! 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.
WARNING! Always read and follow all safety information, including Important Safety Information and Limitations of Use, before harness and/or IOX installation. Disconnect the GO device from the vehicle before installation and connect it post-installation (see goo.gl/rkLRiA). Failure to follow these instructions and warnings can result in loss of vehicle control and serious injury or vehicle damage.
Identify and test the connection points for the auxiliaries you wish to monitor. Please note, the IOX wire has 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 T-tapping. Ensure none of the components or wiring interferes with the safe operation of the vehicle.
1 | Unplug the GO device from the vehicle and remove the IOX expansion port cover on your GO device. | |
2 | Plug the 90° USB connector from the IOX into 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. | |
3 | The IOX-AUXM has four inputs — configured and labeled Aux 1–4. Connect the desired auxiliaries in the vehicle to the IOX-AUXM wires, as needed. If more than four auxiliaries are required please refer to Expanding your IOX-AUXM. Aux 1 = Blue Aux 2 = Orange Aux 3 = Green Aux 4 = White | |
4 | Once you connect the IOX-AUXM to the GO device, plug in the GO device and immediately start the vehicle. The GO device will enter debug mode. | |
5 | While the GO device is in debug mode, trigger each auxiliary one at a time so the IOX-AUXM learns the inputs. Once the IOX-AUXM learns an input, the GO device emits a number of beeps corresponding to the auxiliary number. For proper configuration, you must hear the beeps when the auxiliaries are triggered both ON AND OFF (e.g. Aux 2 sounds two beeps when triggered ON and then two beeps when triggered OFF). Repeat this step until the corresponding beeps are heard on BOTH trigger ON and trigger OFF. | |
6 | 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-AUXM can expand from four to eight auxiliaries by plugging in a second IOX-AUXM to the expansion port of the first and following the steps below.
✱ NOTE: You must remove the zip tie from the original IOX-AUXM.
In order for the second IOX-AUXM to report as AUX 5-8, follow the steps below:
1 | Locate the red and black loop, also known as Short. |
2 | Cut the wires to configure the IOX-AUXM to act as Aux 5-8. |
3 | Secure both IOX-AUXMs with a zip tie. |
Aux 5 = Blue | Aux 6 = Orange | Aux 7 = Green | Aux 8 = White |
✱ NOTE: By cutting the loop, the second IOX-AUXM always reports as AUX 5-8, regardless of whether an AUX 1-4 is installed. The loop must be cut before connecting the IOX to the chain.
The IOX-AUXM uses a learning algorithm to determine the circuit type — listed below — to which the IOX-AUXM is connected:
The learning algorithm described above can be disabled using custom parameters in MyGeotab.
To manually configure custom parameters, follow the steps provided in this Community article.
<GoParameters><Parameter Description="Use Aux Config For IOX" Bytes="02" Offset="66"/></GoParameters>
The two digits for Bytes in the custom parameter above mean:
Apply the following custom parameter to manually configure an auxiliary to operate with the three circuit types listed above:
<GoParameters><Parameter Description="GND-Batt Config for Aux 4-IOX" Bytes="00" Offset="48"/></GoParameters>
The two digits for Bytes in the custom parameter above is an 8-bit long hexadecimal number that corresponds to an AUX number ranging from 1 to 8 (i.e. the number of digital auxiliaries that a GO device monitors). A value of 0 configures the corresponding auxiliary into Ground-High or Float-High configurations, while a value of 1 configures the auxiliary to detect a Ground-Float circuit — explained further in the following example.
In this example, the following custom parameters are applied to configure auxiliaries 2, 6, and 8 to a Ground-Float circuit, and the remaining auxiliaries to Ground-High or Float-High:
<GoParameters><Parameter Description="Use Aux Config For IOX" Bytes="02" Offset="66"/></GoParameters>
<GoParameters><Parameter Description="GND-Batt Config for Aux 4-IOX" Bytes="A2" Offset="48"/></GoParameters>
✱ NOTE: In the second custom parameter, the value of A2 in the bytes section instructs the IOX-AUXM to put auxiliaries 2, 6, and 8 into a Ground-Float circuit configuration. As mentioned above, the value entered in the bytes section is a hexadecimal number. The value of A2 is equivalent to 10100010 in binary. The first digit from the right represents auxiliary 1, the second digit from the right represents auxiliary 2, and so on. Since the digits that represent auxiliaries 2, 6, and 8 have a value of 1, the IOX-AUXM is instructed to place auxiliaries 2, 6, and 8 into a Ground-Float circuit configuration.
You can invert any of the eight auxiliaries in MyGeotab. When auxiliaries are inverted in MyGeotab, the auxiliary reports the opposite of what the GO device logs. For example, if auxiliary 1 is inverted and the device reports a 1 (or true), MyGeotab reports a 0 (or false). If an auxiliary is inverted, the button is highlighted in dark blue. To invert auxiliaries, follow the steps below:
1 | Navigate to Vehicles & Assets and select an asset. |
2 | Click the Settings tab and open the IOX & Auxiliaries section. |
3 | Identify the AUX# and turn on the Invert input value toggle. |
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. A maximum of 4 IOXs can be daisy chained for GO6 devices. GO7 and newer devices allow up to 5 IOXs in total.
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.

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.
