Quick Start Guide
NI-2100 NetLinx Integrated Controller
For more detailed installation, configuration, programming, file transfer, and 
operating instructions, refer to the NetLinx Integrated Controllers (NI-2100, 
NI-3100, and NI-4100 Series) Instruction Manual, available online at 
www.amx.com. 
Overview
The NI-2100 unit (FG2105-04) is geared to meet the specific control and 
automation needs of a single room environment, these needs may include 
the integration of a limited number of video players, projectors, lighting, 
thermostats, and other electronic equipment. The NI-2100 provides support 
for 3 RS-232/RS-422/RS-485 Ports, 4 IR/Serial Output ports, 
4 Digital Input/Output ports, and 4 Relays. The NI-2100 can be upgraded to 
provide 1 ICSHub and 2 ICSNet ports by either installing the optional 
ICSNet daughter card (FG2105-10) or purchasing this upgrade as an 
included feature of the NI-2100 Kit (FG2105-14).
ATTENTION!
Verify you are using the latest NI firmware for the on-board Master. Verify 
you are using the latest version of NetLinx Studio (available for download 
from www.amx.com).

Front Panel 
 Components:
• LINK/ACT: Green LED blinks when the Ethernet cables are 
connected and terminated correctly. 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 and 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: 3 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
• 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. 
• 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: Provides an installation option for the 
Integrated Controller to be mounted into an equipment rack, 
when used with the Installation Kit (KA2105-01).
NI-2100 Specifications (Cont.)
Rear Panel 
 Connectors:
• 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.
• ICSNet: Two RJ-45 connectors for ICSNet interface 
  (provided by ICSNet daughter card).
• ICSHub Out: RJ-45 connector provides data to a Hub connected 
to the Controller (provided by ICSNet daughter card).
•Relay (Port 4): 4-channel single-pole single throw relay ports with 
each relay being independently controlled and supporting up to 
4 independent external relay devices.
• Digital I/O (Port 9): 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 5 - 8): Four 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. Four 
IR/Serial data signals can be generated simultaneously. IR ports 
support data mode (at limited baud rates and wiring distances).
• Program Port: RS-232 DB9 connector (male) can be connected to 
a DB9 port on a PC. This connector can be used with serial and 
NetLinx programming commands, as well as other DB9 capable 
devices, to both upload/download information from the NetLinx 
Studio program.
• Configuration DIP Switch: Sets the communication parameters for 
the Program port.
• ID Pushbutton: Sets the NetLinx ID (Device only) assignment for 
the device.
