I'm learn how to use the Optocoupler with RS232 Data. I have a working unit Scanner, but want to Isolate it from the I/O pin once the Data has been received. I've Googled and YouTubed what I could to figure it out. But has anyone ever done this before and got it working?
I'm using my DG4062 (SQ Wave) & Scope for my test signal for now and a BOE.
I've used this (on hand) part before as a switch (https://www.mouser.com/ProductDetail/Broadcom-Avago/ASSR-1411-001E?qs=/ha2pyFadujqZRlk8FbaCxsFnFMaIZhm0pCj%2bakKD4xmiRcEDqqyeg==
), will it couple Data?. Inverter Amp. arrives tomorrow.
Find attached the 2 designs I think may work. One is from the Sparkfun.com website.

Thanks for any help.
