Using the ICSLAN Network
The default IP address for the ICSLAN network is 198.18.0.1 with a subnet mask of 255.255.0.0.
It is important that the ICSLAN and LAN subnets do not overlap. If the LAN port is configured such that its address
space overlaps with the ICSLAN network, the ICSLAN network will be DISABLED.
DHCP Server
The ICSLAN port has a built-in DHCP server. This DHCP server is enabled by default and will serve IP addresses to any
connected devices set to DHCP mode.
The DHCP server can be disabled from telnet with the command:
SET ICSLAN
The DHCP address range is fixed. The server will provide addresses in the range x.x.0.2 through x.x.63.255.
Devices using static IP addresses on the ICSLAN network should be set within the reserved static IP address range of
x.x.64.1 to x.x.255.254.
Opening LAN and ICSLAN Sockets from Code
When opening sockets from NetLinx or Java code there is no mechanism to indicate which network to use. The
controller will open the socket on whichever network has an IP subnet that matches the address provided in the command
to open the socket. There is no indication which network was used, only whether the socket was created successfully.
USB Port
The front panel of all NX-series controllers features one Type-A USB port you can use to connect a mass storage device
for loading .jar files and IR data files (.irl), reading or writing configuration files and log files, or updating the firmware
on the unit. The rear panels of the NX-2200/3200/4200 also feature an additional USB port.
Note: This USB port only supports a FAT32 file system.
This USB port (FIG. 33) uses standard USB cabling to connect to any mass storage or peripheral devices.

Note: USB hubs are not supported on this port.
ID Pushbutton
All NX-series controllers feature an ID pushbutton which you can use to toggle between static and dynamic IP
addressing. You can also use the pushbutton to reset the default settings on the controller or restore the controller to its
factory firmware image.
FIG. 34 displays the ID pushbutton for the NX-series controllers.

Note: The ID pushbutton is located on the front panel of the NX-1200 and not on the rear panel.
Switching to Static or Dynamic IP Addressing.
To toggle between static or dynamic IP addressing, the controller cannot be currently booting or it must be in ID Mode.
If these conditions are met, holding the ID pushbutton for 10 seconds changes the current IP addressing mode.
Restoring the Controller Settings to the Factory Defaults
To restore the controller settings to the factory defaults, the controller must be currently booting and you must press the
ID pushbutton for 10 seconds. The controller is booting when the System and Input LEDs are both ON and the Output
LED is OFF. This includes resetting the static IP address to its default and deleting the NetLinx program.
WARNING! Pressing the ID pushbutton for 20 seconds restores the factory firmware image on the controller. Do not
press the pushbutton significantly longer than the necessary 10 seconds if you only want to restore the default settings on
the controller.
Restoring the Controller's Factory Firmware Image
To restore the controller's factory firmware image, the controller must currently be booting and you must press the ID
pushbutton for 20 seconds. This also deletes all code and IRL files.
