RS-232C Serial I/O Interface
The board contains a DB9 connector (J29), which provides a bidirectional
RS-232C serial I/O interface. The board contains the transceiver (U41),
however the logic controller (UART) must be implemented in the
Stratix II device. Table 34 describes the device used to implement the
RS-232C interface.
J29 is a standard DB-9 serial connector. This connector is typically used
for communication with a host computer using a standard 9-pin serial
cable connected to (for example) a COM port. Level-shifting buffers (U52
and U58) are used between J29 and the Stratix II device, because the
Stratix II device cannot interface to RS-232 voltage levels directly.
J29 is able to transmit all RS-232 signals. The Stratix II design may use
only the signals it needs, such as J29’s RXD and TXD. LEDs are connected
to the RXD and TXD signals, giving a visual indication when data is being
transmitted or received. Figure 9 shows the pin connections between the
serial connector and the Stratix II device.
