To create the EIA-232 connection with handshake lines, follow these steps:
1.
If you are connecting your FT 6000 EVB to a development computer for performing
application-level debugging, follow step 1 in the previous section.
2. Verify that jumpers 5-6 (RXUSB) and 9-10 (TXUSB) on JP32 for the USB interface are
disconnected. This is because you can only use one of the EIA-232 and USB interfaces on the FT
6000 EVB at a time. See
Switch, Temperature Sensor, Joystick, and USB Connections (JP32)
earlier in this chapter for more information.
3. Connect jumpers 1-2 (IO8 R10), 3-4 (IO4 R20), and 7-8 (IO10 T1IN) on JP201. This connects
the
IO4
,
IO8
, and
IO10
pins on the FT 6000 Smart Transceiver to the EIA-232 communications
interface on the board.
IO10
is connected to pin 12 on the EIA-232 connector as a serial data
output (TX),
IO8
is connected to pin 14 as a serial data input (RX), and
IO4
is connected to pin 7
as a request to send input (RTS).

4. Connect jumpers 5-6 (IO0 T2IN) on JP203 to route the IO0 signal through the EIA-232 interface
level shifter. This signal is connected to the CTS~ signal on the EIA-232 interface.
You can connect the RTS~ signal from the EIA-232 interface to the IO4 input on the FT 6000
Smart Transceiver using jumper 3-4 on JP201.

In addition, you can connect jumpers 7-8 (FON PD) on JP 203 to prevent the EIA-232 level shifter
from entering sleep mode during idle periods
