3. Hardware Setup using a RS232 Serial Adapter
Connect a target board to a PC running the Silicon Laboratories IDE via the RS232 Serial Adapter (EC2) as shown
in Figure 2.
1. Connect one end of a RS232 serial cable to a Serial (COM) Port on the PC.
2. Connect the other end of the RS232 serial cable to the DB-9 connector on the RS232 Serial Adapter.
3. Connect one end of the 10-pin ribbon cable to the RS232 Serial Adapter’s DEBUG header.
4. Connect the other end of the ribbon cable to the target board at the DEBUG or JTAG connector.
5. Connect a ac/dc power adapter to the power jack on the target board.
Notes:
• Use the
Reset
button in the IDE to reset the target when connected using an RS232 Serial Adapter.
• Remove power from the target board and the RS232 Serial Adapter before connecting or disconnecting the
ribbon cable from the target board. Connecting or disconnecting the cable when the devices have power can
damage the device and/or the RS232 Serial Adapter.
• A RS232 Serial Cable is necessary when using the RS232 Serial Adapter. Serial cables are not included
with the purchase of the RS232 Serial Adapter.
