Hi,

i have bought a Ophir 20C-UAU laser measure head with USB-Plug.
I can use this with a windows PC, but i dont have a windowsPC on my garage.

I use linux, Arduino, Raspberry .. but no WIndows ;-)

any ideas or experience how to connect the Ophit 20C-UAU with a Raspberry or a Arduino ?

Greetings

Probably, though I'm not familiar with this specific head. I imagine it shows up as a serial device, so you could probably plug it in, find out what device name it's using and connect to it with Putty or something else that'll read data from a serial device to get the readings ... That's my guess anyway.

I'd think so. If you connect it to your windows pc, can you see additional serial ports appearing in the device manager?

If you do, it probably uses an on-board usb to serial chipset, and you may be able to find linux drivers for that. At that point you'd be able to communicate with it and get raw data out, but i'm not sure how to translate that data into measurement results. This is probably done in (windows) software and you'd need to replicate that functionality to make the measurements make sense.

You're one of those rare linux users that doesn't dual-boot? :D If you can afford a $1,045 power meter, I think you can afford a $5 windows XP CD... or at least an old $40 windows laptop ;) That would be easier and faster than trying to port the software to a different OS.

You could also tap into the analog signals directly if you have some basic electronic skills.

yes .. no dual boot ... why ? pffffff ;)
on a raspberry dual boot ? sounds funny :yh:

the problem with the Ophir USB is, that after connectig the device shows a Serial 00000000
The FTDI driver does not work with this, but by arduino pro mini works fine...

the Ophir uses other drivers than the normal FTDI ... but the controller on the Ophir board is a FTDI.

my idea is .... get the Tx/RX Signal from the Chip and connect with a µC.

i hope for a better solution

Greetings


the sensor was sold as "used", but unopened at ebay from a seller. the price ... i do not say ;-)
