Technical Support DSGW-210

Referring to the DSGW-210 SDK quick start guide section 3 Target Setup. Can you confirm that the connection points (TP1100 and TP1101) for a serial connection are underneath the board (not as shown in the diagram)?

Please check it on your board, it should have some information on it (marked TP1100/TP1101), it is located underneath the board.

Thankyou - I found TP1100 and TP1101 underneath the board. Where should I use for a ground connection?

Can I confirm that the connection is 3.3V?

you need to power with 5V，and using USB-c port

I have connected power via the USB-C and the unit boots.

I need to connect to the serial connection. Your document says that I should use TP1100 and TP1101 for the serial connection. My questions are;

  1. where should I make a ground connection?
  2. is the serial connection 3.3V or 5V?

Thanks!

  1. The ground pin is TP1102.
  2. You do not need 3.3v or 5v for serial connection. Only those 3 pins.

Thank you for your response.

Regarding 3.3V or 5V. Can you confirm that the logic level is 3.3V?

Thanks
Allan

I believe is 5v, but do not input USB-c power if you use 5v port

10

The logic level is 3.3V.

Dusun is it possible to pick up the serial port on the other side of the PCB. This location is problematic as it means leaving the top off and disconnects all the lid mounted antennas.
