Description
DCD = Data Carrier Detect
(this is an input to the DB9-USB-RS232-F from
the application DCD output)
RXD = Receive Data
(this is an input to the DB9-USB-RS232-F from
the application Tx output, normally labelled RXD
in DCE convention)
TXD = Transmit Data
(this is an output to the DB9-USB-RS232-F from
the application Rx input, normally labelled TXD in
DCE convention)
DTR = Data Terminal Ready
(this is an output to the DB9-USB-RS232-F from
the application DSR input, normally labelled DTR
in DCE convention)
GND = RS232 signal ground
DSR = Data Set Ready
(this is an input to the DB9-USB-RS232-F from
the application DTR output, normally labelled DSR
in DCE convention)
RTS = Request To Send
(this is an output to the DB9-USB-RS232-F from
the application CTS input, normally labelled RTS
in DCE convention)
CTS = Clear To Send
(this is an input to the DB9-USB-RS232-F from
the application RTS output, normally labelled CTS
in DCE convention)
