NetLinx Integrated Controllers
NI-4100 Specifications (Cont.)
Front Panel Components:
LINK/ACT • Green LED blinks when the Ethernet cable is connected and an active link
is established. This LED also blinks when receiving Ethernet data packets.
Status • Green LED blinks to indicate that the system is programmed and
communicating properly.
Output • Red LED blinks 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 • Seven sets of red and yellow LEDs light to indicate the rear DB9 Ports 1-7
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 • Eight red LEDs light to indicate the rear relay channels 1-8 are active
(closed)
• These LEDs reflect the state of the relay on Port 8
• If the relay is engaged = LED On and if the relay is Off = LED Off
IR/Serial LEDs • Eight red LEDs light to indicate the rear IR/Serial channels 1-8 are
transmitting control data on Ports 9-16
• LED indictor for each IR port remains lit for the length of time that IR/Serial
data is being generated
I/O LEDs • Eight yellow LEDs light when the rear I/O channels 1-8 are active
• LED indicator for each I/O port reflects the state of that particular port
