Serial port (IOIO) Connector Pinout (232/SA/SAP versions only)
The XRTx’s serial port connector is configured to look like a standard 9-pin “DCE” serial port. Therefore, in
most applications a straight through serial cable or adapter-plug (DB9-Female-to-Male) is used to connect
an external serial device (for example, a PC) to the XRTx transmitter.
The DB9-F serial port is only available on XRTx-232, -SA and –SAP models.
