Tx header
A header for the received data is defined at the output via the

for the data output.
The input is restricted to two characters and must be entered via the context menu or the
button. It is possible to enter control characters and constants. The input field is high-
lighted in red if invalid characters are entered.

Tx terminator
A terminator for the received data is defined at the output via the
parameter.

for the data output.
The input is restricted to two characters and must be entered via the context menu or the
button. It is possible to enter control characters and constants. The input field is high-
lighted in red if invalid characters are entered.
5.8.8.2
Auxiliary input/Auxiliary read result
This option can be used if you intend for data from an external device such as a hand-held
scanner to be output
instead of
the specific sensor reading. The auxiliary input must be
made when the sensor's reading gate is closed.
The external device data is entered in the sensor's database and output immediately at
all
configured interfaces
– including the fieldbus interfaces – in the same way as a specific rea-
ding result.
This generates
the same format
as is used in the case of a specific result. The data is inter-
preted by the sensor and can also control the digital outputs and, if necessary, the beeper.
The data can also be checked using
evaluation conditions
(e.g., at Match 1).
5.8.8.2.1
Rx header
The
parameter is used to define a
header for the received data
. This header is
used by the sensor to identify the start of the input data. The identification must differ from
the SOPAS command. It is recommended to use the default setting.
The header is restricted to two characters and must be entered via the context menu or the
button. It is possible to enter control characters and constants. The input field is high-
lighted in red if invalid characters are entered.
5.8.8.2.2
Rx terminator
The
parameter is used to define a
terminator for the received data
. This ter-
minator is used by the sensor to identify the end of the input data.
The input is restricted to two characters and must be entered via the context menu or the
button. It is possible to enter control characters and constants. The input field is high-
lighted in red if invalid characters are entered.
5.8.8.2.3
Bar code type
parameter determines which bar code type is used to enter the received
data in the sensor. The selected bar code type must also be enabled in the sensor.
For the U

FIRST
CHARACTER
FOR
IDENTIFICATION
setting, the first character after the
must correspond to the code ID for the required bar code.
