Introduction

NetLinx Integrated Controllers

NI-2000 Specifications (Cont.)

Front Panel Components:

LINK/ACT • Green LED lights when the Ethernet cable is connected and an active link

is established. This LED also blinks when receiving Ethernet data packets.

Status • Green LED lights to indicate that the system is programmed and

communicating properly.

Output • Red LED lights when the Controller transmits data, sets channels On/Off,

sends data strings, etc.

Input • Yellow LED blinks when the Controller receives data from button pushes,

strings, commands, channel levels, etc.

RS-232/422/485 LEDs • Three sets of red and yellow LEDs light to indicate the rear DB9 Ports 1-3

are transmitting or receiving RS-232, 422, or 485 data:

- TX LEDs (red) light when transmitting data

- RX LEDs (yellow) light when receiving data

- LED activity reflects transmission and reception activity

Relay LEDs • Four red LEDs light to indicate the rear relay channels 1-4 are active

(closed).

• These LEDs reflect the state of the relay on Port 4

• If the relay is engaged = LED On and if the relay is Off = LED Off

IR/Serial LEDs • Four red LEDs light to indicate the rear IR/Serial channels 1-4 are

transmitting control data on Ports 5-8

• LED indictor for each IR port remains lit for the length of time that IR/Serial

data is being generated

I/O LEDs • Four yellow LEDs light when the rear I/O channels 1-4 are active

• LED indicator for each I/O port reflects the state of that particular port

Rack-mount brackets • Provide an installation option for the Integrated Controller to be mounted

into an equipment rack.

Rear Panel Components:

RS-232/422/485 (Ports 1 -3) • Three RS-232/422/485 control ports using DB9 (male) connectors with

XON/XOFF (transmit On/transmit Off), CTS/RTS (clear to send/ready to

send), and 300-115,200 baud.

• Channel range = 1-255

• Channels 1-254 provide feedback

• Channel 255 (CTS Push channel): Reflects the state of the CTS Input if a

'CTSPSH' command was sent to the port

• Output data format for each port is selected via software

• Three DB9 connectors provide RS-232/422/485 termination

ICSNet • Two RJ-45 connectors for ICSNet interface

ICSHub Out • Single RJ-45 connector provides data to another Hub connected to the

Controller

Relay (Port 4) • Four-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 VDC or 28 VAC @ 1 A

• One 8-pin 3.5 mm mini-Phoenix (female) connector provides relay

termination
