Permanent programming of a DigiSnap 2000 Series controller requires a computer with a serial port or a USB-to-serial converter cable. Many computers (laptops, especially) don't have serial ports and will require a USB-to-serial converter. Finding a reliable USB-to-serial converter can be difficult, so we now offer a high-quality USB-to-serial converter cable as an optional accessory to DigiSnap 2000 Series products. This cable is based on the FTDI chipset, which we have found to be much more reliable than the other popular chipsets. Current drivers and installation guides for our cable can be found on FTDI's website: http://www.ftdichip.com/Drivers/VCP.htm. Once you have the USB-to-serial converter drivers installed, you will be able to use a terminal emulator program to communicate with the DigiSnap 2000 Series controller. To find a terminal emulator program for your operating system, read the corresponding section below:
Application and guide: DigiSnapTerminalGuide.zip
Minicom is a robust, mature terminal emulator for Linux.
Install minicom with your distribution's package manager. On Ubuntu, the commnd is "sudo apt-get install minicom". The Ubuntu community documentation has instructions for using minicom: https://help.ubuntu.com/community/Minicom.
The settings required for communicating with the DigiSnap are 19200 bps 8N1. The command to start minicom with these settings is "minicom -b 19200 -o -D /dev/ttyUSB0" where /dev/ttyUSB0 is the name of your serial port. The default name for the first USB-to-serial converter on Linux is /dev/ttyUSB0. If your computer has a real serial port, it is probably named /dev/ttyS0.
