22 FT 5000 EVB Hardware Details
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
5000 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 5000 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 5000
Smart Transceiver using jumper 3-4 on JP201.
5. 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. See Connecting the ShortStack Interface later in
this chapter for the locations of these jumpers.
