Connector Specification

Data D-SUB9 Connector (P2)

Pin Number Signal Description
1 DCD NC
2 RXD Receive Data
3 TXD Transmit Data
4 DTR NC
5 GND System Ground(Signal Ground)
6 DSR NC
7 RTS Request To Send
8 CTS Clear To Send
9 RI NC
  • WIZ750SR-110 supports only 4 signals. (TXD, RXD, CTS, RTS)
  • If you want to use all 9 signals, you have to make them separately. or you must design new hardware
  • TXD, RXD, CTS, RTS are provided as peripheral functions.
  • And already made DSR and DTR signal in GPIO functions.(WIZ750SR Firmware code)
  • Therefore, DCD and RI functions must be created.
  • RXD, TXD, GND: These are all you need if the device does not use hardware handshaking.
  • RXD, TXD, GND, RTS, CTS: These are the signals used when serial device uses hardware handshaking.
  • DTR, DSR: Not used
