The E3 PIEP SCI to RS232 Serial Board converts TTL level serial communications signals to RS232 compliant signals. The board implements full flow control (CTS and RTS) and is suitable for both 3.3V and 5V operation. Additionally, driver chip remote shutdown and transmit are implemented and controlled through corresponding SPIP pins. Remote shutdown, remote enable, CTS and RTS features can be disabled by removing / cutting the associated jumpers (freeing the corresponding SPIP resources for use by stacked peripherals). The JST interface connector contains all implemented RS232 signal lines (CTS, RTS, TX, RX) as well as power and ground, enabling the interface connector to control and power RS232 accessory devices. For additional information, refer to SP3222E data sheet.
