The IOX-ANALOG enables the GO device to read analog signals from a vehicle and its connected accessories.

With MyGeotab, the IOX-ANALOG provides near real-time status information for analog sources and delivers notifications, if readouts fall outside of user-defined values.

Top Features

  • Monitor up to 4 analog inputs
  • Possible uses include:
  • Secondary battery voltages
  • Liquid flow meters
  • Temperature and pressure readings

IOX Installation Instructions

NOTE: Professional Installation Required — Installation of the IOX-ANALOG requires the installer have sufficient technical knowledge and expertise for mobile device installation and integration into modern vehicles, i.e. Certified Geotab® Installer certification or equivalent.

WARNING! Prior to IOX-ANALOG installation, read and follow GO device installation instructions ( to verify any existing GO device installation is correct in preparation for IOX-ANALOG installation. Incorrect installation of either the GO device, and/or IOX-ANALOG can result in loss of vehicle control and serious injury.

WARNING! Prior to IOX-ANALOG installation, read and follow Important Safety Information and Limitations of Use, located at the end of the document. Always read and follow all safety information to prevent loss of vehicle control and serious injury.

Identify and test the connection points for the auxiliaries you wish to monitor. Keep in mind that the IOX wire has a reach of approximately 3.5 feet from the GO device mounting location. Extending the wire to reach some connection points may be necessary. Make the auxiliary connections and secure them using an approved method, such as a T-tap wiring. Ensure none of the components or wiring interferes with the safe vehicle operation.

How to Install IOX-ANALOG


Unplug the Geotab GO device from the vehicle and remove the IOX expansion port cover on your GO device.


Plug the 90° USB connector from the IOX in to 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.


The IOX-ANALOG has four inputs — configured and labelled Aux 1–4. Connect the desired auxiliaries in the vehicle to the IOX-ANALOG wires, as needed. The IOX-ANALOG records voltage readings from 0–30 V and adjusts the reporting error based on the range of values it sees. As a result, the IOX-ANALOG reports small changes for a lower range, and larger changes for a higher range.


Once you connect the IOX-ANALOG to the GO device, plug in the GO device and immediately start the vehicle. The GO device enters debug mode.


Navigate to to verify that the device is communicating. In the space provided, enter your name, the company name, and the GO device serial number — found at the bottom of the device. Click Log Install.


After you click Log Install, the web page displays the current communication status of the device — in GREEN or RED text. If the device is communicating, the status is displayed in GREEN text. If the device is not communicating, the status is displayed in RED text.

Note: If the device is not communicating, please ensure the device is installed correctly and try again.

Termination Shunt IOX V2 Housing.png

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 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 with a zip tie.

Important Safety Information and Limitations of Use

For the latest version of Limitations of Use, please visit: 

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.
