When wired correctly it works great!
The media could not be loaded. So, I used this TTL to connect my scale with a RS232 output. Then connected to Arduino Nano for the logic functions of reading the scale info and then only printing the weight value from the scale in numeric and barcode format. It’s a dedicated solution I was targeting for and succeeded. After finalizing the code and electronic connections I then 3d printed a case to enclose all components. Turned out really nice. The printer uses the hardware serial rx and rx while the scale uses software serial1 for the scale rx and rx.

Swap rxd and txd
Great product for the money. Mine were all RS3232 chips and output correct voltage. Unfortunately, the pin labled txd is actually rxd and rxd is txd. A lame mistake by the maufacturer but once you know, they work well. Using this for serial testing with a LibreComputer "Le Potato" connected to pins 4,6,8,10 which map to /dev/ttyAML6 once you "ldto enable uarta". I would buy more but this came with 5x units. All set for four more projects.

Easy to use, BUT beware of VCC in
First, all of these worked so no complaints there. Contrary to what I'm reading here, RX and TX silkscreens are NOT labeled backwards. But the spec on a DS232 I.C. REQUIRES +5V for VCC. These chips are not designed to operate at 3.3V. If your circuit needs a 3.3V TTL level from/to this device, use an open collector component, such as 2N4401 or 7406 with 1K pullup resistor to level shift the 5V TTL down to 3.3V

Nice TTL to RS232 converter
I was using this to convert the TTL from the Arduino to the RS232 of my Stone HMI display. Then I got brave and removed the 4 SMT resistors on the Display and re-soldered them on the TTL line. Now I don't need these, but they were very good for testing functionality before doing surface mount soldering...

They work!
I use these in my PIC projects.

Worked well.
Hooked TX to TX and Rx to Rx. Worked fine with an USB to rs232 adaptor on the other end.

MAX232 RS232 based com port connection for your projects
These allow connections to RS232 lines and convert to TTL level signals, all units work as advertised

easy to use.
Great price for this product. I would not be able to purchase the parts to make this myself for the price!!!
