dmm with serial port control
dmm with serial port control
(OP)
I am looking for a handheld dmm with a 232 port
and documented command codes.
There are many out there including the meterman 38xr
but I cannot find any that document the control codes.
They all want to sell some BS software that
could be written in 2hrs by a moderately skilled programmer.
I need to roll some simple software for an automated
data collection project.
Does any know of a meter with documented command codes???
thanks

RE: dmm with serial port control
Those commands are usually very brief. You can easily find out by connecting a scope (memory) to the Tx and Rx lines and analyse the bits as you do some measurements.
Of course, it means that you have to buy that BS SW. But once you have it, it is easy to analyse and you can then write code for any application you want.

RE: dmm with serial port control
But here are two pages:
The first talks "RS-232 cable"

This second one mentions the "isolated optical" cable.(second paragraph/block)

RE: dmm with serial port control
My Fluke has a serial port RS-232 cable that terminates to an IR photodiode optical transciever at the meter end. It is used to download logged or real-time data, not for discrete control. The optical portion provides electrical isolation. Maybe that is what they are referring to?
