AMX NetLinx Integrated Controllers NI-3000 - Manual (Page 9)

Introduction
3 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
