Geotab IOX-ANALOG Documentation


For the most up to date version, please visit:

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

Together 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.

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 including limitations of use located following these installation instructions. 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 wiring is limited to a reach of approximately 3.5 feet from the GO device mounting location. Extending the wiring 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 operation of the vehicle.


Start with the Geotab GO device unplugged from the vehicle. Remove the IOX expansion port cover on your GO device.


Plug in the 90° USB connector of the IOX to the GO device. Secure the USB connector using a zip tie, being careful not to over tighten it, thereby possibly damaging the USB connector.

NOTE: The USB connector can only be inserted in one orientation (see image).


Your IOX-ANALOG has four inputs that are configured and labelled as Aux 1–4. Connect the desired auxiliaries in the vehicle to the IOX-ANALOG wires as needed. The IOX-ANALOG will record voltage readings from 0–30 V and will adjust the reporting error based on the range of values it sees. This means that for a smaller range, it will report smaller changes. With a higher range, it will report values when a higher voltage change is detected.


Once your connections to the IOX-ANALOG wiring have been made, connect the GO device and immediately start the vehicle. Your GO device will enter debug mode.


Please verify that the device is communicating correctly. Using a PC or smart phone, navigate to

Fill in your name, company, and the Geotab GO device serial number (found at the bottom of the device) and click on Log Install.


You will now see a screen that displays the current status of the device. If the device is communicating correctly, you will see GREEN lettering with the last valid GPS record. If the text appears in RED, the device is unable to communicate and you must verify the installation.

Termination Shunt IOX V2 Housing.png

You may notice your IOX comes with a termination shunt installed in the expansion port. If you are installing more than one IOX in a daisy chain you will need to remove the shunt from each device in line, with the exception of the last IOX connected. That shunt must remain in the last IOX and should be secured with a zip tie.

The use of the shunt in the last IOX is necessary for the GO Device to detect and configure the IOX as effectively as possible.

NOTE: Failing to install the shunt in the last IOX could affect IOX communication. It is recommended that you secure the shunt using a zip tie if not already done.

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.
