Help with Personal labview project

[ZInventor]

First off, i want to make sure readers understand, this is not a team project.


I'm working on making a program to pull data from a USB Geiger-Mueller counter that i was given.

the programing specs are as folows:

[QUOTE user="black cat sysems"]Interfacing a GM-10 / GM-45 Radiation Detector

Writing your own software to take readings from a GM-10 or GM-45 is very easy. The RS-232 versions are self powered off of the DTR and TX Data lines of the serial port. Open the serial port (usually the handshake lines are correctly asserted automatically by the computer) at 57,600 baud, 8 data bits, one stop bit.

Each time a particle is detected, a pulse is sent down the serial line, which is interpreted by the serial port in the computer as byte. So if you count the number of bytes received per minute, you have the Counts Per Minute (CPM). Likewise you can count the number of bytes over any time period you wish. The value of the byte received is not defined, just count the bytes.

The USB version of the GM-10 and GM-45 are also self powered. Drivers for MacOS, Mac OS X, and Windows are provided to make it emulate a standard serial port, so the software interface is the same. Visit our Linux Details page for specific Linux information. [/quote]

i've gotten labview to get the first byte of data, but the system seems to stop running after that (the geiger counter turns off)

I'm wondering if anyone could help:

what i need is a program that displays the CPM (counts per minute) and a continuous counter (with reset)

i'm frustrated as to how to get this to work.

i've attached what i have so far.

if anyone has any ideas, please tell me!

thanks so much
