1.5.1 Identifications on the Product
The following symbols are used for identifications of the product:
CAUTION
The ETK can be damaged or destroyed!
Some components of the ETK board may be damaged or destroyed by electro-
static discharges. Please keep the ETK in its storage package until it is installed.
The board should only be taken from its package, configured, and installed at a
workplace that is protected against static discharge.
CAUTION

CAUTION
Risk of short circuiting the internal signals of the ETK!
When you mount the ETK to the ECU, you must ensure that the screws and
washers used will not penetrate the ETK printed circuit board.
CAUTION
Differences in case ground potentials can cause high currents to flow
through the shields of the cables that connect various system modules.
Ensure that the module mounting surfaces are at the same electrical potential or
insulate the modules from their mounting surfaces.

3.1 Architecture
Fig. 3-1 shows the block diagram of the BR_XETK-S4.0.
Fig. 3-1BR_XETK-S4.0 Architecture
While the microcontroller accesses the program data (not the program code) out
of the data emulation memory provided by the microcontroller, the content of the
data emulation memory can simultaneously be modified by the calibration and
development system through the Automotive Ethernet interface. This process
enables adjustments of parameters, characteristic lines and maps through the
calibration and development system. Using an additional measurement data mem-
ory area, the ECU microcontroller can provide data to the calibration and develop-
ment system by buffering the data (DISTAB17) and triggering the BR_XETK-S4.0 to
read the data via SWD. The BR_XETK-S4.0 then reads, buffers, processes and
sends this measured data to the PC.
If no additional measurement data memory is available, the BR_XETK-S4.0 can
alternatively read the data to be measured directly from the microcontroller’s
memory. This process is Triggered Direct Measurement (TDM) with DISTAB17.

ETAS BR_XETK-S4.0 | User Guide
The 100 Mbit/s XETK Ethernet interface provides communication with the PC.
3.2 ECU Interface
The BR_XETK-S4.0 is connected via connector CON2 to the ECU with an adapter
cable (refer to Fig. 3-2 on page 17). The pin definition depends on the application
and the microcontroller type. In general, the ECU interface consists of
- 1 ECU voltage line, which is not used for XETK power supply, but only for
detection of the ECU status, therefore the power consumption on this line is
negligible (refer to chapter 3.4 on page 19)
- 1 Reset line which allows the XETK to control and monitor the system reset
of the ECU
- 1 Reset line which allows the XETK to control and monitor the power-on
reset of the ECU
- 5 Debug lines for the communication between the BR_XETK-S4.0 and the
microcontroller
- 5 ground lines for proper shielding of the ECU interface lines.

3.3 Automotive Ethernet Interface
The Automotive Ethernet interface (100BASE-T1) of the BR_XETK-S4.0 can not be
connected to a PC directly, but a media converter has to be inserted in between.
Its purpose is to transform the physical layers of Automotive Ethernet (1 differen-
tial pair / 2 wires) into Standard Ethernet (2 differential pairs/ 4 wires) and vice-
versa. The media converter has to be connected to CON1 (refer to Fig. 3-4).
The combination of the BR_XETK-S4.0 and the Automotive Ethernet media con-
verter CBEB10x.1 / ES16x.1 or an ES882.1 / ES886.x ECU Interface Module is inte-
grated in the ETAS IP world with automatic IP management and supports the open
automotive "Universal Measurement and Calibration" standard "XCP on Ethernet"
(TCP/IP, UDP/IP).
The open "XCP on Ethernet" interface allows for connecting to the BR_XETK-S4.0
with third party application software.
NOTE
The Automotive Ethernet interface is not compatible with the standard Ethernet
interfaces of ETAS modules. A CBEB10x.1 Media Converter or an ES88x ECU Inter-
face Module is needed to connect the BR_XETK-S4.0 to the PC.
NOTE
Please see chapter 6.1.2 on page 39 for additional information regarding PC
requirements for the Ethernet interface.
CAUTION
See chapter “Requirements for failsafe Automotive Ethernet Operation” on
page 30 for details on wiring the Automotive Ethernet interface cables.

3.4 Power Supply
The BR_XETK-S4.0 requires a permanent power supply. It is typically powered
directly from the car battery. The input voltage may vary (see chapter 6.6
on page 43). In case of higher input voltages to the XETK, additional voltage pro-
tection is required. The BR_XETK-S4.0 will also accept voltage dips down to 3 V (for
additional details of low voltage operation, see ISO standard 16750).
From the input battery voltage, switch-mode power supplies provide all necessary
voltages on the BR_XETK-S4.0. The power supply of the ECU is not affected by the
BR_XETK-S4.0. An automatic switch ensures, that the power consumption of the
BR_XETK-S4.0 is reduced to a minimum, when the XETK enters its standby (sleep)
mode.
The BR_XETK-S4.0 is supplied with power through the connector CON3.

3.5 Status LEDs
There are three LEDs displaying the operating status of the BR_XETK-S4.0
(Fig. 3-6 on page 20).

LED State Definition
Red On BR_XETK-S4.0 is supplied with power and active (i.e. the ECU
is switched on or the ETAS calibration and development sys-
tem is connected and ready to communicate with the BR_X-
ETK-S4.0)
Green Off Working Page contains data and is accessible from INCA
Flashing BR_XETK-S4.0 is in boot configuration mode:
- measurement and calibration are not possible,
- BR_XETK-S4.0 update with HSP is required
On Power supply has dropped under selected threshold:
- data retention of the calibration data manager in the ECU is
no longer ensured
- as soon as the BR_XETK-S4.0 switches on again, the ECU
switches to the Reference Page.
Green LED stays lit until the calibration and development sys-
tem downloads data into the calibration data memory. Other-
wise switching to the Working Page is not possible.
