! IMPORTANT: Professional installation (Certified Geotab® Installer or equivalent) is required for the safe and proper installation of this product (harness and/or IOX). The installer must have sufficient technical knowledge and expertise for the respective installation.
Unplug the GO device from the vehicle and remove the IOX expansion port cover on your GO device.
Plug the 90° USB connector from the IOX-WRKS into the GO device. Secure the USB connector using a zip tie. Please note that over tightening the zip tie may damage the USB connector.
✱ NOTE: Insert the USB connector in the orientation displayed in the image.
To interface with Material Spreaders or Temperature Sensing equipment, use the primary port. The secondary DB9 port is only used to connect a temperature device when the primary port is connected to a controller.
Spreader integration documentation is available here.
To interface with Parker, Muncie, Genesis, and Marwis systems, use the CAN bus connection.
Spreader integration documentation is available here.
Connect telemetries from the vehicle to the inputs (labeled AUX 5 to AUX 8) on the IOX-WRKS, following the required input mapping. If more than four inputs are required, an additional IOX-AUXM can be added for AUX 1 to AUX 4. Do not cut the loop if adding this cable.
The inputs are color-coded as the following:
! IMPORTANT: DO NOT CONNECT IGN_BATT OR GND TO VEHICLE POWER!
The IOX-WRKS receives its power from the GO device. Connecting the IGN_BATT or GND wires on the IOX-WRKS to vehicle power can result in damage to the IOX-WRKS and the GO device, and may void the warranties of both.
The purpose of the IGN_BATT and GND wires on the IOX-WRKS is to provide a convenient power connection point (power OUT) for external sensors, such as plow or spreader sensors. Click here for more details.
IGN_BATT and GND are available to provide power/ground to sensors (650mA max load). Do not connect to vehicle power or ground!
Required input mapping:
Connect any additional IOX cables and daisy chain them together using the termination shunts. The termination resistor must remain in the shunt of the last cable. Once all IOX cables are connected to the GO device, plug in the GO device and immediately start the vehicle. The GO device enters debug mode — indicated by six short beeps. Please allow 3 to 5 minutes for the device to wake, establish connectivity, and update firmware before proceeding to the next step.
Once the device is ready — the red, green, and blue LEDs are solid and the device is no longer beeping — configure the IOX-WRKS, and test all data and telemetry inputs.
Once the GO device has power and before setting a spreader configuration, Connect the LED add-on to the IOX-WRKS USB cable. The LED will be blinking indicating that the IOX-WRKS has power. For more information on the LED blinking patterns refer to the following document: IOX-WRKS LED Installer Guide.
✱ NOTE: The IOX-WRKS will not function until a material spreader specific configuration is loaded. It is absolutely necessary to call support for this process, and to verify data flow and each telemetry to complete the install.
If the IGN_BATT wire is used in step 4 above, you must inform Geotab Support of this information so they can turn on this wire with an extra command (Provisioning Step 12).
Geotab Public Works / Winter Solution support: 1-800-984-6175 M-F 7:30am - 8pm Eastern Time. Saturday 11am - 7pm Eastern Time.
Public Works Support will assist in setting the spreader controller configuration.
After a spreader configuration has been successfully set, the IOX-WRKS LED will show a solid light.
After you see the solid light, set the material spreader into the SIM/Operation Mode — as described in the spreader specific documentation. Trigger and verify each input, one at a time with support.
Once the locators have been properly tested and configured, ensure all cables are safely secured with a cable tie, place the dash panels in their original positions, and clean the cab so it is ready for the customer.
✱ NOTE: If the device is not communicating, please ensure the device is installed correctly and try again.
The IOX comes with a termination shunt installed in the expansion port. If you plan to install more than one IOX in a daisy chain, you must remove the shunt from each device in the line, with the exception of the last IOX, where the shunt must be kept in place and secured with a zip tie.
✱ NOTE: Failure to install the shunt in the last IOX may affect IOX communication.

WARNING! Do not attempt to install, configure, or remove any product from any vehicle while the vehicle is in motion or otherwise in operation. All installation, configuration, or removal must be done only in stationary vehicles which are securely parked. Attempting to service units while being operated could result in malfunctions or accidents, leading to death or serious personal injury.
WARNING! All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, including gas, brake and clutch pedals. You must inspect devices and cabling on a regular basis to ensure all devices and cabling continue to be securely attached. Loose cabling or devices may impede the use of vehicle controls, resulting in unanticipated acceleration, braking or other loss of vehicle control, which could lead to death or serious personal injury. Improperly fastened in-vehicle devices may detach and impact operators upon sudden acceleration or deceleration, which may cause injury.
WARNING! If at any point after an in-vehicle device is installed a warning light illuminates on the vehicle dash or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device, and contact your reseller. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control, and serious injury.
WARNING! Your in-vehicle devices must be kept clear of debris, water, and other environmental contaminants. Failure to do so may result in units malfunctioning or short-circuiting that can lead to a fire hazard or vehicle damage or serious injury.
WARNING! Do not attempt to remove the devices from the vehicle in which they are originally installed for installation in another vehicle. Not all vehicles share compatibility, and doing so may result in unexpected interactions with your vehicle, including sudden loss of power or shutdown of the vehicle’s engine while in operation or cause your vehicle to operate poorly or erratically and cause death or serious injury and/or vehicle damage.
