Introduction

This document is the IOX-UREADER installation guide. This document provides technical information, installation instructions, and the procedure to locate a vehicle's CAN bus.

Installation with a tachograph

IOX-UREADER allows the GO™ device to read and download real-time data from digital tachographs. This data can then be viewed and analyzed in the Geotab Tachograph Module for the MyGeotab™ platform.

! IMPORTANT: IOX-UREADER is compatible with all tachograph brands. However, the tachograph must support remote download (RDL) functionality. For further information, refer to the Remote Download (RDL) Capability section.

Key features

1. Provides automated remote downloads of vehicle and driver information,
2. Provides automatic driver identification that matches the individual driver with a specific vehicle and improves report accuracy on MyGeotab platform,
3. Facilitates on-demand downloads (in accordance with the technical and legal requirements set by the European Union), and downloads preformed on regularly scheduled intervals,
4. Sends real-time tachograph data, including driver name, driver status, and other useful information (in accordance with the technical and legal requirements set by the European Union) to your MyGeotab database, and
5. Supports a direct connection to the vehicle CAN bus to read vehicle data without electrical contact, and prevent vehicle interference. It auto-detects polarity, baud rate and CAN bus protocol without the need for configuration. (Beta/limited functionality).

Preparing for installation

✱ NOTE: To ensure the proper communication with the device, it is strongly recommended to ensure the GO device has been assigned to the customer’s database prior to the installation.

Installation instructions

✱ NOTE: Professional Installation Required — Installation of the IOX-UREADER requires the installer to have sufficient technical knowledge and expertise for mobile device installation and integration into modern vehicles, such as a Certified Geotab^® Installer certification or equivalent.

! IMPORTANT: The GO device must be disconnected from the vehicle prior to installation. Following installation, you must read and follow Important Safety Information and Limitations of Use for this harness/IOX. Additionally, you must read and follow all Instructions and Warnings to prevent serious injury and/or vehicle damage.

WARNING! It is highly recommended not to create any electrical (vehicle harness modification, splices etc..) or non electrical (CAN clamp) connection between the Geotab devices (GO9 + IOX-UREADER) and the tachograph ports A and B (for example, power supply through the 3-wire harness or CAN bus connection). The Geotab Truck Solution is not designed to interface with these ports, and Geotab will not be responsible for any mechanical, electrical, or legal issues caused by a connection made to tachograph ports A and B.

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

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

WARNING! You must unplug the GO device from the OBD Port before plugging in or unplugging any IOX accessories. Failure to do so may permanently damage the GO device or the IOX.

Termination shunt

The IOX-UREADER 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, secured with a cable tie. The shunt in the last IOX ensures that the GO device detects and configures the IOX as effectively as possible.

IOX-NULL

HRN-TNULL

! IMPORTANT: The operations mentioned above must be done with the IOX-UREADER switched off.

✱ NOTE: Failure to install the shunt in the last IOX may affect IOX communication. To ensure that the IOX communicates, please secure the shunt with a cable tie.

Tachograph connections

Tachographs have four ports: A (WHITE), B (YELLOW), C (RED), and D (BROWN).

✱ NOTE: The four ports are polarized/keyed and will only fit into the mating receptacle as explained. Do not force fit.

✱ NOTE: Some tachographs are protected with a security seal that must be removed in order to proceed with the installation.

✱ NOTE: If installing in a Scania vehicle and the C connector (RED) is populated with wires in positions C5 and C7, and there are no wires connected to A4 and A8, see Scania Vehicles with Tachograph SRE6.x before installation.

✱ NOTE: If installing in a vehicle using Stoneridge SRE8.X or EFAS-4.10 tachograph and the C connector is being used by DSRC antenna, see How to connect CAN-C when it is occupied by the DSRC antenna before installation.

! IMPORTANT: The vehicle electronics are connected to the Tachograph by a pair of wires known as CAN-A (CAN bus), connected to the Tachograph Port-A (WHITE Connector), using the A4 and A8 pins. Never alter the connections in the A or B connectors.

! IMPORTANT: Do not modify the provided C connector (RED). This connection cannot be shared, and there must never be multiple connections as this can cause interferences in the vehicle CAN Bus, which could result in malfunctions.

WARNING! If, at any point, a warning light illuminates on the vehicle dashboard or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device and contact Support. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control and serious injury.

! IMPORTANT: After extracting the Tachograph, be very careful when leaving the tachograph hanging to avoid any cable damage.

