IMPORTANT NOTE
ADVARSEL!
Lithiumbatteri -Eksplosionsfare
ved fejlagtig handtering.
Advarsel:
Udskiftning ma kun ske med batteri
af samme fabrikat og type.
Lever <let brugte batteri tilbage ti! leverand0ren.
ADVARSEL!
Lithiumbatteri -Eksplosionsfare.Udskiftning
ma kun
foretages af en sagkyndig,
og som beskrevet i servicemanualen.
Usynlig laserudstraling ved abning nar sikkerhedsafbryderen er ude af
funktion. Undga ud=ttelse for straling.
Bemzerk:
Netafbryderen POWER er sekundzert indkoblet og afbryder ikke
strnmmen fra nettet. Den indbyggede netdel er derfor tilsluttet til lysnettet
sa l.:enge netstikket sidder i stikkontakten.
Observer:
Nettbryteren POWER er sekundert innkoplet. Den innebygdenetdelen er derfor ikke frakoplet
nettet sa lenge apparatet er tilsluttet nettkontakten.

Yarning!
Om apparaten anvands pa annat satt an i denna bruksanvisning specificerats, kann anvandaren
utsattas for osynlig laserstralning, som overskrider gransen for laserklass 1.
Observera!
Strombrytaren POWER ar sekundart kopplad och inte bryter strommen fraan niitet Den
inbyggda natdelen ar darfor ansluten till elnatet sa range stickproppen sitter i \'agguttaget.

Varoitus!
Laitteen
kayttaminen muulla kuin tassa kayttoohjeessa mainitulla tavalla saattaa altistaa
kayttajiin turvallisuusluokan 1 ylittiiviille nakym··attomiille Jasersateilille.
Huom.
Toiminnanvalitsin POWER on kytketty toisiopuolelle, eika se kytke laitetta irti sahkoverkosta.
Sisiianrakennettu verkko-osa on kytkettyna s"hkoverkkoon aina silloin, kun pistoke on
pistorasiassa.
IMPORTANT NOTE FOR USERS IN THE UK
This apparatus is fitted with an approved 13 Amp plug.
To
change a fuse in this type of plug, proceed as follows:
How to connect a plug
J. Remove fuse cover and fuse.
2. Fix new fuse which should be a !3S1362 3/\, A.S.T./\. or 13S1 approved
type.
J. Refit the fuse cover.
If the fitted plug is not suitable for your socket outlets it should be cut off
and an appropriate plug fitted in its place.
If the main plug contains a fuse, this should have a
va lu e of 3A. If a plug
without a fuse
is used, the fuse at the distribution board should not be
greater than 3/\.
NOTE
The severed plug must be destroyed to avoid a possible shock
hazard should
it be insened into a 13A socket.
The wires
in the main kad arc coloured in accordance ,Yith the following
cntle:
blue -'NL'utraP (1N1
): brown -'Lin. ·' ('l.')
J. The blue wire must be connected to the terminal which is marked with
the letter 'N'
or coloured black.
2. The brown wire must be connected to the terminal, which is marked
with the letter 'L'
or col oured red.
J. Do not connect either wi re to the eanh terminal in the plug. which is
marked by the ktter 'E', by the safety eanh symbol. or coloured green or
green and ye ll ow.
l3efore replacing the plug cm·cr. make
cenain that the cord grip i, clamp<?d
over the sheath of the lead -not simply over the two wires.

3.1 Introduction
This chap t er describes some pointing devices, keyboards a nd
modems for a CD-i player.
The mo st important items w ill be discussed for each device:
• Dara rate.
• Data
tlO\Y.
• Data forma t.
3.2 Device Identification
3.2.1 Name convention
For idemification of poiming devices, keyboards a nd modems,
there are on ly rwo signals wh i ch wi ll carry data.
RTS .
--,,
CD-i Input
player Device
RXD . TXD
The first is the RTS signal and is always an ou tput for the CD -i
player. The second is the RXD signal and is always an input for
the CD-i player.
• RXD : carries the data from pointing device, keyboard or
modem to player.
• RTS : is used for device identification.
To identify the input device that is connected to the CD-i player,
each input device w ill transmit its own devi ce ID byte on
reque~t or after power on.
3.2 .2 Device ID sequence
1 :\egate RTS: Current data transmission to the CD-i player is
st opped.
2 Asse rt RTS.
3 The deYice will send i!S 1 by1e device ID.
4 Sending a comple te data packet is recommended after the
identification
b~1e to determine the state of the buttons at
Sta rt - up .
NOTE
-The CDi-keyboard sends i !S 1 byte device ID , and clears its
buffer.
-Data tran~mis~ion to the CD -i player can cont inue. The
10
first byte
se nt to the CD-i player shou ld be the h eader byte of
the device data packet (the fi rst by1e of a data packet d7 = 1).
