1.4 Short form start-up
All necessary settings for this module are already performed at Bronkhorst.
To follow next steps carefully is the quickest way to get this module operational in your own Modbus environment.
Instruments with combined RS232 / RS485 signal lines and no user interface automatically detect the
bus type at start-up.
Warning: this device uses a vendor specific pin layout on the RJ45 connector that differs from the
Modbus recommended pin layout.

switches on the instrument. Also you can use the FLOWFIX program to change Slave
address and baud rate via the RS232 connection (it may be needed to restart the
instrument to apply the changes). Slave address and baud rate can also be changed
using the button (if present) on the instrument.
