4.1 Overview
The complexity of the automotive electronics systems steadily increases with
the rising number, growing range of functions and networking of ECUs and
electronic components in motor vehicles.
Serial communication buses such as the CAN bus (Controller Area Network)
play a dominant role in the exchange of data in networked systems . In addition
to CAN buses, vehicles with other bus types are equipped for networking com-
ponents which are connected to networks via gateways.
The ES922.1 CAN FD Module (2 Channels) is an extension module for the
ES910.3-A Rapid Prototyping Module. Together with the ES910.3-A, the
ES922.1 module is part of an efficient, compact development and experiment
platform with high processing and simulation power.
It uses a target-oriented and rapid floating point processor. The RTA-OSEK
operating system of the ES910.3-A, which is compatible with the AUTOSAR,
ensures a smooth transition from finished functional prototypes to ECU soft-
ware development.

5.2 CAN interfaces
CAN FD (CAN Flexible Data Rate) is an improved, downward compatible CAN
protocol. It differs from CAN mainly in the expansion of the payload per mes-
sage from 8 to 64 bytes, higher data rates of up to 8 Mbit/s and longer check-
sums, which increase the reliability of transmission. CAN FD covers the
demand for a higher bandwidth for networks in the automotive industry. At the
same time, CAN FD nodes can easily be integrated into the existing CAN infra-
structure.
An 8-pin plug connector on the front panel is assigned to each of the two CAN
interfaces of the ES922.1 module (CAN1 and CAN2 LEMO sockets). The CAN
interfaces are galvanically isolated from one another.
5.2.1 Operating modes
The CAN interfaces of ES922.1 can be configured and operated independently
of one another in the High-Speed CAN (CAN FD and CAN) and Low-Speed CAN
operating modes. The ES922.1 module supports both ISO-compliant and non-
ISO-compliant CAN FD.
The operating mode is selected in the application software and in the web inter-
face of the ES910.3-A (see chapter 6.3 on page 25).

5.2.2 Timestamp
The ES922.1 time stamps the CAN messages. The INCA application software
synchronizes the measurement data captured by the ES922.1 module with sig-
nals from other ECUs and measuring modules with high precision.
5.2.3 Feature
The CAN applications supported by the ES922.1 are listed in an overview in
chapter 7.9.2 on page 32.
5.2.4 Bus terminating resistor
Low-Speed CAN
Two relatively high-value terminating resistors of 2.26 kilo-ohms each (RTH,
RTL) are integrated in the ES922.1 module for the Low-Speed CAN connection.
This dimensioning ensures that the ES922.1 does not significantly affect the
sum of terminations of the overall system in an already terminated CAN net-
work. An inspection should always be carried out, however, especially for labo-
ratory networks or when running tests in existing networks.
In a Low-Speed CAN network, the individual nodes are typically terminated with
between 500 ohms and 6 kilo-ohms. For optimal system conditions, the CAN
network should be completed with approximately 100 ohms (parallel connec-
tion of all terminations).
Detailed information about the Low-Speed CAN network can be found in ISO/
DIS 11898 "Road vehicles – Controller area network (CAN) – Part 3: Low-Speed,
fault-tolerant, medium dependent interface".
CAN FD and High-Speed CAN
The CAN FD and High-Speed operating modes of the CAN interface require the
use of bus terminating resistors.
According to the CAN specification, one bus terminating resistor of 120 ohms
is required at each of the two open ends of the bus. The terminations must be
connected to the cable or the plug.
Some CAN networks are already terminated (for example in a vehicle), so no
additional termination is required.
NOTE
The bus terminating resistors provided for the High-Speed CAN operating
mode cannot be used for this operating mode.
NOTE
ETAS offers cables and terminating resistors of 120 ohms to set up CAN net-
works.

5.3 Functions "Wake-Up"and "Sleep"
The ES922.1 module supplements the "Wake-Up" function of the ES910.3-A
module by additional control options. The ES922.1 can switch on the entire
ES910.3-A/ ES922.1 system in the vehicle in a controlled process.
The entire ES910.3-A/ ES922.1 system is generally in one of three different
states: Off, standby and on.
Fig. 5-2Operating modes
Detailed information about the operating modes can be found in the ES910.3-A
manual.
5.3.1 "Wake-Up" function
The "Wake-Up" condition is satisfied as soon as signal transmission is present
on at least one of the CAN buses for the ES922.1 module.
5.3.2 "Sleep" function
The "Sleep" condition is satisfied as soon as signal transmission is no longer
present on the CAN buses.
5.3.3 Configuration
The "Wake-Up" and "Sleep" behavior of the ES922.1 is configured in the web
interface of the ES910.3-A module (see chapter 6.3 on page 25).
NOTE
The ON/AUTO switch of the ES910.3-A must be in the AUTO position in order
to use this function.
NOTE
The "Wake-Up" function is only supported if at least one CAN interface of the
ES922.1 is configured as CAN FD or High-Speed CAN.

5.4 Firmware
5.4.1 Firmware for the ES910.3-A and ES922.1 modules
The necessary firmware is also loaded when the extension module is plugged
in and the firmware for ES910.3-A is updated with the ETAS "Hardware service
pack" software (HSP). Updating the firmware update is imperative in the follow-
ing circumstances:
• After installing an extension module for the first time
• After changing the type of module in the extension slot (e.g. swapping
ES920 for ES922.1).
If different copies of the same module type (e.g. ES922.1) are used in direct
succession in the same module ES910.3-A, no further firmware update is
required.
5.4.2 Firmware update
The firmware of the ES922.1 can be updated by the user so that future versions
of the module can also be used. The firmware update is carried out using the
HSP service software on the connected PC.
NOTE
As delivered, the ES910.3-A module does not contain any firmware that sup-
ports the modules that can be mounted in the extension slot.
NOTE
The connection to the PC and the power supply to the ES910.3-A must not be
broken while the firmware is being updated.
