Interface

6.1 Digital Output RS232

For digital communication, the standardized RS 232-Interface (V24) is used in duplex mode.
After startup the sensor transmits the angle values in degrees (°) continuously.

Electrical Levels

RS232:
PARAMETER
V High-level output voltage
OH
V Low-level output voltage
OL
I High-level input current
IH
I Low-level input current
IL
(‡)
I Short-circuit output current
OS

(†) TA = 25°C.
(‡) Short-circuit durations should be controlled to prevent exceeding the device absolute power-dissipation ratings, and no more
than one output
