3.4.3 ODSL 30/D… with serial output
Transmission formats
The ODSL 30/D… has 2 digital switching outputs and one serial interface which is implemented either as
an RS 232 interface or as an RS 485/RS 422 interface. The transmission rate can be set to between
600 and 115200 baud.
The serial transmission is carried out with 1 start bit, 8 data bits and 1 or 2 stop bits without parity.
For the transmission of the measurement values, 6 different transmission modes may be configured (see
• ASCII measurement value (6 bytes, measurement range 0 … 65m, resolution 1mm)
1)
• ASCII measurement value 0.1mm (7 bytes, measurement range 0 … 65m, resolution 0.1mm)
1)
• 14 bit measurement value (2 bytes, measurement range 0 … 16m, resolution 1mm)
1)
• 16 bit measurement value (3 bytes, measurement range 0 … 65m, resolution 1mm)
1)
• 20 bit measurement value (4 bytes, measurement range 0 … 65m, resolution 0.1mm)
1)
• Remote control operation
2)
The output format is activated by configuration with the membrane keyboard and menu.
1) Continuous measurement value output in a 100ms grid. For the ODSL 30/D 485…, the data transmission is carried out in
RS 422 mode, i.e., with permanent transmission on the Tx+ and Tx- lines.
2) For the ODSL 30/D 485…, the data transmission is carried out in RS 485 mode, i.e., the Tx+ and Tx- lines are switched to
receive. This permits several ODSL 30/D 485… to be connected onto a single bus. In this case, the device addresses of the
individual devices must differ from each other.
The ODSL 30/D 232… can also be operated via remote control, however, only as a point-to-point-connection between the
ODSL 30 and the controller.
NOTE
Selecting an output resolution of 0.1mm does not change the internal measurement system of
the ODSL 30 and does not increase its accuracy. For this reason, measurement values with a
resolution of 0.1mm may vary in successive measurements depending on the application.
