About the IC-3173

The IC-3173 is a high-performance, small, fanless embedded computer designed for rugged

industrial applications. The IC-3173 also provides multiple digital input/output (I/O) options

for communicating with external devices.

Hardware Overview

The IC-3173 front panel consists of four Gigabit Ethernet ports with Power over Ethernet

(PoE), one RS-232/RS-485 serial port, one standard Gigabit Ethernet Port, two USB 3.0 ports,

four USB 2.0 ports, and two DisplayPort connectors.

The IC-3173 front panel also includes LEDs for communicating system status and a 44-pin

Digital I/O port. The Digital I/O port offers 8 isolated inputs, 8 isolated outputs, 2 bidirectional

differential I/O (RS-422) or single-ended input lines that can be used with a quadrature

encoder, and 8 bidirectional TTL lines.

Connector Pinouts

The IC-3173 provides the following connectors.

DisplayPort

Use the DisplayPort connectors to connect one or more monitors to implement a local HMI for

your controller. You can develop a single real-time VI to use for both your user interface and

system logic. For more information, refer to the Using the Embedded UI to Access RT Target

VIs topic in the LabVIEW Help. For up-to-date information about supported NI cables and

accessories, refer to the pricing section of the product page at ni.com.

Use an appropriate adapter cable to connect a DisplayPort connector to a VGA or DVI

connector. The following figure lists the DisplayPort pins and signals.

Ethernet Ports

The IC-3173 provides one standard Gigabit Ethernet network port and four Gigabit Ethernet

ports with Power over Ethernet (PoE). The Ethernet ports provide a connection between the

IC-3173, a network, and other Ethernet devices. The IC-3173 automatically detects the speed

of the connection and configures itself accordingly.

If a PoE-capable device is plugged into an Ethernet port with PoE, the IC-3173 automatically

supplies power to the device. When the IC-3173 supplies PoE, the LED that corresponds to the

port illuminates. When you unplug a PoE device, PoE is automatically disabled. You can use

non-PoE Ethernet devices with the PoE-enabled Gigabit Ethernet ports.

A CAT 5e or CAT 6 1000Base-T Ethernet cable is required to achieve 1,000 Mbps (Gigabit)

Ethernet performance. CAT 5 Ethernet cables are not guaranteed to meet the necessary

requirements. While CAT 5 cables may appear to work at 1,000 Mbps, CAT 5 cables can cause

bit errors, resulting in degraded or unreliable network performance.

Digital I/O

The 44-pin Digital I/O port on the IC-3173 offers 8 isolated inputs, 8 isolated outputs, 2

bidirectional differential inputs (RS-422) or single-ended input lines that can be used with a

quadrature encoder, and 8 bidirectional TTL lines. The Digital I/O port can be connected to

any appropriate shielded device or connector block using a shielded cable.

NI recommends the following digital I/O cables for the IC-3173.

Cable Part Number

44-pin D-sub male to pigtail cable 156083-03 for 3 meter cable

44-pin D-sub male to 44-position D-sub female cable 156084-03 for 3 meter cable

Wiring an Isolated Input

You can wire an isolated input to a sourcing output device.

8| ni.com | IC-3173 User Manual

Caution Do not apply a voltage greater than 30 VDC to the isolated inputs.

Voltage greater than 30 VDC may damage the IC-3173.

Wiring an Isolated Output

The digital isolated output circuits source current to external loads.

When an inductive load, such as a relay or solenoid, is connected to an output, a large counter-

electromotive force may occur at switching time due to energy stored in the inductive load.

This flyback voltage can damage the outputs and the power supply.

To limit flyback voltages at the inductive load, install a flyback diode across the load. Mount

the flyback diode as close to the load as possible. Use this protection method if you connect

any of the isolated outputs on the IC-3173 to an inductive load.

The following image shows an example of an isolated output wired to an external load with a

flyback diode installed across the load.

IC-3173 User Manual | © National Instruments | 9

Caution Do not draw more than 35 mA from each isolated output when VISO is

5 V. Do not draw more than 80 mA from each isolated output when VISO is 24 V.

Connecting to Differential I/O

The IC-3173 accepts differential (RS-422) line driver inputs. Each of the two differential I/O

can be configured as an output. Use shielded cables for all applications. Unshielded cables are

more susceptible to noise and can corrupt signals.
