Debug Serial Port Interface --- CORE9G25
Feature Hardware ref Linux Tutorials Debian Tutorials pinout

RS232 Debug module is an DB9 RS232 to 3V3 TTL serial interface designed to get the access to the CoreWind boards debug port.


RS232 Debug Module is based on the popular MAX3232 chip. only change the TTL level to RS232 level, then you can connect it bwteen the board and the PC with the serial cable.

To use the RS232 Debug module you need a terminal emulator program that is an utility that can send and receive characters via a serial port.

Connect the Debug serial port on CORE9G25-CON board

Connect the Debug serial adapter to the J7(DEBUG) Port with 10Pin cable, then connect the DB9 to PC serial port.

Serial terminal emulator on Windows PC

By default Windows provide an utility called HyperTerminal that is usable with RS232 Debug module but we suggest to install a free utility called putty because it can works also as a SSH remote terminal useful to have access to the FOX command prompt via LAN (read this article).

It doesn't need to be installed, just download and run it, if you can't download it, you can find it in our CD.

At startup you have to specify:

  • Connection type: Serial
  • Serial line: COMx where x is the serial port allocated by the ftdi device driver
  • Speed: 115200

Save this configuration and press the Open button to continue.
