ICSLAN LEDs
The ICSLAN LEDs light green when there is an active link on the corresponding ICSLAN port. The light toggles off when a data
packet is sent or received.
There are 4 ICSLAN LEDs on the NX-4200. The NX-2200 and NX-3200 each have one ICSLAN LED (see FIG. 13).

ICSLAN LEDs
SERIAL LEDs
The SERIAL LEDs are two sets of LEDs which light to indicate that the RS-232 ports are transmitting or receiving RS-232, 422, or
485 data (red = TX, yellow = RX). The light toggles on when a data packet is sent or received.
There are two sets of eight SERIAL LEDs on the NX-3200 and NX-4200. The NX-2200 has two sets of four LEDs. The NX-1200 has
two sets of two LEDs (see FIG. 14).

SERIAL LEDs
RELAYS LEDs
The RELAYS LEDs light red to indicate that the corresponding relay port is active. The light toggles off when the relay port is not
engaged.
There are eight RELAY LEDs on the NX-3200 and NX-4200. The NX-2200 has four RELAY LEDs (see FIG. 15).

IR/SERIAL LEDs
The IR/SERIAL LEDs light red to indicate that the corresponding IR/Serial port is transmitting data.
There are eight IR/SERIAL LEDs on the NX-3200 and NX-4200. The NX-2200 has four IR/SERIAL LEDs. The NX-1200 has two IR
LEDs (see FIG. 16).

IR/SERIAL LEDs
I/O LEDs
The I/O LEDs light yellow to indicate that the corresponding I/O port is active.
There are eight I/O LEDs on the NX-3200 and NX-4200. The NX-1200 and NX-2200 has four I/O LEDs (see FIG. 17).
