CD-i Player Serial Cables & Pinouts

*DTR is used as a power supply for some input devices and cannot be used as an active handshake signal.

Cables on this page:

• Serial Printer Cable
• Serial Modem Cable
• Serial Player to Host Cable
• Serial Splitter Cable
• Serial Dummy Plugs

Typical CD-i Player Serial Printer Cable

Player Mini Din-8	Signals	Printer DB-25M
2	RXD <-- TXD	2
3	TXD --> RXD	3
5	GND	7
6	CTS<--RTS	4
7	RTS-->CTS	5,20(DTR)

This cable works if the serial printer is DTE. If this cable doesn't work, try swapping pins 2 and 3 (RXD & TXD), and pins 4 and 5 (RTS & CTS). You can also short RTS & CTS together on the DB-25 side, and skip DTR altogether: it depends on the device.

Typical CD-i Player Serial Modem Cable

Player Mini Din-8	Signal	DB-25M Modem
2	RXD<--TXD	3
3	TXD-->RXD	2
5	GND	7
6	CTS<--RTS	5
7	RTS-->CTS	4,20(DSR)

DUMMY PLUGS

Serial Dummy Plugs: Certain titles may look for the CD-i Player's serial port, and crash if nothing is connected to it. In order to bypass this problem, a dummy plug can be made to fool the application.

• For consumer players(220, 450, 910) take a male mini-Din 8 plug and wire pins 6 and 7 together. Plug the dummy plug into /t2 on the back of the player and run the title.
• For a professional player (602,604,605,615) take a male DB-9 connector and wire pins 7 and 8 together. Plug the dummy plug into port /t3 on the back of the player and run the title.

605 Player Service Shell dummy plug: Their are some diagnostic and other functions available on the 605 through the use of a special plug. You can get to the special "service shell" with the following procedure:

• Wire together pins 2 and 3 on a mini-Din-8 plug.
• Insert the plug into the front mouse port.
• Power cycle the player.
• After the shell comes up, remove the plug and reinsert the mouse.

The service shell is oriented toward the service technician. There are tests for the cd mechanism, serial tests, CD-DA play, etc.

There is also another shell called the Low Level shell. You do not need a special plug, but you will need to connect port /t2 of the 605 to a VT-100 compatible terminal or host running VT-100 emulation using one of the cables listed above. Then, power cycle the player with the space key held down. This shell has diagnostic utilities for DRAM, NVRAM, Slave Processor checks, etc.
