Linux SoM
DPI is an USB to 3V3 TTL serial interface designed to get the access to the Acme boards debug port.
DPI replaces the old FOXCONS interface and enable to access the board debug port using a simple USB port instead of an obsolete RS232 port not always available on the modern PC.
DPI is based on the popular FTDI FT232 chip. The relative driver is almost ever already installed on any PC either Window or Linux. If not get it from http://www.ftdichip.com.
To use the DPI you need a terminal emulator program that is an utility that can send and receive characters via a serial port.
By default Windows provide an utility called HyperTerminal that is usable with DPI 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.
At startup you have to specify:
Save this configuration and press the Open button to continue.
You will receive a request of login end password. Use these credentials:
Aria G25 or Terra board:
Login: root Password: ariag25 |
FOX Board G20:
Login: root Password: netusg20 |
A simple terminal emulator available on Linux is minicom.
On Ubuntu distribution you can install it using Synaptic or apt-get install by typing:
~$ apt-get install minicom
After installation run it by typing:
~$ minicom
Type CTRL-A followed by O to show the configuration panel. Then select Serial port setup and access to the serial port configuration.
Se the port as shown below:
Welcome to minicom 2.4

Welding a 5 pin strip (not included) and using the little cable provided with the LCD as shown below it is possible to use the DPI to program a 4DSystems serial display.
 | DPI is an USB-to-serial interface to link the Acme boards debug port to a PC USB host port and have access at the Linux system console using a terminal emulator program like minicom, putty, hyperterminal, etc. | More info... | |
