Hi all. I've looked through many topics on the forum about converting TTY to RS232. I need my Arduino Due to talk to an On Screen Display device that uses RS232 serial protocol and takes 12V, so I am looking for a level converter.
It seems like the Max 232 chip is the way to go, but as I search for a breakout board with the Max232 integrated (I'm not great with building boards, I would prefer something I can easily solder to) it's not always clear whether a given board will get me to 12V. Ive seen this issue referred to on the forum a few times, the manufacturers aren't always clear about the voltages in RS232 transceivers.
Can anyone help me understand how to look for something that would work? Again, I'm using an Arduino Due because it can do 3 different serial outs (there will be 3 OSDs for 3 different monitors). This is the OSD chip I'm using is
And this is the Max232 I'm thinking of buying
When I look at the data sheets for these different transceiver boards I get a little overwhelmed and can't figure out what exactly I'm looking for. Any help would be much appreciated.
