
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.
Here's the syntax:
NUMBER:PORT:SYSTEM

Baud Rate Settings
Before programming the on-board Master, make sure the baud rate you set matches the communication
parameters set on both your PC’s COM port and those set through your NetLinx Studio v 2.4.
By default, the baud rate is set to 38,400 (bps).
Program Run Disable (PRD) Mode
You can also use the Program port’s Configuration DIP switch to set the on-board Master to Program
Run Disable (PRD) mode according to the settings listed in the table below.
The PRD mode prevents the NetLinx program stored in the on-board Master from running when you
power up the Integrated Controller. This mode should only be used when you suspect the resident
NetLinx program is causing inadvertent communication and/or control problems.
If necessary, place the on-board Master in PRD mode and use the NetLinx Studio v 2.4 program to
resolve the communication and/or control problems with the resident NetLinx program. Then download
the new NetLinx program and try again.

The Integrated Controllers use a 12 VDC-compliant power supply to provide power to the Controller
through the rear 2-pin 3.5 mm mini-Phoenix PWR connector. Use the power requirements information
described in the product’s Specifications table to determine the power draw.
The incoming PWR and GND cable from the power supply must be connected to the corresponding
locations within the PWR connector.
Wiring Length Guidelines
Refer to the following tables for the wiring length information used with your particular NetLinx
Integrated Controller:
Preparing Captive Wires
You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.
1. Strip 0.25 inch (6.35 mm) of 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 wire in the connector. Do not tighten the screws excessively doing
so may strip the threads and damage the connector.

This unit should only have one source of incoming power.
Using more than one source of power to the Controller can result in damage to the
internal components and a possible burn out.
Apply power to the unit only after installation is complete.

Wiring A Power Connection
To use the 2-pin 3.5 mm mini-Phoenix connector with a 12 VDC-compliant power supply, the incoming
PWR and GND cables from the external source must be connected to their corresponding locations on
connector (FIG. 3).
1. Insert the PWR and GND wires on the terminal end of the 2-pin 3.5 mm mini-Phoenix cable. Match
the wiring locations of the +/- on both the power supply and the terminal connector.
2. Tighten the clamp to secure the two wires. Do not tighten the screws excessively; doing so may strip
the threads and damage the connector.
3. Verify the connection of the 2-pin 3.5 mm mini-Phoenix to the external 12 VDC-compliant power
supply.

Using the 4-pin Mini-Phoenix Connector For Data With External Power
To use the 4-pin 3.5 mm mini-Phoenix (female) captive-wire connector for data communication and
power transfer, the incoming PWR and GND cable from the 12 VDC-compliant power supply must be
connected to the AXlink cable connector going to the Integrated Controller. FIG. 5 shows the wiring
diagram. Always use a local power supply to power the Integrated Controller unit.
Make sure to connect only the GND wire on the AXlink/PWR connector when using a separate 12 VDC
power supply. Do not connect the PWR wire to the AXlink connector’s PWR (+) opening.
ICSNet Port: Connections and Wiring
Each port provides up to 500 mA of current. The following tables show the signal and pinouts/pairing

When you connect an external power supply, do not connect the wire from the PWR
terminal (coming from the external device) to the PWR terminal on the Phoenix
connector attached to the Controller unit. Make sure to connect only the AXM, AXP,
and GND wires to the Controller’s Phoenix connector when using an external power
supply.

ICSHub Port: Connections and Wiring
The two ICSHub RJ-45 connectors on the rear of the Master card provide data to other Hubs connected
to a downstream system. Hubs allow you to connect multiple NetLinx Hubs together in a daisy-chain
configuration. Connect the OUT port to the IN port on the second or downstream NetLinx Hub.
 Use CAT5 cables for all ICSHub connections.
 Do not connect the last hub in a daisy-chain configuration into the first Hub.

Unlike the ICSNet ports, the ICSHub connections require a specific polarity. The
IN/OUT configuration, on the Hub ports, was implemented to use the same cables as
ICSNet, but these ports need TX and RX crossed. You must connect an OUT to an
IN, or an IN to an OUT port.
This is done simply to keep the polarity straight. The Hub bus is still a bus. All Hub
connections are bi-directional.
