NI-2100 Specifications (Cont.)
Rear Panel Components (Cont.):
•IR/Serial 
(Ports 5 - 8): 
4 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. 
• 4 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 DIPSwitch:  Sets the communication parameters for the Program port (see Baud Rate 
Settings).
• ID Pushbutton:  Sets the NetLinx ID (Device only) assignment for the device.
• Ethernet Port:  RJ-45 connector provides TCP/IP communication. This is an Auto MDI/MDI-
X enabled port, which allows you to use either straight-through or crossover 
Ethernet cables.
The Ethernet Port LEDs show communication activity, connection status, 
speeds, and mode information:
• SPD (speed) - Yellow LED lights On when the connection speed is 100 
Mbps and turns Off when the speed is 10 Mbps.
• L/A (link/activity) - Green LED lights On when the Ethernet cables are 
connected and terminated correctly, and blinks when receiving Ethernet 
data packets.
• AxLink Port:  4-pin 3.5 mm mini-Phoenix (male) connector that provides data and power to 
external control devices. Green AXlink LED indicates the state of the AXlink 
port.
• Power Port:  2-pin 3.5 mm mini-Phoenix (male) connector.
Included Accessories: • 2-pin 3.5 mm mini-Phoenix (female) PWR connector (41-5025)
