Following this period of time, the actual program starts. If configured accordingly (also
refer to Figure 21 on page 38), the transmission coils will be automatically tuned. This
procedure takes another 16 seconds.

4.2.3.1
Serial (RS 422)
The serial output may be configured in various ways. The transmission rate is adjust-
able at 19200 or 38400 Bd, the output protocol may be chosen as either „transparent“
or „3964R“. Apart from that, the content of the output telegrams is configurable. From
a parameter list the required parameters may be selected.
4.2.3.1.1
List of the system data which can be output
One Telegram consists of max. 21 user bytes. The minimum update rate at 38400 Bd
is then calculated as follows:

Formula: Minimum update rate
As the transmission is binary, it is possible to add further (DLE) characters to the pro-
cedure when using the 3964R-procedure.
All multiple-byte variables are output either with the highest byte or the lowest byte first
(adjustable)!
The 8 bit check sum is only output when using the transparent protocol and includes
the start pulse. The start pulse, as well as the check sum (protocol transparent), can-
not be removed from the data block.
