I've got one of these, also came to me new in the box but that was around
twelve years ago and other than a short period of testing has stayed there
ever since, nothing wrong with it as far as I can remember just too much
stuff, too much to do, and Thunderbolts and the like do take up a bit less
How long do you have before you need to make a decision?, I can let you
have a copy of the software if you want to play with that first, and the
manual too if you don't have ongoing access to it at the moment.
Interestingly, the Proteus software is badged Symmetricom, although I
don't recall anything to suggest that they and Parthus had any working
My manual indicates the software as suitable for Win95, Win98, and NT,
which does rather show its age:-), but I've run it ok on a P4 WinXP machine
using a standard RS232 port.
I could try an installation under Win7 via a USB to serial adapter but my
Proteus is tucked away in its box so I would need a bit of time to get it
set up, and whilst that obviously won't confirm it will work with Win 10 it
might at least be a step nearer.
Unfortunately whilst the manual does give information on the message format
for the time port output it doesn't for the control port, just refers to
the supplied CDU software.
Presumably it could be sniffed at the port but the manual does state that
the messages are binary format and that a terminal emulator can't be used
The Proteus was supplied in 12, 24, and 48 Volt versions, and this will be
indicated on the label on the unit. One thing to be aware of, just in case
it doesn't come with original antenna, is that the antenna port feeds 12
Volts DC to the antenna, rather than 5 Volts, or even 3.3 Volts, as often
found later. As far as I remember this isn't made clear in the manual.
Week 1024 rollover is discussed in the manual and shouldn't have been an
issue, at least that's what they said for the 1999 rollover:-), but again I
can check that if you don't need to make a decision in the next day or so.
I have the chance to buy a new boxed unit. Having glanced at the manual I
understand that the configuration software runs under Windows 95 and uses a
serial RS232 port. The only Windows box I have now runs Windows 10 and has
USB only. So my questions are, can I run the config software under Windows
10 and will a USB to serial adaptor work with it? I will need to make a
power supply for it as I think it requires 24 volts. That should be no
Any comments great fully received.
Thanks in advance,
