3.2 Pin Assignment of the RS-232 Interface at a DSUB9 Connector
The names of the signals in the table below are specified as seen from the terminal (here: PC). The
signal direction specified in brackets is shown as seen from the CPCI-ASIO4 board.
For notes on the connection of serial interfaces please refer also to chapter ‘Connection of the Serial
Interfaces to the RJ45-Female Connector’ on page 15. From the principle circuit diagrams
represented in that chapter, you will be able to clearly determine the signal direction (Rx <-> Tx).
