Hi everyone,
I have a setup consisting of 4 USB interfaces powered by an old Notebook 12v PSU feeding six power cords (4 for the interfaces and 2 for the scanners). Then connected up the 4 USB connections into a cheap ($4 on ebay) 4 port USB hub into my old IBM Pentium PC running XP SP3.
The two scanners have two discriminator leads from the one tap - in parallel. No impedance matching or protection.
This setup allows me to monitor two POCSAG frequencies with two baud rates each (512 and 1200) - 4 streams.
I have 4 instances of PDW, configured them to match the ports, running on old IBM Pentium PC running XP SP3!
The system runs 24x7.
The problem I have (and I don't know whether it's PDW or an Windows OS issue) is that at every few days at seemingly random and variable times, any one of the PDW windows freezes - no meter movement, no decoding. All other PDWs continue normally. Lights are flashing on the data converter. It's only been one window at a time (although that could be just because of the frequency of failure and two haven't yet failed at the same time).
I've worked around this by forcing a daily automatic reboot to reset the applications, but that doesn't prevent the freeze - just makes sure they are all restarted and working once a day.
Anyone experiencing the same issue, or have any thoughts?
Cheers
...Steve
