6.3.2 RS232 Port
The development board has an RS232 interface for UART communication. The UART_TXD, UART_RXD,
UART_DSR (GPIO_11), UART_DTR (GPIO_10), UART_CTS (GPIO_8) and UART_RTS (GPIO_9) pins
of the ZE10 are connected with the RS232 port. To enable the RS232 port, the HOST (SW2) switch
should be set to UART.
In addition to the data communication via RS232 port, the RS232 port is capable of supplying power to
the development board. In order to use this feature, supply 5V power via the 9
th
pin of the DB9 socket.
6.3.3 USB Port
The development board also has a USB interface for UART communication. To use the USB port, the
HOST (SW2) switch should be set to USB and the software driver should be installed on the host
computer. The installation CD contains the software.
6.3.4 ZE10 GPIO Interface
The development board’s external GPIO interfaces as well as functional buttons such as factory default
reset switches are internally routed to the ZE10 GPIO pins. Table 6-2 summarizes the development
board’s interfaces and their corresponding GPIO pin numbers of the ZE10.
