Serial connectivity to the Breakout Board can be made in a number of ways. The default configuration of your
development kit will match your expected usage scenario.

Common configurations of the Breakout Board and ISA can be seen in the following figures.
To use the pass-through UART feature of the ISA: plug the larger 12-pin DEI cable into the DEI header on
the Breakout Board and the connector on the ISA. Ensure that jumpers are installed across the 8
10
through. The serial port selection jumpers between the USB and DB-9 connectors should be removed, or
placed on their center pins. Connection to the UART pass-through port can then be made using either of
the two options below:
To use the RS-232 interface: connect a serial cable to the DB-9 connector on the Breakout Board. Ensure
the 4 jumpers above the DB-9 connector are positioned towards the DB-9 connector to send the UART
signals to the RS-232 transceiver, and remove the jumpers from the row of headers next to the DEI port or
make sure the DEI cable is disconnected.
To use the USB interface: install the FTDI USB drivers as described in Section 5.5, “Installing FTDI USB
Drivers”, and connect a USB cable to the Breakout Board and your PC. Ensure the four jumpers above the
DB-9 connector are positioned towards the USB connector to send the UART signals to the FTDI chip, and
remove the jumpers from the row of headers next to the DEI port or make sure the DEI cable is
disconnected.

The V_MOD LED on the Breakout Board will also illuminate to indicate that power is properly applied to
the board and the RCM.

Common Hardware Configurations
Connect to the ISA using InSight Desktop. Launch the console. Choose the Serial 1 tab.
Run a terminal application (for example, Microsoft Telnet Client, HyperTerminal, PuTTY). Connect
to port 4901 on the ISA.
