Using the RS232 Serial Interface
The RS232 serial interface is used to communicate between the FlowCERT
LITE
and a PC using the optional Ultra PC and other associated Pulsar
software packages, to obtain information such as data logging and view echo
traces upload, download and save parameter files. In addition it can also be
used to control or obtain information using a standard PC or other computer
base equipment. To do so, the settings for control are as follows:
baud rate
19,200 , 8 data bits , no parity , 1 stop bit .
The device should be connected, via the serial port, as shown in Chapter 2
