Version 4 and 5 (32 bits)
The DRIVERS\WIN32 sub-directory contains the following files:
rh0232.VBP
rh0232.BAS
rh0232.FRM
Labview
The routines described here were tested using Labview for Windows 95 version 4.0.
While it is possible to access all of the driver routines described earlier, it is easier to use the special Labview access routine.
The rh02.llb library in the
DRIVERS\WIN32
sub-directory shows how to access this routine.
To use this routine, copy rh02
.llb
and rh0232.dll to your labview user.lib directory.
You the rh02 sub-vi will now appear in the user libraries box. You can load the rh02_example sub-vi which demonstrate how
to use it. The sub-vi accepts the port (1 for COM1) and, optionally, whether to filter the data. It returns the temperature in
degrees Celsius and the relative humidity in percent.
HP-Vee
The example program rh02.vee is in the drivers\win32 directory. It was tested using HP-Vee version 5 under Windows 95.
The example shows how to collect readings continuously from the rh02.
Serial port settings
The following table shows the standard serial port settings for COM ports.
Port
Base address
Interrupt
Standard
COM1
3F8
4
Yes
COM2
2F8
3
Yes
COM3
3E8
4
de facto
COM4
2E8
3
de facto
COM5...
No
Note that, on most computers, it is not possible to use the same interrupt for two serial Ports at the same
time. If, for example, you wish to use COM1 and COM3 at the same time, it is necessary to use a serial port
card which can be set to an interrupt other than 4. These can be obtained either from Pico Technology or
your computer supplier.
