ODSL 30/D… with Serial Output
Transmission formats
The ODSL 30/D… has 2 digital switching outputs and one serial interface which is imple-
mented 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 figure 3.8):
•
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
(Remote Control)
2)
The output format is activated by configuration with the keypad and menu.
Notice!
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 appli-
cation.
1)
Continuous measured value output in a 100ms grid. For the ODSL 30/D 485…, the transfer 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 transfer 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.
