Introduction

NI-2000, NI-3000, NI-4000 Hardware Reference Guide
NI-4000 Specifications (Cont.)
Rear Panel Connectors:
RS-232/422/485 (Ports 1 -7)
•
Seven
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
• Seven DB9 connectors provide RS-232/422/485 termination
ICSNet
•
Two
RJ-45 connectors for ICSNet interface
ICSHub Out
• RJ-45 connector provides data to another Hub connected to the Controller
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
Digital I/O (Port 17)
• Eight-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 = 1-8
• 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
• 10-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 9-16)
•
Eight
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
• Eight 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).
• Two 8-pin 3.5 mm mini-Phoenix (female) connectors provide IR/Serial port
termination