First connection — Real-time data

The first connection is made to the Port-D of Tachograph, only the D8 pin (K-LINE signal) is used by IOX-UREADER.

Follow these instructions depending on your installation use case:

Case 1: Tachograph Port D is available

1. Disconnect the brown connector from Port D of the tachograph.
2. Connect the HRN-URTACHO (discontinued) blue wire terminal to position 8.
3. Reconnect the brown connector to Port D of the tachograph.

Using harness HRN-URTACHO02-A

1. Disconnect the vehicle’s connector from Port D of the tachograph.
2. Connect the HRN-URTACHO02-A brown connector to Port D of the tachograph.
3. Connect the vehicle’s connector to the other brown connector on HRN-URTACHO02-A.

Case 3: A brown connector is already connected to tachograph Port D and the connector’s position 8 is not available

Using harness HRN-URTACHO (discontinued)

1. Cut the blue wire terminal of HRN-URTACHO (discontinued).
2. Using a T-splice, connect this blue wire in parallel to the existing wire in Port D position 8.

Using harness HRN-URTACHO02-A

1. Disconnect the vehicle’s connector from Port D of the tachograph.
2. Connect the brown connector on HRN-URTACHO02-A to Port D of the tachograph.
3. Connect the vehicle’s connector to the other brown connector on HRN-URTACHO02-A.

Second connection — Remote download

The second connection is made to the CAN bus Port C of the tachograph. Only the C5 (CAN-H signal) and C7 pins (CAN-L signal) are used by IOX-UREADER from this port. The CAN bus Port-C of a tachograph is also known as CAN-C, CAN2 or CAN-FMS. Follow these instructions to continue with the installation:

Case 1: Standard connection

Connect the red connector on either the HRN-URTACHO (discontinued) or HRN-URTACHO02-A to Port C of the tachograph.

If Port C is not available, or for alternative tachograph versions that require a different installation process, refer to the other installation cases listed below.

Case 2: VDO tachographs versions 1.2 and lower

1. Before connecting, cut the pink jumper on Connector C (red) of HRN-URTACHO (discontinued) or HRN-URTACHO02-A, between pins C7 and C8.
2. If Port C of the tachograph is already being used, then disconnect that connector and leave it tidied up with the rest of the cables.
3. Connect the red connector of HRN-URTACHO (discontinued) or HRN-URTACHO02-A to Port C of the tachograph.



4. ! IMPORTANT: Do not modify the provided C connector (red). This connection cannot be shared, and there must never be multiple connections as this CAN bus causes interferences in the vehicle CAN bus, which could result in malfunctions.
5. Once connected, switch the vehicle key contact ON and ensure that there are no errors on the vehicle dashboard.
6. Check that all connectors are firmly inserted before placing the tachograph back in its original position.

Case 3: Scania vehicles that had or have an SR6.x tachograph

This is a special case for all Scania vehicles which previously had or currently have a Stoneridge 6.x tachograph. Usually in those installations, tachographs have been or will be replaced with a newer model without modifying the electrical installation.

First, check the connectors A and C. This operation only applies if the vehicle is a Scania with a Stoneridge tachograph with the vehicle CAN bus connected to Port-C of the tachograph. This situation is easy to diagnose as there are no wires connected to A4 and A8. Before connecting the HRN-URTACHO (discontinued) or HRN-URTACHO02-A, make the following modifications as instructed in Stoneridge information bulletin NT2009/012:

1. Remove wires from connector C (red).
2. Remove the C7 and C8 jumpers.
3. Remove the wire in C5 and place it in A4.
4. Remove the wire in C7 and place it in A8.
5. Reconnect connector A (white) to the tachograph and continue with the installation.
6. If you are replacing the tachograph with a more modern one, configure the tachograph as indicated by the manufacturer. If you are not replacing the tachograph, configure the tachograph using a diagnosis tool. Check the following parameters:
7. 1. Ilum.Input (0xFD15): 0 Disabled, 1 CAN, 2 A2. In case of doubt use 0, but do not use option 1.
   2. CAN bus Activ (0xFD1E): 1 Activated.
   3. CAN termination (0xFD5B): Activated if C7 and C8 are jumpered.

Case 4: tachograph Port-C is occupied by the DSRC antenna

Some Stoneridge SRE8.X and EFAS-4.10 have the DSRC antenna connected to Port-C of the tachograph instead of Port-A of the tachograph.

