content: I try create IR to UART to USB converter for DE-5000 LCR meterAny ashttps://www.youtube.com/watch?v=0tOvNqYPlwY&feature=youtu.beI use PL2303HXD USB to UART converter and NPN photo transistor L-53P3C Collector connect to RXD and Emiter to GND.https://www.ebay.com/itm/1PCS-PL2303HXD-PL2303TA-6Pin-USB-to-RS232-TTLCable-Module-for-WIN-XP-WIN7-8-1/172426158988?hash=item282566638c:m:m3I00AwrdnTKYDkCHVGko0AI 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 ashttps://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 usehttps://sites.google.com/site/terminalbpp/9600, 8,1,NoneAny idea, where is the problem?

content: 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.

content: 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.

content: Quote from: ledtester on January 23, 2023, 03:22:53 amInteresting projectThe 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,

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