Continental HNA11_00 Telematics Control Unit Instruction Manual

HNA11_00 Telematics Control Unit
Instruction Manual

INTRODUCTION

The Telematics Control Unit (TCU) described herein is a vehicle-mounted Telematics control unit designed and manufactured by Continental for exlusive use by a premium automotive OEM. The product name has been designated by the customer as RAMSES (Router And Mobile SErviceS). The TCU contains an embedded LTE wireless communication module and interacts with remote call/data centers to provide valuable services to the vehicle customer.

PURPOSE AND SCOPE

This conditions document is to provide installation instructions to OEM to ensure safe use of the device.

TCU FUNCTIONALITY

The RAMSES TCU provides LTE advanced connectivity to the vehicle and interfaces to the vehicle head unit as well as the Ethernet bus. The TCU is designed to

• initiate automatic emergency calls if an automatic emergency call trigger is received;
• allow initiation of a Manual Emergency Call by a car occupant;
• allow manual initiation of Roadside Assistance or Information Calls by a car occupant;
• establish Data Packet Connection with telematics service;
• establish Data Packet Connection to support the internet connection of Head Units equipped with WiFi (Head Unit is not Continental’s product).

ELECTRICAL HARDWARE DESCRIPTION

POWER & GROUNDING

The power supply subsystem for the Ramses TCU conditions unfiltered fused vehicle battery input and distributes the necessarily regulated voltages required for each of the subsystems and circuits in the design.
Vehicle battery nominal is defined as:
Nominal 13.5V (The operating voltage range as UBmin=6V, UBmax=16V)

TCU INTERFACE TO EXTERNAL RF SIGNALS

These connectors provide the coaxial connections for RF signals for LTE and GPS connectivity to antennas. They are populated as needed for each variant technology.

AUDIO SUBSYSTEM

The Ramses TCU audio system will provide a hands-free user interface for emergency Telematics calling within a vehicular environment. The user interface is realized through the seamless connection between the Ramses TCU module and the vehicle.
At a glance, Ramses audio system shall provide the following interfaces.

• Microphone front end input with switchable bias
• Amplified speaker driver via class D amplifier
• Speaker load diagnostics and protection via PA I2C
• Support for digital audio IO via HDBaseT
• Hands-free processing and prompt playback realized by the SOC

LABELING

TCU labeling complies with the regulatory homologation compliance mark(s) that are required by law in the country.

VEHICLE INSTALLATION GUIDELINES

Normal operating conditions are between -40°C to +80°C.

The sheet metal cover is designed to be a heat sink. A gap between the heat sink and the mounting surface is recommended to facilitate heat transfer out of the module. Exceptions can be made if the module is mounted to a surface that can help facilitate heat transfer such as a large aluminum body panel.
WARNING: When the temperature of the device is above 70oC, the metal cover will be hot. DO NOT TOUCH.
The device does not have sealed connectors. It is designed to meet Class I water intrusion conditions (no drip test required), so it should not be placed in area that can get wet. Continental recommends that the automotive OEM uses the mating harness supplier’s recommendations for the keep-out zone around the connectors to ensure proper mating of each connector.
Changes or modifications to this system other than a facility authorized by Continental could void authorization to use this equipment.

REGULATORY COMPLIANCE NOTES

FCC:
This device complies with Part 15, Part 22(H), Part 24(E), and Part 27 of the FCC Rules. The device contains FCC ID LHJ-WT50NA02. Operation is subject to the following two conditions:

1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired operation.

FCC Part 15B Statement:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

INDUSTRY OF CANADA:
This device complies with Industry Canada’s license-exempt RSS. Operation is subject to the following two conditions:

1. This device may not cause interference; and
2. This device must accept any interference, including interference that may cause undesired operation of the device.”

This device contains a radio transmitter with IC ID 2807E-WT50NA02 that has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

EXTERNAL ANTENNA REQUIREMENTS FOR USE WITH HNA11_00 TCU

The HNA11_00 device is for use with external antennas ONLY.

This radio transmitter (FCC ID: LHJ-WT50NA02; IC: 2807E-WT50NA02) has been approved by FCC and Industry Canada to operate with the antenna types listed below with
the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

INSTRUCTIONS TO OEMs

The OEM must inform the end-user (i.e. the owner/driver of the car with this device installed) that “The installation of HNA11_00 with its radio transmitters and antennas is in compliance with the U.S. and CANADA RF Exposure Regulations”. This text, or similar, must be included in the car manual.

Antenna Information:
Only the same or equivalent-type antennas as shown below have been evaluated and may be used with this module. Other un-equivalent-type antennas may require additional authorization for operation. The equivalent type means the same antenna type that results in similar in-band and out-of-band radiation patterns.

For incorporation in the Vehicle platform (the distance from the antenna to the user according to OEM installation requirements):

Antenna Placement:
This device is authorized for installation in qualified vehicles that can provide enough minimum separation distance. To ensure RF exposure compliance the antenna(s) used with this module must be installed in vehicles to provide a minimum separation distance, in all operating modes and orientations of the vehicles. The separation distance is measured from the antenna and the passengers in all directions for potential exposure conditions. This module must not be co-located with any other RF modules or transmitters.  Additional SAR evaluation and FCC equipment approval would be required if other RF modules or transmitters are co-located with this module. The required minimum separation distance for the antenna placement is 10.25 mm.
