Initialization
If an ETK type supported by the ES592.1 is connected to the ETK interface it is
recognized automatically. The ETK interface is automatically initialized.
If an ETK type which is not supported by the ES592.1 is connected to the ETK
interface the overall system behaves, as if no ETK is connected. No specific
error message is generated.
5.6.2
Operating Modes
In addition to single transfer for application with the ETK, the ES592.1 supports
data transfer in block mode. The ES592.1 module usually works in block mode;
single mode is supported for compatibility reasons.
The following table lists the features of the individual operating modes for the
ETK interface.
“Basic” Operating Mode
When using the “Basic” operating mode, older projects are supported without
any change. All ETK interface hardware can be used.
“Compatibility” Operating Mode
An important feature of the “Compatibility” operating mode is block transfer.
The block transfer between the ETK and the ES592.1 is activated automatically.
This means the following advantages:
• Extended number of variables per measure rate
• Considerably faster download times for code and data to the ECU
• Considerably improved transfer times for rapid prototyping rates
“Advanced” Mode
The “Advanced” operating mode provides a number of other possibilities.
The 100
Mbit/s Block ETK protocol results in increased ETK interface perfor

mance. The most important advantages in comparison to the “Compatibility”
operating mode are:
• 16 rates for measuring
• possibility to configure the number of variables per measure rate
