The DE2-115 board uses the ZT3232 transceiver chip and a 9-pin DB9 connector for RS-232
communications. For detailed information on how to use the transceiver, please refer to the
datasheet, which is available on the manufacturer‟s website, or in the DE2_115_datasheets\RS-232
folder on the DE2-115 System CD.
