IOX Installation Instructions

NOTE: Professional Installation Required — Installation of the IOX-RS232 requires the installer to have sufficient technical knowledge and expertise for mobile device installation and integration into modern vehicles. i.e. Certified Geotab Advanced Installer certification.

WARNING! Prior to IOX-RS232 installation, read and follow GO device installation instructions (goo.gl/rkLRiA) to verify any existing GO device installation is correct in preparation for IOX-RS232 installation. Incorrect installation of either the GO device, and/or IOX-RS232 can result in loss of vehicle control and serious injury.

WARNING! Prior to IOX-RS232 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-RS232

1

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

2

Plug the 90° USB connector from the IOX into the GO device. Secure the USB connector using a cable tie.

NOTE: Insert the USB connector in the orientation displayed in the image.

NOTE: Over tightening the cable tie may damage the USB connector.

3

Choose an appropriate mounting location for the RS232 accessory.

✱ NOTE: The location you choose for the GO Device influences the locations available to mount the accessory due to the wire length on the IOX-RS232. Please ensure the installation does not interfere with safe vehicle operation.

4

Connect the third-party device to the IOX-RS232 using the DB9 Female or Male connector (IOX-RS232F , IOX-RS232M) or Delphi connector (IOX-RS232D).

5

The external red and black wires on the IOX-RS232 are used to supply power to a third-party device. The red wire connects to device power, and the black wire connects to device ground.

WARNING! The red and black IOX-RS232 wires are powered when the GO device is on. If they are not being used, ensure they are properly insulated to prevent any electrical hazard.

WARNING! Connecting the IOX-RS232 red and black wires to any vehicle power source may cause electrical heat/fire damage to the GO device, vehicle and/or serious burn injury. IOX-RS232 red and black wires must only be connected to provide power to a third-party device load.

6

Once you connect the IOX-RS232 to the GO device, plug in the GO device and immediately start the vehicle. The GO device enters debug mode.

7

Navigate to myinstallpub.geotab.com to verify that the device is communicating.

  • In the Installer information section, enter the installer’s name and company name. Select the next section.
  • In the Device serial number section, enter the 12-digit alphanumeric serial number, located on the bottom of the device, then click Validate. Select the next section.
  • In the Device status section, review the status of the device. The PASS status indicates the device communicated with the network in the last 24 hours. The FAIL status indicates the device has not communicated with the network in the last 24 hours. Select the next section.
  • In the Vehicle section, enter the vehicle-related information.

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

Termination Shunt

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, except for the last IOX connected. The shunt must remain in the last IOX and secured with a cable 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 cable tie if not already done.

Important Safety Information and Limitations of Use

For the latest version of Limitations of Use, please visit: goo.gl/k6Fp0w.

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 cab 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.
