GoMax Smart Vision Accelerator:User Manual 4
Introduction
The GoMax 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 lets you
quickly and easily add powerful data processing to a Gocator system, achieving faster cycle times and
enhancing overall inspection performance.
GoMax provides this compute power thanks to its NVIDIA Jetson TX2’s 256-core GPU and 64-bit quad-
core ARM processor—all in a compact, rugged case.
GoMax does this by taking over a portion of the sensor’s data processing (data generation, 3D
measurement, and control).
Relationship between GoMax (right)and a sensor (left)
GoMax is ideal for accelerating one or more Gocator snapshot sensors such as Gocator 3506, or multi-
sensor, buddied Gocator laser line profile sensor systems. A single GoMax unit can accelerate one or
more sensors.

GoMax Smart Vision Accelerator:User Manual Introduction • 5
GoMax accelerating one or more Gocator sensors
You can also add multiple GoMax units to a system, each unit accelerating one or more sensors, to scale
up to faster speeds. Note however that you can't use multiple GoMax units to accelerate a single sensor.

GoMax Smart Vision Accelerator:User Manual Introduction • 7
The web interface on an accelerated sensor is identical to the interface on an unaccelerated sensor. The
Ethernet-based output protocols (Gocator, EtherNet/IP, ASCII, and Modbus) are also identical to those
found on an unaccelerated sensor, and are fully supported.
GoMax supports digital, analog, and serial output from sensors. However, because output must
be passed to the GoMax unit and then back to the sensor, network latency will have an impact
on performance.
GoMax can accelerate GDKtools in custom firmware, with some limitations (for details, see
Understanding How GDK Tools Work with GoMax on page 32).
For information on developing GDKtools, see the reference documentation and samples provided with
the library.
This documentation describes how to connect and use a GoMax unit. For information on using Gocator
sensors, see the user manuals of those devices.

Safety and Maintenance
The following sections describe the safe use and maintenance of GoMax vision accelerators.
Electrical Safety
Failure to follow the guidelines described in this section may result in electrical shock or equipment
damage.
Sensor systems GoMax are 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 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 vents clean
To avoid overheating of the GoMax unit, make sure the unit's vents are clean.
Environment
Avoid installing the GoMax unit in hazardous environments
To ensure reliable operation and to prevent damage to the GoMax unit, avoid installing the unit in
locations
lthat are humid, dusty, or poorly ventilated;
lwith a high temperature, such as places exposed to direct sunlight;
lwhere there are flammable or corrosive gases;
lwhere the unit may be directly subjected to harsh vibration or impact;

GoMax Smart Vision Accelerator:User Manual Safety and Maintenance • 9
lwhere water, oil, or chemicals may splash onto the unit;
lwhere static electricity is easily generated.
Ensure that ambient conditions are within specifications
GoMax units are suitable for operation between 0–45° C.

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 supplied power supply with the GoMax unit. Using a higher voltage power supply
will damage the unit. Take particular care not to use a Master 100 power supply with GoMax, as
the barrel connector is identical.
LMIrecommends powering up the GoMax unit and performing the initial configuration of the GoMax
unit before physically connecting the unit to the sensor system.
To connect power:
1. Connect the power supply connector to the unit and hand-tighten.
2. Plug the power adapter into an available electrical outlet.

The unit is ready for initial configuration (setting an IPaddress).

GoMax Smart Vision Accelerator:User Manual Adding GoMax to a Sensor System • 14
Setting the IP Address
Each GoMax unit and Gocator sensor on the sensor system network must have a unique IP address. By
default, GoMax units are set to an IP address of 192.168.1.6. If this address does not conflict with other
GoMax units or Gocator sensors on the network, you can leave its IPaddress as its default, and use that
address to connect to the GoMax unit later on.
If this address conflicts with sensors in your sensor system, or if your system will contain multiple
GoMax units, you will have to set the IPaddress of each GoMax unit to avoid conflicts. Follow the steps
described in Setting the IP Address above
To set the IP address of a GoMax unit:
1. Using an Ethernet cable, connect a computer to the ETH 1 port on the GoMax unit.
2. On the computer, launch an Internet browser and navigate to 192.168.1.6.

Mounting
GoMax provides mounting holes on the back and on three sides of the unit. Although you can mount
GoMax using any of these holes and in any orientation, to avoid overheating, LMI recommends the
following:
lThe ventilation holes should be kept free of obstructions. (There are two vents on opposite sides of
the unit.)
lThe larger vent (18 holes with anti-dust mesh) should be at the bottom.
You can mount GoMax units to a DINrail or directly to a frame.
For details on GoMax's mounting holes, see GoMax on page 35.
Using DIN Rail Clips
LMI provides two DIN rail clips to mount GoMax on a DIN rail. Note the recommended orientation
(smaller vent at the top) in the following illustration:
Mounting Directly to a Frame
You can also mount the GoMax unit directly to a frame. All mounting holes are specified as M4X0.7 - 6H,
with a thread depth of 3.65 mm. The same recommendations for orientation and mounting points (see
above)still apply if you mount GoMax directly to a frame.

GoMax Smart Vision Accelerator:User Manual Adding GoMax to a Sensor System • 18
