Thank you for reading;
I made an inline logic level to RS232 level translator with a MAX232
sandwiched between two RJ45 sockets (jacks?). It is great for communicating
with MCU via a PC using phone line cables and plugs. It looks like a phone
line coupler and is powered by the MCU. But, it is not easy to make. I was
hoping that such a device is available to buy. Or, a kit or artwork for a
circuit board is available.
Thanks
