'[EE] Interfacing with Chinese RS232 DMMs?'

Hi,

I'm looking for a low-cost data acquisition device. I want to
interface to one of these meters:
 Circuit Specialists MAS-345
http://www.circuitspecialists.com/prod.itml/icOid/4003

The same looking meter is sold by several vendors:
 Mastech MAS-343
 Velleman DVM345DI
 Global Specialties PRO-70. http://www.globalspecialties.com/pro70.html

Similar but different:
 Radio Shack 22-812 (some code at
http://www.kronosrobotics.com/Projects/rsmeter.shtml )
 TekPower TP4000ZC

Anyone have experience interfacing with these? (not using the included
Windows software.)

Regards,
Mark

Replying to myself.  It's been done:
http://search.cpan.org/src/MSCHILLI/Device-MAS345-0.02/MAS345.pm

Is there anything CPAN doesn't have?

Replying to myself again, here is a project in C with some more
documentation on the protocol:

This sounds like a manufacturing test protocol. It speeds up
manufacturing by locating problems faster
in the unit.

Thanks for talking to yourself.
I can use some of this info!

A perl based host program for PICkit 2 similar to your python
based pyk. ;-)

There was a Device::USB libusb wrapper for perl though. So in theory
this can be done. There was a perl based bootloader host program for
PICDEM FS USB demo board.

Device::USB (but personally I think pyusb is better):
http://search.cpan.org/~gwadej/Device-USB-0.21/lib/Device/USB.pm

Perl script for PICDEM FS USB bootloader

http://www.nabble.com/attachment/878980/0/picdem.pl.bz2


Another thing missing for both Python and Perl is the native
HID API wrapper under Windows (you can perhaps add Linux and
Mac OS X here as well).

Did the TP4000ZC output the bit pattern shown on the LCD like the radio
shack meter does?

Yes, it does output LCD segments instead of something sensible.

Similar to the Radio Shack meter, but not compatible.  There's 14 bytes of
data, I think the Radio Shack has 9.

I have the Radio Shack meter too.  They're pretty similar, it wouldn't
surprise me if they were the same chipset with slightly different
strappings.
