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
Installation.
To use the device remotely, you need to log on to start, and log off when
finished. When logged on, FlowCERT LITE will show ‘Remote ON’ on
the display, and “Communicator OFF” when logged off.
All commands should be followed by a carriage return.
The unit will respond either OK (or a value) if the command is accepted, or
NO if it is not.
To log on, send the command
/ACCESS:pppp where pppp is the passcode (P922).
To log off, send the command
/ACCESS:OFF
To read a parameter value, send the command
/Pxxx where xxx is the parameter you wish to read, and the FlowCERT
LITE will respond with the parameter value.
To set a parameter, send the command
/Pxxx:yy where xxx is the parameter number, and yy is the value you wish
to set it to.
