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.

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.

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

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.

Using the RESET Button
Pressing the RESET button resets the processor in the same manner as cycling power. You can
also use the RESET button to troubleshoot network connectivity.
The RESET button is located on the bottom of the controller.
1. Hold the RESET button for 5 seconds, and then release it to boot the IC-3173 into safe
mode and enable Console Out.
2. After booting the controller into safe mode, hold the RESET button again for 5 seconds to
enable IP reset, which resets the network adapter to its default configuration.
Safe Mode
When you boot the IC-3173 into safe mode, it launches only the services necessary for
updating its configuration and installing software. To resume normal operations, press the
RESET button for less than 5 seconds.
IP Reset
Use IP reset to reset the TCP/IP settings when moving the system from one subnet to another
or when the current TCP/IP settings are invalid.
When the IC-3173 is in the IP reset state, the IP address of the network port resets to DHCP or
a link-local address. You can then set up a new network configuration for the IC-3173 from a
development machine on the same subnet, or you can connect the IC-3173 directly to the
development computer.
Note By default, the target automatically attempts to connect to the network using
DHCP. If the target is unable to initiate a DHCP connection, the target connects to
the network with a link-local IP address (169.254.x.x).
Replacing the Battery
The IC-3173 contains a user-replaceable battery. The battery compartment is located on the
left side of the device as you look at the device from the front. Take the following steps to
replace the battery:
Caution Before removing the battery cover, disconnect all power connectors and
I/O cables from the device. To prevent damage from electrostatic discharge (ESD),
ground the unit and yourself by using a grounding strap or touching a grounded
object, such as a computer chassis.
18 | ni.com | IC-3173 User Manual

1. Use a Phillips head screwdriver to remove the two screws holding the battery cover plate.
Remove the plate, then remove battery from the device.
2. Insert a new battery in the device. Ensure the positive terminal of the battery faces
outward. Refer to the device specifications for the required battery type.
3. Replace the battery cover plate.
Replacing the battery resets the BIOS settings to their default values.
Increasing the Battery Life
When storing the controller, you can disconnect the battery to deactivate the real-time clock
and make the BIOS configurations non-volatile. Take the following steps to disconnect the
battery:
Caution Before removing the battery cover, disconnect all power connectors and
I/O cables from the device. To prevent damage from electrostatic discharge (ESD),
ground the unit and yourself by using a grounding strap or touching a grounded
object, such as a computer chassis.
1. Use a Phillips head screwdriver to remove the two screws holding the battery cover plate.
Remove the plate.
2. Locate the BATTERY CONNECT switch above the battery and move the switch toward
the front panel of the device. The battery is now disconnected from the device.
3. Replace the battery cover plate.
Mounting the IC-3173
This section provides information for creating a custom mount for the IC-3173. If you do not
want to create a custom mount, a panel mount kit for the IC-3173 is available from National
Instruments (part number 784791-01).
Caution Do not position the IC-3173 with the heat sinks resting on any surface.
Doing so may cause the IC-3173 device to overheat. Refer to the IC-3173
Specifications for temperature specifications.
To obtain the maximum allowable ambient temperature, you must mount the IC-3173
vertically. The following figures provide dimensional drawings and clearance information for
the IC-3173.
