2.2 RS232 ON MULTIBUS INSTRUMENT
The RS232 interface on a Multibus instrument can be connected to any RS232 V24 serial (computer) port. Make sure
to respect the hook‐up diagram. Bronkhorst offers special cables for communication, separating the RS232 lines from
the power and analog in‐ and output. On the 9‐pin male D‐sub connector of the instrument RX and TX are available on
pin 6 and pin 1.
RS232 communication is possible by:
 9‐pin Sub D‐connector
(non IP65 applications, e.g. EL‐FLOW)
 8 DIN connector
(IP65 applications, e.g. CORI‐FLOW)
For the exact connections please advise your hook‐up diagram.
2.2.1 Applications, e.g. EL‐FLOW
By default, the interface offers communication at a baud rate of 38400 baud. On instruments that offer
the possibility to change the RS232 baud rate, the baud rate may be configured differently. See the
technical documentation of your instrument which baud rates are supported.
