Hardware Reference Guide - NX-Series NetLinx Integrated Controllers
Configuration DIP Switch
The NX-series controllers each have a configuration DIP switch which allows for certain operations to occur during
boot-time. The DIP switch positions are assigned as follows:
Switch for Program Run Disable
Switch for Boot from External SD Card (only applicable to the NX-3200 and NX-4200.)
Note:
The Configuration DIP Switch is located on the front panel of the NX-1200 and not the rear panel.
FIG. 30 displays the Configuration DIP Switch for the NX-series controllers.

Program Run Disable (PRD) Mode
You can use the Configuration DIP switch to set the on-board Master to Program Run Disable (PRD) mode. PRD mode
prevents the NetLinx program stored in the on-board Master from running when you power up the Integrated Controller.
You should only use PRD mode 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 program to resolve the communication
and/or control problems with the resident NetLinx program. Then download the new NetLinx program and try again.
FIG. 31 displays the default DIP switch settings and the settings for PRD mode. To switch to PRD mode, move the
position 1 DIP switch to ON.

DIP Switch settings - PRD mode
Note:
Consider equating PRD Mode to a PC’s SAFE Mode setting. With PRD mode, you can continue to power a unit,
update the firmware, and download a new program while circumventing any problems with a currently downloaded
program. You must power cycle the unit after activating/deactivating PRD mode on Program Port DIP switch #1.
ICSLAN Ports
The NX-2200/3200/4200 controllers have two types of Ethernet ports: LAN and ICSLAN. The LAN port is used to
connect the master to an external network, and the ICSLAN ports are used to connect to other AMX equipment or
third-party A/V equipment. The ICSLAN ports on all models provide Ethernet Communication to connected AMX
Ethernet Equipment in a way that is isolated from the primary LAN connection.
The ICSLAN port is a 10/100 Port RJ-45 connector and Auto MDI/MDI-X enabled. The NX-4200 features four
ICSLAN ports, while the NX-2200/3200 feature one each. The ports on the NX-4200 feature Power-over-Ethernet
(PoE). The ports support IPv4 and IPv6 networks, as well as HTTP, HTTPS, Telnet, and FTP.

ICSLAN ports
When powered by an AC source, the NX-4200 can supply power via PoE to each port on the 4-port switch. The
NX-4200 supports hi-powered PoE (802.3at STANDARD), but the total power draw of all four ports cannot exceed
72W.
The ICSLAN port gets its IP addresses in one or more of the following ways:
IPv4 - Static assignment of the subnetwork address by the user
IPv6 - Link local address
