Gocator Line Confocal Sensors: User Manual 12
Introduction
This documentation describes how to connect, configure, and use a Gocator 5500 series line
confocal sensor ("G5 sensor"for short)using the GoPxLsoftware. Although you can run the software
on-sensor, with G5 sensors, LMIstrongly recommends running sensors through a PCinstance of
GoPxL.
Before using a sensor, you should familiarize yourself with sensor safety and maintenance. For
more information, see Safety and Maintenance on page13.
For a breakdown of this documentation, see Using the Manual on page15.
The documentation applies to the following:
lGocator 5500 series
lGoMax NX
lX64-based PC (Intel/AMD) running Windows 10 (for running GoPxLon a PC)
GoPxLonly supports GoMax NX, not the pre-NXversion.
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.

Gocator Line Confocal Sensors: User Manual 13
Safety and Maintenance
The following sections describe the safe use and maintenance of Gocator sensors.
Electrical Safety
Failure to follow the guidelines described in this section may result in electrical shock or
equipment damage.
Sensors should be connected to earth ground
All sensors 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 a suitable power supply
The power supply used with sensors should be an isolated supply with inrush current protection or
be able to handle a high capacitive load. Verify the voltage input requirements for your sensor in the
sensor's specifications; for specifications, see Sensors on page800.
Use care when handling powered devices
Wires connecting to the sensor should not be handled while the sensor is powered. Doing so may
cause electrical shock to the user or damage to the equipment.
Handling, Cleaning, and Maintenance
Dirty or damaged sensor windows (emitter or camera) can affect accuracy. Use caution when
handling the sensor or cleaning the sensor's windows.
Devices are heavy
Due to the weight of Gocator line confocal sensors, LMI recommends that two people mount the
devices.
Keep sensor windows clean
Use dry, clean air to remove dust or other dirt particles. If dirt remains, clean the windows carefully
with a soft, lint-free cloth and non-streaking glass cleaner or isopropyl alcohol. Ensure that no
residue is left on the windows after cleaning.

Gocator Line Confocal Sensors: User Manual Safety and Maintenance •14
Avoid excessive modifications to files stored on the sensor
Sensor settings are stored in flash memory inside the sensor. Flash memory has an expected lifetime
of 100,000 writes. To maximize lifetime, avoid frequent or unnecessary file save operations.
Environment and Lighting
Avoid strong ambient light sources
The imager used in this product is highly sensitive to ambient light. Do not operate this device near
windows or lighting fixtures that could influence measurement or data acquisition.If the unit must be
installed in an environment with high ambient light levels, a lighting shield or similar device may
need to be installed to prevent light from affecting measurement.
Avoid installing sensors in hazardous environments
To ensure reliable operation and to prevent damage to sensors, avoid installing the sensor 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;
lwhere water, oil, or chemicals may splash onto the unit;
lwhere static electricity is easily generated.
Ensure that ambient conditions are within specifications
The sensor operating temperature range is 15 to 35 °C.
For all sensors, the storage temperature is -30 to 70 °C.
For all sensors, relative humidity (non-condensing) is 25% to 85%.
The sensor must be heat-sunk through the frame it is mounted to. When a sensor is properly
heat sunk, the difference between ambient temperature and the temperature reported in the
sensor's health channel is less than 15° C.
Sensors are high-accuracy devices, and the temperature of all of its components must therefore
be in equilibrium. When the sensor is powered up, a warm-up time of at least one hour is
required to reach a consistent spread of temperature in the sensor.

Gocator Line Confocal Sensors: User Manual 16
Gocator Overview
Gocator 5500 series sensors (also called G5 sensors)are 3D smart line confocal imaging (LCI)
sensors. These sensors simultaneously produce 3D topography, 3D tomography, and 2D intensity
data. The sensors can scan a wide variety of material types, including multi-layered,
transparent/translucent, curved edge, shiny/specular, high-contrast textured, or mixed materials. G5
sensors uses a dual-axis optical system that improves noise immunity and provides higher signal
quality. This makes it possible to scan difficult surfaces and very fine features.
Gocator 5500 sensors simultaneously generate 3D topography for each layer of a material, making it
possible to measure the thickness of individual layers or detect defects on secondary layers.
G5 Sensors are configured through an easy-to-use web-based interface called GoPxL, which provides
built-in measurement tools, I/O connectivity, and multi-layer profiling support. Although GoPxL can
run on-sensor, with G5 sensors the frequency is limited. Therefore, in most G5 applications, you will
configure and run G5 sensors through the PC-based version. GoPxLrunning on a sensor and on a
PCis almost identical.
Before using sensors, see Safety and Maintenance on page13.

Getting Started
The following sections provide hardware and system overviews and describe installation and initial
networking setup procedures.
Sensor Part Numbers
Use the following to understand sensor part numbers:
Upgrading from Gocator Firmware
If you are upgrading your sensor from Gocator firmware 6.2 or earlier to GoPxL, and you have
created pattern files using Surface Pattern Matching or track files using Surface Track in the Gocator
firmware, be sure to add instances of those tools and remove those files manually. These files can
take up considerable space.

Hardware Overview
The following sections describe Gocator and its associated hardware.
Gocator Cordsets
Gocator sensors use two types of cordsets:the Power & Ethernet cordset and the I/Ocordset.
When connecting cordset connectors to the sensor's connectors, do not exceed a torque of 2
Nm (18 in-lbs). Ensure that you properly secure the cordset cabling to avoid stress loading on
the sensor connectors.
The Power & Ethernet cordset provides power and Ethernet sensor communication via 1000 Mbit/s
Ethernet with a standard RJ45 connector.
Note that Gocator 5500 Line Confocal Sensors use a series-specific Power & Ethernet cordset (the
High Power &Ethernet cordset). Cordsets with part numbers 301237-5m and 301238-5m are 48-volt
only.
The I/O cordset provides digital I/O connections, an encoder interface, RS-485 serial connection, and
an analog output.
The maximum cordset length is 60 m.
For information on the I/Ocordset's pinout, see Gocator I/O Connector on page813.
For information on the HighPower & Ethernet cordset, see Gocator Power/LAN Connector on
page811.

Digital Output Provides digital output.
See Master 100 on page818 for pinout details.
Master 810 / 2410
The Master 810 and 2410 network controllers let you connect multiple sensors to create a multi-
sensor system:
lMaster 810 accepts up to eight sensors
lMaster 2410 accepts up to twenty-four sensors
Both models let you divide the quadrature frequency of a connected encoder to make the frequency
compatible with the Master, and also set the debounce period to accommodate faster encoders. For
more information, see Configuring Master 810 on page27. (Earlier revisions of these models lack the
DIPswitches.)
