GoMax NXSmart Vision Accelerator:User Manual 4
Introduction
GoMax NXis onlycompatible with Gocatorfirmware 6.1 SR1 (firmware version 6.1.29.3) and
later or GoPxL 1.0 and later. Loading an earlier firmware version will make the device
unusable.
Notational Conventions
This documentation uses the following notational conventions:
Follow these safety guidelines to avoid potential injury or property damage.
Consider this information in order to make best use of the product.
The GoMax NXSmart Vision Accelerator is a hardware solution that accelerates any Gocator sensor
to meet inline production speeds, without the need for a PC. The plug and play functionality of
GoMax NXlets you quickly and easily add powerful data processing to a Gocator system, achieving
faster cycle times and enhancing overall inspection performance.
GoMax NXprovides this compute power thanks to its 384-core GPU and 48 Tensor cores—all in a
compact, rugged case.
To accelerate sensors, GoMax NX takes over a portion of the sensor’s data processing (data
generation, 3D measurement, and control).
Relationship between GoMax NX(right)and a sensor (left)
GoMax NXis ideal for accelerating a single Gocator snapshot sensors (such as Gocator 3506) or
multi-sensor Gocator laser or confocal line profile sensor systems.

The Ethernet-based output protocols (Gocator, EtherNet/IP, ASCII, Modbus, and PROFINET) are also
identical to those found on an unaccelerated sensor, and are fully supported.
The web interface on an accelerated sensor is identical to the interface on an unaccelerated sensor.
For this reason, after you have configured GoMax NX, you should refer to the GoPxLuser manuals,
available on LMI's website.

Safety and Maintenance
The following sections describe the safe use and maintenance of GoMax NX vision accelerators.
GoMax NXis onlycompatible with Gocatorfirmware 6.1 SR1 (firmware version 6.1.29.3) and
later or GoPxL 1.0 and later. Loading an earlier firmware version will make the device
unusable.
Electrical Safety
Failure to follow the guidelines described in this section may result in electrical shock or
equipment damage.
Sensor systems that GoMax NX is connected to should be connected to earth ground
All sensors in the system should be connected to earth ground through their housing. All sensors
should be mounted on an earth grounded frame using electrically conductive hardware to ensure
the housing of the sensor is connected to earth ground. Use a multi-meter to check the continuity
between the sensor connector and earth ground to ensure a proper connection.
Minimize voltage potential between system ground and sensor ground
Care should be taken to minimize the voltage potential between system ground (ground reference
for I/O signals) and sensor ground. This voltage potential can be determined by measuring the
voltage between Analog_out- and system ground. The maximum permissible voltage potential is 12 V
but should be kept below 10 V to avoid damage to the serial and encoder connections.
Use the power supply provided with the unit
If the power supply or cords get damaged, contact LMI Technologies for a replacement.
Use care when handling powered devices
Wires connecting to the GoMax NX unit should not be handled while the unit is powered. Doing so
may cause electrical shock to the user or damage to the equipment.
Cleaning and Maintenance
Keep heatsink fins clear and clean
To avoid overheating of the GoMax NX unit, make sure the unit's heatsink fins are clean and clear.
Environment
Avoid installing the GoMax NX unit in hazardous environments
To ensure reliable operation and to prevent damage to the GoMax NX unit, avoid installing the unit
in locations

Adding GoMax NX to a Sensor System
LMIrecommends adding GoMax NX to a sensor system that is already fully set up and configured.
For information on setting up a sensor system, see the user manual of the sensors used in the
system.
Follow the instructions in the following sections to install and perform the initial configuration of a
GoMax NX unit.
Sensors you intend to accelerate using GoMax NX must be running GoPxL1.0 or higher.

Connecting Power
Power is provided by the included power supply. The plug type depends on the region in which you
are using the unit.
Use only the provided power supply with the GoMax NX unit. Using a higher voltage power
supply will damage the unit.
LMIrecommends powering up the GoMax NXunit and performing the initial configuration of the
unit before physically connecting it to the sensor system.
To connect power:
1. Connect the power supply connector to the unit.
2. Plug the power adapter into an available electrical outlet.
3. Press the power button.

An LED indicator on the unit lights when power is applied.
The unit is ready for initial configuration (setting an IPaddress).

GoMax NX Smart Vision Accelerator:User Manual Adding GoMax NX to a Sensor System • 15
Setting the IP Address
Each GoMax NX unit and Gocator sensor on the sensor system network must have a unique IP
address. By default, the IPaddresses of the GoMax NX unit's ETH1 Ethernet port is set to
192.168.1.6. By default, the ETH2 port is set to 192.168.2.6.
If these addresses conflict with sensors in your sensor system, or if your system will contain multiple
GoMax NX units, you will have to set the IPaddresses of each GoMax NX unit to avoid conflicts.
To set the IP address of a GoMax NX unit:
1. Using an Ethernet cable, first connect a computer directly to the ETH1 port on the GoMax NX unit.
2. On the computer, launch an Internet browser and navigate to 192.168.1.6.
The GoMax NXweb interface is displayed.

GoMax NX Smart Vision Accelerator:User Manual Adding GoMax NX to a Sensor System • 16
If you can't connect to the GoMax NX unit, or if you don't know what the unit's IPaddress is, follow the
instructions in Discovering a GoMax NX IPAddress on page18.
3. If you haven't already done so, in the lower left of the interface, click the open icon to pin the navigation bar
on the left.
It's not necessary to do this, but for first-time users, it can help understand the user interface more quickly.
4. If the Settings page isn't already displayed, click Settings in the navigation bar.
The Settings page is displayed (see above).
5. Under Network Settings, under Interface 1 or Interface 2, set the IP address and click Save Changes.

The GoMax NXunit restarts after you confirm you want to continue with the changes. Changing network
settings stops the acceleration of any accelerated sensors.
After the GoMax NXunit restarts, its IP address is changed.
6. Disconnect the laptop from the GoMax NXunit.

Discovering a GoMax NX IPAddress
If you can't find or connect to a GoMax NX unit, use the GoPxLDiscovery tool to find it on your
network.You identify a GoMax NXunit by looking for "gomax" in the Application IDcolumn. The tool
also lets you launch the GoMax NXinterface in your browser.

Mounting
You can mount GoMax NX units to a DINrail or directly to a wall or frame using the provided
mounting hardware.
For details on GoMax's dimensions and mounting holes, see GoMax NX on page35.
Using DIN Rail Clips
LMI provides a DIN rail clip plate, a DIN rail clip, and M3 screws to mount GoMax NX on a DIN rail.
The plate allows multiple orientations of the unit using different sets of standoffs. Attach the DIN rail
clip plate to the back of the unit, and attach the DIN rail clip to the plate in the required orientation.
For dimensions with the DINrail clip attached, see DINrail mount dimensions on page36.
Mounting to a Wall or Frame
LMI also provides wall mount brackets to mount the GoMax NX unit directly on a wall or to a frame.
To use the wall mount brackets, remove the DIN rail clip plate from the back of the unit, and attach
the wall mount brackets to the back of the unit using the provided screws. Make sure that the unit is
securely fastened to the wall.
For dimensions with wall mount brackets attached, see Wall mount dimensions on page37.
