[Question]How to select RS232 or TTL ?

jhpark · 发表于 2023-5-16 10:55:07

I'm tryng to communicate my DMG10600T101_A5WTR with RS232 or TTL(high priority),
but I couldn't find any pin or switch to select in my of board.
Does DMG10600T101_A5WTR change it automatically without any user configuration ?

I guess the default is RS232 (as usual in other boards),
then connect T2, R2 and GND to my USB2RS232(PL2303TA) as below picture :

Serial port 2 is at RS232 level, that's right. Try downloading attachments with an SD card and testing serial communication again

Thanks for answer, but I'm not sure whether I did well and it's work or not.
Because I saw nothing updated..

I'm using this setting with SSCOM.

You did not download it. The SD card needs to be formatted. Follow the screenshot below to proceed

At this time, I have a little change at my updating screen.
Is this correct ?

I connected it as like :

screen T2 - tx pc
screen R2 - rx pc
screen G - gnd pc

and, of course I tried as below too :

screen T2 - rx pc
screen R2 - tx pc
screen G - gnd pc

Which connection is correct ? I guess 2nd one is correct in normal case.

and do I have to connect the vcc too ? maybe 3.3v or 5v..

Dear, DMG10600T101_A5WTR this screen is powered by 7-36V, RX2/TX2 should be cross wired.

Thanks for confirmation !
Then, for now, there is no fault in my setting but no response yet..

Does DMG10600T101_A5WTR support TTL too ? How to change to use TTL instead of RS232 ?

DMG10600T101_A5WTR support RS232

The following examples can be used to change the 232 level to TTL level：【教学视频】T5L 去掉232芯片短接为TTL