There are different ways to detect if this is the case:

1. Sometimes, there is a T-Harness connected to Port-C of the tachograph. In this case, the T-Harness is connected to the FMS vehicle CAN bus and DSRC antenna. This doesn’t always happen.

1. In all cases, if the current C-Connector (red) is disconnected from Port-C of the tachograph, the tachograph will show this error on screen: Remote detection failure in Stoneridge and DSRC fault in EFAS.

Required changes:

Using the harness HRN-URTACHO (discontinued)

Installation is done in parallel with DSRC wires.

1. Keep the original DSRC antenna connector.
2. Cut the red connector on the HRN-URTACHO (discontinued).
3. Using a T-splice, make the following connections:
4. 1. Connect the HRN-URTACHO (discontinued) yellow wire (CAN-H) to the C5 Connector wire of the DSRC antenna.
   2. Connect the HRN-URTACHO (discontinued) green (CAN-L) wire to the C7 connector wire of the DSRC.
4. Power off the tachograph by unplugging its port A, and then measure the resistance value between the DSRC antenna connector pins C5 and C7 while plugged into the tachograph.
5. 1. If the measured resistor value is around 60Ω, do not cut the bridge wire between pins C7 and C8.
   2. If the measured resistor value is around or below 40Ω, cut the bridge wire between pins C7 and C8, and then protect the cut wires.
5. Reconnect port A of the tachograph to power it back on.

Using the harness HRN-URTACHO02-A

1. Disconnect the vehicle’s connector from the port C of the tachograph.
2. Connect the red connector on HRN-URTACHO02-A to port C of the tachograph.
3. Connect the vehicle’s DSRC antenna connector to the other red connector of HRN-URTACHO02-A.
4. Power off the tachograph by unplugging its port A, and then measure the resistance value between the HRN-URTACHO02-A connector pins C5 and C7 while plugged into the tachograph.
5. 1. If the measured resistor value is around 60Ω, do not cut the bridge wire between pins C7 and C8.
   2. If the measured resistor value is around or below 40Ω, cut the bridge wire between pins C7 and C8, and then protect the cut wires.
5. Reconnect port A of the tachograph to power it back on.

Case 5: VDO tachographs versions 1.3 or greater

For some VDO tachographs you will need additional parts:

1. VDO DTCO Update Card (client supplied)

1. Frontal connection Harness HRN-CL01S2 (C309).

Installation process:

1. Enable Frontal Remote Download with the DTCO Update Card.
2. Connect HRN-CL01S2 (C309) to the VDO Frontal Port.



3. Connect Harness HRN-CL01S2 (C309) to connector D (brown) of the HRN-URTACHO (discontinued) or HRN-URTACHO02-A.

CAN bus clamp installation

The IOX-UREADER allows a connection to the vehicle CAN bus using a capacitive clamp to read vehicle data without electrical contact, thereby preventing vehicle interference and not voiding the manufacturer's warranty. It automatically detects polarity, baud rate, and CAN bus protocol. No configuration is required.

Locate the CAN bus in the vehicle, find the appropriate wires, and then run them through the inside of the CAN clamp as shown below. Hold the wires over the CAN clamp and close it.

✱ NOTE: When planning to install the CAN Clamp on a vehicle for which the GO device has no support, a 3-wire harness (HRN-CW03S3) must be used to install the GO device, otherwise GO device source priorities may not make use of the engine data from IOX-UREADER. If the GO device supports some data and the IOX-UREADER is being used to complement it, then a 3-wire harness is not needed.

✱ NOTE: The position of the wires does not matter, they can be placed in any order and the CAN clamp automatically detects the polarity.

! IMPORTANT: Do not connect the clamp to any wires from the CAN bus CAN-A (pin A4 and A8) of the tachograph, as most of the parameters are not received in this location.

! IMPORTANT: The CAN clamp can be reused by opening it with a screwdriver. Reusing the clamp too many times can damage the clamp and is not recommended.

! IMPORTANT: Never cut, extend or modify the vehicle CAN bus wires.

CAN bus location

Refer to the CAN bus location guide.

Installation with CAN bus clamp

If you are only installing the capacitive clamp and not connecting a tachograph, skip steps 4 and 5 of the Installation Instructions.

You will need these parts:

1. IOX-UREADER kit
2. GO device
3. HRN-CW03S3 (when GO device doesn’t support the vehicle)
