Hello everyone. After manually assembling the firmware, I received a non-working device. I connected to the router via the DT-5001A USB to RS232 adapter, but the console shows incomprehensible symbols. If anyone has encountered this, please help.
The device responds with indicators to the connection of the lan and wan ports. The rx tx gnd signal wires are connected correctly. I even tried swapping rx tx, but the console shows nothing at all. VCC +3.2V from the native power supply. I checked GND, it rings on the usb port.
Всем привет. После ручной сборки прошивки , я получил не рабочее устройство . Через DT-5001A USB to RS232 adapter я подключился к роутеру , но в консоли у меня не понятные символы. Кто сталкивался помогите пожалуйста.
Устройство реагирует индикаторами на подключение lan и wan порта. Сигнальные провода rx tx gnd подключил верно . Пробовал даже менять местами rx tx , но в консоли вообще ничего не показывает. VCC +3,2V с родного блока питания. GND проверил , он звонится на usb порт.
R362 у меня находится в другой части платы , потому что 3 ревизия
Stop trying with that adapter, it will (or already has) damage the router permanently. You adapater is not operating at 3.3V, it's a standard RS-232C adapter which may use up to 25 volts (more likely 15 volts), which is way too much for the router, which operates at 3.3V.
You will need to get yourself a usb2serial adapter operating at 3.3V and connected gnd, rx, tx - NOT Vcc/ 3.3V and power the router by its own power supply. If you can't get a 3.3V based usb2serial adapter, you could also do the the old fashioned way with a level shifter (max232?) to get your signals down to 3.3V signal levels, possible, but not recommended. Chances are that this DT-5001A has already damaged the router permanently.
