IOX-WRKS: Winter solution
0 mins to read•
Learn how to install a GO device in your winter operations vehicle using the IOX-WRKS works solution. The Geotab winter solution integrates with solid and liquid material controllers, temperature monitoring equipment and telematic inputs to make real-time data and structured reporting accessible in MyGeotab. This installation requires an installer with both a Geotab Installer Certification and a Geotab Winter Solutions Certification.
Geotab® integrates with a wide selection of material spreader equipment to offer a complete winter solution.
The Geotab winter solution integrates with solid and liquid material controllers, temperature monitoring equipment, and telematic inputs. Telemetry data is sent through the GO device, and can be accessed in real-time, or via structured reports for operations management.
Installing the winter solution requires that the installer has sufficient technical knowledge and expertise with the GO device. In addition, the installer must have a Geotab Installer Certification and a Geotab Winter Solution certification.
The reseller is responsible for ordering the Winter Solution product and for providing a vehicle list with specific winter-related details for each vehicle: spreader make and model, temperature monitoring equipment (if any), plow sensor type and installed location, and any other required telemetry inputs.
The reseller also must select the professional installer, ensure that they have Winter Solution installation training and certification, and maintain installation compliance.
For more information, refer to the Public Works Getting Started Guide for Resellers
Geotab will ship the Winter Solution product to the Customer, and provide Winter Solution installation training, guides, and instructions.
The Customer must ensure that listed vehicles and winter solution products are available for installation. They must also weld sensor brackets and install hydraulic sensors as needed.
The installer is responsible for obtaining Winter Solution installation training and certification, installing the Winter Solution product according to Geotab standards, and calling Geotab Public Works/ Winter Solution support to have configurations loaded and telemetries verified.
Geotab Public Works / Winter Solution support: 1-800-984-6175 M-F 7:30am - 8pm Eastern Time. Saturday by appointment with 2 days advance notice.
Correct input mapping for telemetry is crucial for winter installations. Failure to adhere to input mapping will result in erroneous data and winter reports will not function as intended.
When installing only a GO Device with IOX-AUXM. Specifically, vehicles without automatic material spreaders that do not require the IOX-WRKS installation. Installation of a single IOX-AUXM will require the loop to be cut to obtain inputs AUX5-8 for winter specific telemetries.
When installing the IOX-WRKS, inputs are pre-mapped to AUX 5 - AUX 8 respectively. Using an IOX-AUXM for additional inputs requires the loop to NOT be cut to maintain its AUX 1 - AUX 4 configuration.
IGN_BATT (+12V 650mA max) provided ignition power for sensors
GND provided ground for sensors
AUX5 - Belly plow or Manual Spreader
AUX6 - Front Plow
AUX7 - Wing Plow
AUX8 - Tow Plow or Beacon
Additional telemetries using AUX1-4 can be used for winter installations not listed in the input mapping. To configure the IOX-AUXM cable for inputs 1-4, DO NOT cut the loop. More information regarding the IOX-AUXM cable can be found here.
! IMPORTANT: To ensure an IOX accessory is recognized, it must be plugged into the GO device (or the IOX chain) before plugging in (powering up) the GO device.
For approximately 30 minutes after powering on the GO device (all 3 LEDs flash and 6 swift beeps are heard), the device enters debug mode, and attached IOX-AUXM(s) enter input learning mode.
While in learning mode, the GO device beeps X times for each change in state where X is the AUX number. For example, if the Front Plow is moved from the stowed to the plowing position, the GO device will beep 6 times and again 6 times when moved from the plowing to stowed position.
Standard Winter Solution installations involve a GO device and a T-harness.
However, note that some installations (such as purpose-built or adapted yellow iron) require the use of a 3-wire harness (HRN-RW03S4, or HRN-CW03S3) instead of a T-harness. Such vehicles may also require different mounting locations.
Any IOX installations or hardware integrations must be done prior to connecting the GO device to the vehicle ECM port. To ensure that the installation is efficient and organized, and to keep cable extensions down to a minimum, the installer should consider the location of all required telemetry inputs and material spreader ports before installing. Installation instructions can be found in the following document: IOX-WRKS Install Guide.
✱ NOTE: The IOX-WRKS is only compatible with GO9 or GR9 devices. It is not compatible with older GO or GR device versions.
Mounting sensors typically involves welding or hydraulics. Attempting to perform these operations without proper training and knowledge can lead to injury or death. Please obtain professional installation services from trained technicians with welding and/or hydraulic certification.
When mounting sensors, it is the client’s responsibility to provide direction and support to ensure that the sensors are mounted in optimal locations that do not interfere with normal maintenance and operation. It is advisable to always mount proximity sensors perpendicular to the moving equipment so that the sensor does not get impacted or damaged.
Sensors should always be configured to be active when the equipment is being operated. An example would be active when the plow is down, or when the manual spreader is actively applying material. This configuration helps reduce telemetry errors and maintains uniformity in winter operations reports.

Winter vehicles operate in a highly corrosive environment. Use the following guidelines to reduce corrosion.
All in-cab wiring connections should be soldered and protected with heat shrink or tape. All external wiring connections must be soldered and weather-proofed using heat shrink or self-fusing tape. Dielectric grease must be applied to all proximity sensor connectors, both internally and externally.
While there are many manufacturers and suppliers of material spreaders, all are designed to apply various materials (brine, salt, sand) to the road surface to improve drivability. This is usually done via Pulse Width Modulation (PWM) control of the hydraulic valves. Most modern controllers feature the ability to connect to a data logging port, where the controller data can be captured and recorded. Older or more basic models may not have a data port. For such controllers, a manual (usually hydraulic) sensor is required to capture material usage data.
When interfacing with these controllers, it is important to use the correct software configuration, controller firmware, and cabling. Some controllers require specific settings or port configurations beyond any firmware updates. Also, to confirm data flow, some controllers require a specific event change, or for simulation mode* to be activated.
✱ NOTE: Simulation mode, or SIM, is a manual setting on controllers that can be used to confirm data flow. Material totals will not accumulate due to the nature of how SIM mode functions.
The following documents and videos are provided by Geotab to assist installers and clients with the interfacing process. Additional assistance may be obtained from your equipment upfitters or suppliers.Please ensure that you familiarize yourself with the appropriate controller document or video before performing an installation or servicing:dd controller videos
