Contents Introduction
Pin-out schemes
This page gives an overview of the pin-out schemes for the connectors on the ISDN Link.
Pin-out RS-232 COM Port
Pin Signal name Direction2
1 Carrier detect, CD From DCE
2 Receive data, RXD From DCE
3 Transmit data, TXD To DCE
4 Data terminal ready, DTR From DCE
5 Signal GND
6 Data set ready, DSR From DCE
7 Ready to send, RTS To DCE
8 Clear to send, CTS From DCE
9 Ring indicator, RI From DCE
1) Only RXD, TXD and signal GND are used, the
other pins are reserved for possible future use.
2) The ISDN Link is the DCE (Data Circuit-
terminating Equipment).
