3.3.2 Parameters
The following sections describe the various parameters. After changing
parameter(s), click the ‘Save to Board’ button and wait a while until the
new value(s) are accepted by the board.
3.3.2.1 Communication
The Communication box refers to card’s communication port – either
serial or USB. The current Port and Baud Rate are shown. They are ‘read
only’, that is, not changeable. (About changing the Baud Rate for a serial
port, refer to section 3.3.1.2.) A third item (‘Get results immediately’) is a
parameter controlling card’s response in communication during the Fill
mode.
3.3.2.1.1 Port
Shows port’s type and number, e.g., “USB port COM4” or
“SCI port COM1” (SCI stands for ‘Serial Communications Interface”, that
is, RS232 or RS485).
3.3.2.1.2 Baud Rate
Specifies the actual Baud Rate in which the Settings utility is
communicating with the card. Refer also to section 3.3.1.2.
3.3.2.1.3 RS485 Address
Up to 64 LCIC-WIM boards may reside on one RS485 bus consuming
only one PC port. In case you do not need this feature, specify RS485
Address = 0; this will simplify the coding of your application. If you do
like to utilize this feature, specify the required RS485 Address – between 1
to 64.

The address setting takes effect only upon board reset.
