Hardware Reference Guide - NX-Series NetLinx Integrated Controllers
NX-4200 Specifications (Cont.)
Program Port
1 Type-B USB port that can connect to a USB port on a PC and access the NetLinx
Studio program for controller configuration.
USB Port
1 Type-A USB port for connecting a mass storage device for loading .tkn files,
reading or writing configuration files and log files, or updating the firmware on the
unit.
Display Control Button
1 rocker-style tactile button for stepping through the supported status parameters
displayed on the front panel LCD.
LCD Display
A 2 line by 20 character alphanumeric display for viewing status parameters.
Master LEDs:
• LINK/ACT (green): Blinks when the Ethernet cables are connected and terminated
correctly. Also blinks when receiving Ethernet data packets.
• STATUS (green): Blinks to indicate that the system is programmed and
communicating properly.
• OUTPUT (red): Blinks when the Controller transmits data, sets channels On and
Off, sends data strings, etc.
• INPUT (yellow): Blinks when the Controller receives data from button pushes,
strings, commands, channel levels, etc.
ICSLAN LEDs
4 LEDs which blinks when the RJ-45 cables to ports 1-4 are connected and
terminated correctly. The LEDs also blink when receiving LAN data packets.
Serial LEDs (red):
2 sets of eight LEDs, each of which light to indicate that the corresponding RS-232
ports (2-4, 6-8) and RS-232/422/485 ports (1, 5) are transmitting or receiving
RS-232, 422, or 485 data.
Relay LEDs (red):
1 set of 8 LEDs, each of which light to indicate the corresponding relay channels
(1-8) are active (closed). These LEDs reflect the state of the relay on port 21.
IR/Serial LEDs (red):
1 set of 8 LEDs, each of which light to indicate the IR/Serial channels 1-8 are
transmitting control data on the corresponding IR/Serial ports (ports 11-18). The
LED indicator for each IR port remains lit for the length of time that IR/Serial data is
being generated.
Digital I/O LEDs
(yellow):
1 set of 8 LEDs, each of which light when the corresponding rear I/O channels (1-8)
are active. The LED for each I/O port reflects the state of that particular port.
Rear Panel Components
RS-232 (Ports 2-4, 6-8)
6 5-pin RS-232 control ports using 5-pin 3.5 mm mini-Phoenix (male) connectors
with XON/XOFF (transmit on/transmit off), CTS/RTS (clear to send/ready to send).
Supports 150-115,200 baud.
RS-232/422/485
(Ports 1, 5):
2 10-pin RS-232/422/485 control ports using 10-pin 3.5 mm mini-Phoenix (male)
connectors with XON/XOFF (transmit on/transmit off), CTS/RTS (clear to send/
ready to send). Supports 150-115,200 baud.
Relays (Port 21):
8-channel single-pole single throw relay ports
Each relay is independently controlled.
Supports up to 8 independent external relay devices
Channel range = 1-8
Each relay can switch up to 24 V
DC
or 28 V
AC
@ 1 A
Two 8-pin 3.5 mm mini-Phoenix (male) connectors provide connection to relays
Digital I/O (Port 22):
8-channel binary I/O port for contact closure with each input being capable of
voltage sensing. Input format is software selectable with interactive power sensing
for IR ports.
IR/Serial (Ports 11-18):
8 IR/Serial control ports support high-frequency carriers of up to 1.142 MHz with
each output being capable of two electrical formats: IR or Serial.
8 IR/Serial data signals can be generated simultaneously.
IR ports support data mode (at limited baud rates and wiring distances).
AxLink Port:
2 4-pin 3.5 mm mini-Phoenix (male) connector that provides data and power to
AxLink external control devices. Green AxLink LED indicates the state of the AxLink
port.
SDHC Slot:
1 SDHC card slot for future use.
Configuration DIP
Switch:
The Configuration DIP Switch allows you to set boot-time operations (see the
section on page 30 for more information.)
