TECHNICAL REFERENCE MANUAL
3.2 Output interfaces
The DLS-C(H)/FLS-C(H) contains different interfaces. Measurement results and errors are signaled at the outputs as described below.
RS-232
The RS-232 is meant for the configuration of the device, however measurement can also be taken using the RS-232
interface. Measurement results and/or error codes are sent corresponding to the command description. To use this
interface host system is needed as described in 3.3.1 Controlled mode on page 10.
RS-422
The RS-422 operates like the RS-232, but it is an industrial interface and therefore not only usable for configuration
but also for controlled measurement as described in 3.3.1 Controlled mode on page 10.
The RS-422 can not be used simultaneous with the SSI interface since it uses the same signal lines.
SSI Output
The SSI Interface is only implemented in the FLS type. The SSI interface is updated after each successful measurement
as well as after an error occurs. If the interface is activated, it is updated in all operation modes.
Binary and Gray code as well as error signalization is supported. (See 4.2.6 SSI connection on page 19)
Analog Output
The analog output is updated in controlled and stand-alone mode. It is configurable and works with two ranges:
- 0..20mA
- 4..20mA
Digital Outputs
Three digital outputs are included in the DLS-C(H)/FLS-C(H). Two of them are programmable, while the third is used
to signal an error state of the device. The digital outputs are updated in all operation modes.
3.2.1 Output configuration example
After connecting the DLS-C(H)/FLS-C(H), the following steps are necessary to configure the output behavior.
No. Action Comment Command
1
Set current output range Defines the current output range from 0 to
20mA or from 4 to 20mA.
Example for device 0:
Set current output range from 4mA to 20mA.
s0vm+1<trm>
1)
2
Set distance range Defines the minimum distance (D
min
) and the
maximum distance (D
max
) for the current
range of the analog output.
Example for device 0:
Set distance range from 0m to 10m
s0v+00000000+00100000<trm>
1)
3
Set analog output in case of
an error
Sets the current that should be applied in
case of an error.
Example for device 0:
Set current to 0mA in case of an error.
s0ve+000<trm>

4
Configure digital output Set the ON and OFF level for the digital
outputs.
Example for device 0:
DO 1: off=2000mm on=2005mm
DO 2: off=4000mm on=4005mm
s01+00020000+00020050<trm>

5
Configure SSI Output Activate SSI output (RS-422 is deactivated)
Example for device 0:
Set SSI configuration
Set output value in error case to 12345
s0SSI+1<trm>
1)
s0SSIe+12345<trm>
1)
6
Save settings The changed configuration must be saved to
make it permanent.
Example for device 0:
Save settings for device 0

1) Commands are described in 9 Command set on page 29
Note: If the serial line settings of the device have been lost, please reset the configuration to the factory settings (8 Factory settings on
page 28) using the reset button (6.2 Reset switch on page 24). Please note that the ID switch must be reset manually.
