1.3 Block Diagram
The following block diagram shows how the ES1222.2-A board
works.
Fig. 1-2 Block Diagram
Both the communication controller and the MPC555 microproces-
sor have their own bus system. The two bus systems are connected
via a buffer.
The VME64x interface contains the buffers for data and address
lines as well as the interrupt logic.
The two dual-ported RAMs can be accessed both from the VMEbus
and the communication controller.
The communication controller makes four CAN interfaces available
as well as the K-Line and L-Line interfaces. Their signals are routed
to the connectors on the front panel via dc decoupling.

This chapter contains a detailed functional description, information
on hardware configuration and the connectors, and the technical
data of the ES1222.2-A board.
2.1 Functional Description
This section gives you a detailed overview of the features of the
ES1222.2-A board. You will find information on the following sub-
jects:
•interfaces
•CANbus data acquisition
•analog output
•Ipetronik modules
•updating the firmware
•connectors
2.1.1 Interfaces
The ES1222.2-A board has four CANbus interfaces and a serial K-
Line and L-Line interface for connecting VMEbus systems with
external devices.
It also has a communication controller for data exchange via the
serial interfaces. This guarantees high data transfer rates.
Serial CANbus Interface
The ES1222.2-A board has four CANbus interfaces. The CANbus
signals are routed to four 8-pin connectors, CAN1 to CAN4, on the
front panel. The connection to the external device has a maximum
transfer rate of 1 MBit/s (ISO high-speed). The following CAN proto-
cols are supported:
•CAN protocol V2.0a standard identifier (11 bit identifier)
•CAN protocol V2.0b extended identifier (29 bit identifier)
•KWP2000 on CAN
The four CANbus interfaces support the ASAP1a protocol to
guarantee ECU calibration, and the acquisition and monitoring of
CANbus communication data in the vehicle bus.
If you use the ES1222.2-A board for ECU calibration via the CANbus
channels, the ASAP1a protocol has to be implemented in the ECU.

10 Hardware
Serial Diagnostic Interface
There is a 14-pin K-Line connector on the front panel of the
ES1222.2-A board for connecting the K-Line and L-Line of the ECU
diagnostic interface. The system’s control software determines the
functionality of the K-Line interface of the ES1222.2-A board.
The transfer rate can be a maximum of 250 Bit/s. The transfer rate
and system frequency are set using the control software. The inter-
face supports the following calibration and diagnostic protocols:
•McMess
•Keyword71
•KWP2000
If you use the ES1222.2-A board for ECU calibration with the K-Line,
certain protocols have to be implemented in the ECU:
VME64x Interface
The board has a VME64x interface. The system controller identifies
and configures the address ranges and interrupts once the VMEbus
system has been switched on.
The board can be configured for AutoSlot detection in accordance
with the VME64x specification or the ETAS specification.

2.1.2 CANbus Data Acquisition
The ES1222.2-A board makes flexible recording and acquisition of
communication data possible, which is exchanged between ECUs in
a CAN network.
Data from up to four individual CAN busses can be acquired and
recorded. If CANbus data is acquired using interfaces such as the
KWP2000 or CCP, the data is acquired synchronously to the ECU
data. The number and configuration possibilities of the CAN bus
and its messages are prescribed by the relevant control software.
By configuring with jumpers JP1-JP3, you can connect two CAN
buses in parallel on the ES1222.2-A board. For more information on
the configuration of jumpers JP1-JP3, please refer to the section
"Jumpers JP1-JP3" on page 13.
2.1.3 Analog Output
The ES1222.2-A board has an analog output voltage on the K-Line
connector for programming ECUs. The output voltage varies
between 3 V and 24 V with a resolution of 12 bits.
2.1.4 Ipetronik Modules
The Ipetronik modules have a CANbus interface. The various
Ipetronik modules can be connected in series and connected to the
ES1000 using a CANbus of the ES1222.2-A board.
The following modules are supported:
•SIM_VIN (voltage measurement - 8 channels)
•SIM_SENS (voltage measurement with sensor supply - 8
channels)
•SIM_DMS (strain gauge - 8 channels)
•SIM_CNT (universal counter - 4 channels)
•SIM_Thermo (thermocouple temperature measurement -
8 channels)
note
For more details on the support of Ipetronik modules, please consult
the ETAS product catalog or contact ETAS directly.

2.2 Firmware Update
The firmware of the ES1222.2-A CAN + K-Line board can be
updated using a service software running on the connected PC
while the board is mounted in the ES1000 system.
2.2.1 Connectors
There are four connectors on the front panel for CANbus-signal
transmission and one connector for the K-Line and L-Line. The four
connectors, CAN1-CAN4, are 8-pin Lemo sockets. There is also a
14-pin K-Line connector available (also a socket) for the signals of
the K-Line and L-Line.
2.3 Hardware Configuration
The following sections contain information on the configuration of
the hardware using jumpers.
