Description
Set this parameter to HART multiplexer.
Set this parameter to the COM port your
RS485–RS232 converter or your RS485–USB converter
is connected to (see chapter 4.4).
Set the baudrate according to the settings of the
Gateway's baud rate. The Gateway's baud rate can be
adjusted via the DIP switches inside the Gateway housing
(see chapter 6.1) or via software (see chapter 5.5.3, see
chapter 5.5.4).
Depending on the RS485–RS232 converter used, it may
be necessary to switch on or off the request-to-send
control in order to be able to switch over correctly between
reception and transmitting mode
Specify if you want the Gateway to be the primary or the
secondary master. If, for example, there already is a
primary master connected, you have to choose
Secondary master.
Number of preambles for HART communication.
The number of retries for HART communication in case of
an error.
