IOX Installation Instructions
✱ NOTE: Professional Installation Required — Installation of the IOX-OUTPUTM 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-OUTPUTM installation, read and follow GO device installation instructions (goo.gl/rkLRiA) to verify that any existing GO device installation is correct in preparation for IOX-OUTPUTM installation. Incorrect installation of either the GO device, and/or IOX-OUTPUTM can result in loss of vehicle control and serious injury.
WARNING! Prior to IOX-OUTPUTM 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.
How to Install IOX-OUTPUTM
Unplug the Geotab GO device from the vehicle and remove the IOX expansion port cover on the 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 may damage the USB connector.
Note: Insert the USB connector in the orientation displayed in the image.
The IOX-OUTPUTM has two wires: a relay driver output wire and a ground wire. The ground wire connects to the vehicle ground, while the relay driver output wire connects to the relay coil terminal. For more detailed installation instructions, please refer to the Installation Diagram on page 4.
Once you connect the IOX-OUTPUTM to the GO device, plug in the GO device and immediately start the vehicle. The GO device enters debug mode.
Navigate to installmygps.com 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 displayed 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.
SDK Add-In Example
For testing and verification, Geotab developed a custom Add-In for the IOX-OUTPUTM. The custom Add-In allows you to trigger the IOX-OUTPUTM on or off. Please visit the MyGeotab SDK to download the IOX-OUTPUTM Add-In.
IOX-OUTPUTM Detailed Instructions
Connect the black wire of the IOX-OUTPUTM to the vehicle's ground.
Connect the white wire of the IOX-OUTPUTM to one side of the relay coil.
Connect the other side of the relay coil to the positive terminal of the vehicle's battery.
Connect wires from the relay switching contacts to the load as required.
For a 12 V relay, use a coil impedance greater than 80 ohms.
For a 24 V relay, use a coil impedance greater than 160 ohms.
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: 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

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.
