To use cdilink with your CD-i player you need a so-called CD-i nullmodem
cable. Such a cable used to come with the CD-Interlink disc but you can
easily make one yourself or perhaps borrow one from a fellow CD-i fan.
See the file cables.txt for more information.

The nullmodem cable needs to be connected to the serial port of your
CD-i player. It is typically located at the back of the player and often
marked "Input 2"; for some players you need to use a port splitter cable
on the front port. On consumer players the serial port generally has a
MiniDIN-8 connector; the Philips CD-i 605 authoring player also has
two DB-9 connectors on the back marked "Input 3" and "Input 4".

Here we describe only the cables for a "standard" MiniDIN-8 connector.
More information, including pictures, is probably available on the
Internet. If you have questions or suggestions, feel free to contact me.

* Nullmodem cable for connecting CD-i MiniDIN-8 to PC DB-25

The CD-i side is a MiniDIN-8, male connector.
It looks like this, viewed from the pins:

       2   1

 5       4   3

   8   7   6

The PC side is a DB-25, female connector.
It looks like this, seeing into the holes:

13  12  11  10  9   8   7   6   5   4   3   2   1

  25  24  23  22  21  20  19  18  17  16  15  14

Now, the following pins should be connected:

On the CD-i side                On the PC side

2 (RXD) ----------------------- 2 (RXD)

3 (TXD) ----------------------- 3 (TXD)

5 (GND) ----------------------- 7 (GND)

6 (CTS) ---+               +--- 4 (RTS)
           |               |
7 (RTS) ---+               +--- 5 (CTS)
                           
                           +--- 6 (DSR)
                           |
                           +--- 20 (DTR)
