Hardware Reference Guide - NX-Series NetLinx Integrated Controllers
NX-2200 Specifications (Cont.)
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.
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 (red):
1 LED which blinks when the RJ-45 cables to port 1 is connected and terminated
correctly. The LED also blinks when receiving LAN data packets.
Serial LEDs (red):
2 sets of four LEDs, each of which light to indicate that the corresponding RS-232 ports
(2-4) and RS-232/422/485 port (1) are transmitting or receiving RS-232, 422, or 485
data.
Relay (red):
4 LEDs light to indicate the relay channels 1-4 are active (closed). These LEDs reflect
the state of the relay on port 21.
IR/Serial (red):
4 LEDs light to indicate the IR/Serial ports 11-14 are transmitting control data. LED
indicator for each IR port remains lit for the length of time that IR/Serial data is being
generated.
Digital I/O (yellow):
Lights when the I/O channels 1-4 are active. The LED for each I/O port reflects the state
of that particular port.
Rear Panel Components:
RS-232/422/485
(Port 1):
1 10-pin RS-232/422/485 control ports using a 10-pin 3.5 mm mini-Phoenix (male)
connector with XON/XOFF (transmit on/transmit off), CTS/RTS (clear to send/ready to
send). Supports 300-115,200 baud.
RS-232 (Ports 2-4):
3 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
300-115,200 baud.
Relay (Port 21):
4 2-pin 4-channel single-pole single-throw relay ports.
Each relay is independently controlled.
Supports up to 4 independent external relay devices
Channel range = 1-4
Each relay can switch up to 24 V
DC
or 28 V
AC
@ 1 A
8-pin 3.5 mm mini-Phoenix (male) connector provides connection to relays
Digital I/O (Port 22):
4-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 11-14):
4 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.
4 IR/Serial data signals can be generated simultaneously.
IR ports support data mode (at limited baud rates and wiring distances).
AxLink Port:
4-pin 3.5 mm mini-Phoenix (male) connector that provides data and power to external
AxLink control devices. Green AxLink LED indicates the state of the AxLink port.
Configuration DIP
Switch:
The Configuration DIP Switch allows you to set boot-time operations (see
section on page 30 for more information.)
ICSLAN:
1 RJ-45 connector for ICSLAN interface.
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.
ID Pushbutton:
1 black ID pushbutton used during boot to revert to factory configuration or factory
firmware. Also used after boot to toggle IP mode between Static and DHCP.
