Learn more about IOX-CAN, which integrates third-party data with MyGeotab software, allowing supplementary fleet data collection and consolidation of data in one place. Using the IOX-CAN, Customers and Partners can also transmit data through the Geotab GO device using the Third-Party Data Protocol on our private CAN Bus.
Interfacing with third-party devices
The IOX-CAN integrates third-party data with the MyGeotab™ software — allowing supplementary fleet data collection and consolidation in one place.
Customers and Partners can also transmit data through the Geotab® GO™ device using the Third-Party Data Protocol (my.geotab.com/sdk) on our private CAN Bus via the IOX-CAN. No initial handshake is required. If third-party data is in the correct format, the GO device begins processing and transmitting the data to MyGeotab.

Third-Party Interface Current Output Limit
All GO7® and newer devices and variants
GO9® can source a maximum total current to the IOX™ in Daisy Chain
2500 mA at 12 V/24 V
✱ NOTE: For each IOX in the Daisy Chain, add the Max Current draw, and do not exceed the Max.Total IOX Current draw.
✱ NOTE: When installed in a vehicle, The IOX-CAN and third-party devices derive the supply voltage level from the car battery. IOX-CAN is not suitable for direct connection to an engine bus.
The third-party CAN interface adjusts its baud rate based on the baud rate of the connected CAN bus (either 250 kbps or 500 kbps). The IOX-CAN must receive a minimum of one message to set the baud rate. Shorting jumper pin A and jumper pin B together enables the internal 120 Ohm terminating resistor — required if the application itself is not already terminated.
! 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 Geotab GO device from the vehicle and remove the IOX expansion port cover on the GO device.
Connect the third-party device to the 6-pin Molex connector on the IOX-CAN.
WARNING! The molex 6-pin connector of the IOX-CAN must ONLY connect to a third party device. Connecting the molex 6-pin connector to a vehicle's internal communication network may cause interference, resulting in unexpected vehicle behavior, vehicle damage and/or serious personal injury or death.
Plug the 90° USB connector from the IOX in 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.
Once you connect the IOX-CAN to the GO device, plug in the GO device and immediately start the vehicle. The GO device will enter debug mode.
Navigate to myinstallpub.geotab.com to verify that the device is communicating.
✱ 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 connected. The shunt must remain in the last IOX and secured with a zip tie.
The shunt in the last IOX device ensures the GO device detects and configures the IOX, as effectively as possible.
✱ NOTE: Failure to install the shunt in the last IOX may affect IOX communication. To ensure the IOX communicates, please secure the shunt using a zip tie.
To log temperature every five minutes from the Valor TempTrac solution, apply the following custom parameter to the GO device using the MyGeotab software:
<GoParameters><Parameter Description=" Log Reefer Temp Periodically" Offset="180" Bytes="02"/></GoParameters>
This functionality requires GO device firmware XXX.20.43 or higher.

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.
NOTICE: This product does not contain any user-serviceable parts. Configuration, servicing, and repairs must only be made by an authorized reseller or installer. Unauthorized servicing of these products will void your product warranty.
