DE-5000 IR to USB communication kit?

[Carpenter]

I try create IR to UART to USB converter for DE-5000 LCR meter
Any as
https://www.youtube.com/watch?v=0tOvNqYPlwY&feature=youtu.be



I use PL2303HXD USB to UART converter and NPN photo transistor L-53P3C Collector connect to RXD and Emiter to GND.

I thing if Transmit IR LED in DE-5000 shines is NPN Shitch ON and ground RXD.

I was expecting if I on DE-5000 press PC I in PC recieve any as https://www.eevblog.com/forum/testgear/decoding-der-ee-lcr-meter-de-5000-serial-bitstream/
 unfortunately I recieve only <0>  or 00 in hex view mode every 1sec.
In PC I use  https://sites.google.com/site/terminalbpp/
9600, 8,1,None

Any idea, where is the problem?

In case anyone is still interested in building a custom IR-to-UART adapter...
I very recently created my own little blog where I offer everything needed in order to build your own adapter:
https://tltb.slur97.org/ir-to-usb-adapter-for-der-ee-de-5000-lcr-meter/
That includes the 3D models, a schematic and sourcecode - all free of charge, of course.

Hi ThomasLE,

I'm getting a 502 bad gateway, is the website down?

[thomasLE]

Oh damn it - I didn't see your message until now
The website should be working again now.
Cheers!

This is perfect. I recently picked one of these up and I have used a sparkfun breakout rs232 style board and a sensor to recive the data. I found some Python script but it doesnt work currently so I was toying with getting that working. Of course I got distracted becuase a 3d printer turned up and I was just thinking about making a model for the sensor. This saves me a few hours.

I guess the only thing to do now is print it all up and get it working. I wonder if the unit can take input, I know its go no sensor for receiving signals but it looks like they had planned to do it just never did it.

Interesting project 

The schematic shows U1B (unused 1/2 LM358) with the output grounded, this will cause excessive current draw in U1.
Should leave this output open instead of grounded as shown.

Best,

I've just built this but without the op amp and just reused the IR housing. Works great, thanks @thomasLE.
