Introduction

NI-2000 Specifications (Cont.)

Rear Panel Connectors (Cont.):

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
	• 8-pin 3.5 mm mini-Phoenix (female) connector provides relay termination
Digital I/O (Port 9)	• Four-channel binary I/O port for contact closure
	• Each input is capable of voltage sensing. Input format is software
	selectable.
	• Interactive power sensing for IR ports
	• Channel range = 1-4
	• All inputs are assigned to respective IR/Serial ports for "automatic" power
	control through the use of software commands. Power control is provided
	via commands such as: ’PON’, ’POF’, ’POD’, ’DELAY’, I/O Link etc.).
	• Contact closure between GND and an I/O port is detected as a PUSH
	• When used as voltage input - I/O port detects a low signal (0- 1.5 VDC) as
	a PUSH and a high signal (3.5 - 5 VDC) as a RELEASE
	• When used as an output - each I/O port acts as a switch to GND and is
	rated at 200 mA @ 12 VDC
	• 6-pin 3.5 mm mini-Phoenix (female) connector provides I/O port
	termination
	Note: This IO port uses 5V logic but can handle up to 12V without harm. It
	can handle up to 12V on the input. At higher voltages you run a higher risk of
	surge damage.
IR/Serial (Ports 5-8)	• Four IR/Serial control ports support high-frequency carriers of up to
	1.142 MHz.
	• Each output is capable of three electrical formats: IR, Serial, and Data
	• Four IR/Serial data signals can be generated simultaneously.
	• Channel range = 1-32,767
	• Channels 1-128 (output): IR commands
	• Channels 129-253: used as reference channels
	• Channel 254 (feedback): Power Fail (used with 'PON' and 'POF'
	commands)
	• Channel 255 (feedback): Power status (when IO Link is set)
	• IR ports support data mode (at limited baud rates and wiring distances).
	• 8-pin 3.5 mm mini-Phoenix (female) connector provides IR/Serial port
	termination
Program port	• RS-232 DB9 connector (male) can be connected to a DB9 port on a
	computer; used with serial commands, NetLinx programming commands,
	other DB9 capable devices, and to upload/download information from the
	NetLinx Studio 2.4 program.
Configuration DIP switch	• Sets the communication parameters for the Program port.
ID pushbutton	• Provides the NetLinx ID (Device only) assignment for the device.
	• The D notation is used to represent a device number.
	• Refer to the NetLinx Integrated Controller WebConsole & Programming
	Guide for details.
Ethernet port	• RJ-45 port for 10/100 Mbps communication. This port automatically
	negotiates the connection speed (10 Mbps or 100 Mbps) and whether to
	use half duplex or full duplex mode.
