NI-3101-SIG Signature Series NetLinx Integrated Controller
NI-3101-SIG Specifications (Cont.)
Front Panel Components:
Input/Output LEDs • White Output LED blinks when the Controller transmits data, sets channels
On/Off, sends data strings, etc. White Input LED blinks when it receives
data from button pushes, strings, commands, channel levels, etc.
RS-232/422/485 LEDs • Six sets of blue and white LEDs light to indicate the rear serial Ports 1 - 6
are transmitting or receiving RS-232, 422, or 485 data:
- TX LEDs (blue) light when transmitting data
- RX LEDs (white) light when receiving data
- LED activity reflects transmission and reception activity
Relay LEDs • Eight blue 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 blue 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 white 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
Rear Panel Connectors:
RS-232/422/485 (Ports 1 - 6)•Six 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
• Six DB9 connectors provide RS-232/422/485 termination
Relay (Port 8) • Eight-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 VDC or 28 VAC @ 1 A
• Two 8-pin 3.5 mm mini-Phoenix (female) connectors provide relay
termination
