IEEE 754 floating point example

Note :
Use direct-echo RS232 adaptor for instance performance.
Also, refer to the IEEE floating point (single and double precision) specification section.

You can send or receive IEEE 754 floating point value by choosing 'float' or 'double' type in [FX] category field in serial protocol configuration dialog.

The '4-byte float' button sends 's0' and expects to receive 'r0' which is same with 's0' in protocol configuration. To emulate this 'echo' situation, it would be better to use direct-echo RS232 adaptor. If the deployed applet or application does not receive 'r0', the gauges will not be updated.

The '8-byte double' button sends 's1' and expects to receive 'r1' which is same with 's1' in protocol configuration. To emulate this 'echo' situation, it would be better to use direct-echo RS232 adaptor. If the deployed applet or application does not receive 'r1', the gauges will not be updated.
