6.5 Analog output
The analog output of the DLS-C(H)/FLS-C(H) is a current source (0..20mA or 4..20mA). It is capable of driving loads up to 500 Ω.

The stated errors include all possible errors as Temperature drift, linearity, surface color and measurement distance.
The best accuracy of ±1.5 mm for the DLS-C(H) 15 and ±1 mm for the FLS-C(H) 10 can only be
achieved by using the digital interfaces (RS-232, RS-422 or SSI)
6.6 RS-232 serial interfaces
The RS-232 interface is used for device configuration. It is made to connect the sensor to a PC to do the configuration either by terminal
program or by the UtilitySW (See 3.1 Connection for configuration on page 8).
If the Moving Target measurement characteristic is active, a measurement speed of 250Hz is only
possible if the baud rate is set to 115200. Lower baud rates reduce the measurement speed
6.7 RS-422 serial interface
The RS-422 interface is made for industrial communication and therefore long cables (twisted pair) are supported. This interface is thought
to use the DLS-C(H)/FLS-C(H) in controlled mode.
The RS-422 interface cannot be used simultaneous with the SSI interface.
If the Moving Target measurement characteristic is active, a measurement speed of 250Hz is only
possible if the baud rate is set to 115200. Lower baud rates reduce the measurement speed
