5.1 The Serial Interface of the VSP/VCP
The transducer is equipped with a serial RS485 interface. To set the device ad-
dress for communication via RS485 please remove the rubber cap over the ad-
dress switch (1) and then set the address switch to a value between 1 and 16 using
a small screw driver or similar tool (2). Afterwards insert the rubber cap again.
Communication telegrams are transmitted as ASCII text according to the Thyra-
cont protocol version V2. Detailed information is provided in the separate descrip-
tion »Thyracont Communication Protocol«.

Interface Parameter:
9.6 / 14.4 / 19.2 / 38.4 / 57.6 / 115.2 kBd, 8 databits, 1 stopbit, no parity
When powered on the transducer starts with 9.6 kBd. If a telegram
with different baud rate is received, the transducer will automatical-
ly adapt to it. For this automatic baud rate adaption a maximum of
two telegrams of type »Type Query« or »Measurement Query« is
required.
The analog output signal 0-10 V is simultaneously available with
the RS485.
