Hi,

I am referring to this document. However when I write “:wu1000”, the 200220 device is not registering the voltage to be 10V.

 

Also in the serial monitor, when I send the command :wu1000 I just receive back the ascii value of each character.

Hello Omar Ahmad，

Did you set a output voltage that higher than input?

Here are some comment by Mitchel. It may help you.

Hi,

I usually use the 200310 and I have no issue with communication UART.

Using the same method, I can’t get anything from the 200220.

What is the address of the 200220 for UART communication?

How do I set the address?

Is there any instruction available?

Thank you for your help.

Hi,

I just bought the DC-DC bulk converter (model 180078/180080) from your amazon store.
I would kindly ask about the pintout of the serial port and also if the protocol mentioned in this chat (for model 200220) works also for my model.

 

Thanks,

Alexis Nicole

The seagulls were eyeing my food. I played chicken road with one hand. Slots are easy to play. I hit a lucky spin and won a decent amount. I bought an extra portion of chips just to feed the seagulls (don’t tell anyone). A fun afternoon by the sea with a little gambling win on the side. Brighton is always full of surprises and good vibes.</span>

Hey, understanding communication protocols and correctly configuring serial ports is essential for the operation and control of specialized electronic equipment. A friend suggested spin granny casino with solid rewards in Greece and my win on Sweet Bonanza was the perfect way to unwind after a long day of technical testing and adjustments. It really made my night and proved that choosing a stable and reliable platform always pays off.
