Using the diagnostic port
RBRcervello Antarctica and dual-modem
The RBRcervello diagnostic port consists of a six-pin bulkhead connector with power and RS-232 connections. It is meant to be used in conjunction with an RBR patch cable with RS-232 electrical connections, like the one provided in the RBRcervello Antarctica shipping crate.

Use a terminal emulator to communicate with the RBRcervello through its diagnostic/debug port.
Windows
On a Windows-based workstation, use any terminal emulator console that supports a serial port, such as Tera Term.
Tera Term
Tera Term is an open-source terminal emulator that lets you connect to hosts via serial port or the network. The default settings should work with the RBRcervello interface. In the unlikely event when they do not, load the configuration file provided below using the "Setup→Restore setup" menu.

Alternatively, configure the settings manually as follows:
.
In "Setup→Terminal setup" menu, enter the terminal size:
In "Setup→Keyboard setup" menu, select "Delete key":
.
.
In "Setup→Serial port setup and connection" menu, select the correct COM port:

.
.
Highlighting text on the terminal automatically copies it to the clipboard. Right-clicking on the terminal will paste the saved text on it.
Linux
On a Linux-based workstation, use any terminal emulator console that supports a serial port, such as Minicom.
Minicom
Minicom is a serial communication program that connects to devices through a GNU/Linux serial ports. Use the "-s" command to set up the terminal with the right port and settings, or execute it with explicit settings at runtime with the correct device:
minicom -b 115200 -D /dev/ttyUSB0

To copy and paste text from and to a Linux terminal, use Ctrl+Shift+C and Ctrl+Shift+V.
Diagnostic menu overview
Access the RBRcervello menu via the diagnostic port using an RS-232 interface (115200 8N1). It is a fully-featured Bash terminal (Restricted Bash) with "tab" completion. To see the list of available commands, execute the "help" command. You will find all you need to deploy the RBRcervello with the RBR instruments. As a quick in-menu reference, each command displays a short manual when executed with the "-h" or "--help" argument.
