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) and 7-8 (IO10 T1IN) on JP201. This connects the 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 as a serial data output (TX) on the EIA-232 interface, and IO8 is
connected to pin 14 as a serial data input (RX).
4. Run Windows HyperTerminal or another terminal emulation program on your computer to
monitor the serial output. Configure your terminal emulation program for direct connection to
your serial port using the serial parameters specified in the device application. See Configuring a
Device Application for Serial Debugging earlier in this chapter for more information on
configuring your device application for application-level debugging.
Note: You can use only one of the EIA-232 or USB interfaces on the FT 5000 EVB at a time.
For information on implementing serial I/O, see the EIA-232C Serial Interfacing with the Neuron Chip
engineering bulletin (005-0008-01D).
Connecting the EIA-232 Interface (with handshake lines)
You can enable the EIA-232 interface with handshake lines to connect your FT 5000 EVB to a
development computer for performing application-level debugging or to connect it to other
microcontrollers.
To create the EIA-232 connection with handshake lines, follow these steps:
1. If you are connecting your FT 5000 EVB to a development computer for performing
application-level debugging, follow step 1 in the previous section.
