Parameters
5.8.8
Serial input data
The
tab contains the parameters for handling input data. The following
options are available for handling input data from the serial aux and host interfaces:
• D
ATA
FORWARDING
• A
UXILIARY
INPUT
• EDS
TEXT
ELEMENT
IN
OUTPUT
FORMAT
The data can be transferred to the sensor via the serial aux/serial host interfaces.
The telegram identifier must differentiate between STX and ETX SOPAS commands, as other
SOPAS commands can be sent to the sensor. It is recommended to use the default values
for headers (
) and terminators (
) for the received data.
5.8.8.1
Data forwarding
This option can be used if you intend to send data from an external device such as a hand-
held scanner to a host
in addition to
the reading result. In this case, the data is not inter-
preted by the sensor, but is also output at the specified interface. The digital outputs are
not controlled
and the data is not processed according to evaluation conditions.
Possible destinations are:
• Serial aux interface
• Serial host interface
• Ethernet aux interface
• Ethernet host interface
5.8.8.1.1
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.
5.8.8.1.2
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.
5.8.8.1.3
Target interface
The
parameter determines which interface is used to
output the data
.
The following sensor interfaces can be used as a data output for data forwarding:
• Serial aux interface
• Serial host interface
• Ethernet aux interface
• Ethernet host interface
