Nokia phone can support three protocols of transmission over cable:
-
-
-
-
M2BUS (called often simply MBUS) - 9600,N,...
-
FBUS - 115200
-
AT mode - 19600
-
-
-
You cable can support each of them...and phone must be compatible with it
-(for example, CAN'T use DLR-3 with phone, which show "headset connected"
-after connecting it)...
-
-
Schematics
-
-
-
Simple M2BUS (only) cable:
-
-
Note:
-
-
-
74HC04 must be in HC version
-
Dioda Zenera 3,2 V it required for phones different than 21xx, 3110
-
-
-
FBUS cable:
-
-
-
Switch for M2BUS/FBUS for cable above:
-
-
-
Cable for AT mode is unavailable here, because it needs programmed chip
-and I don't know, what programm should be inside...
-
-
To make FBUS/MBUS cable you have to connect:
-
-
-
FBUS - GND, TX and RX
-
M2BUS - MBUS and GND
-
-
-
Phone connectors

What are original cables for Nokia phones ?
-
-
-
-
-
DAU-3 (or DAU-3H) - cable for Nokia series 2100.
-Sell with Nokia Cellularware (it isn't produced now).
-
-
-
-DAU-4S - cable for Nokia 3110 and all models in series 8100 (8110, 8110i, 8148 and 8148i).
-Sell with Nokia Cellularware (it isn't produced now).
-
-
-
-DAU-4F - uniwersal (FBUS/M2BUS) cable without switch,
-for Nokia 3110 and all models in series 8100 (8110, 8110i, 8148 and 8148i).
-Sell with Nokia Cellular Data Suite 1.0 (it isn't produced now).
-
-
-
-DAU-9P - uniwersal (FBUS/M2BUS) cable without switch, for Nokia 51x0/61x0.
-Sell with Nokia Cellular Data Suite 1.2 - 3.0a.
-
-
-
-DLR-1 - cable sell with Nokia 9000 Communicator. It can be used
-to exchange date between phone and computer and installing software into phone.
-It's M2BUS cable.
-
-
-
-DLR-2 - cable sell with Nokia 9110 Communicator. It can be used
-to exchange date between phone and computer and installing software into phone.
-It's M2BUS cable, but can't be used with programs working with this protocol (needs
-some small changes - after them will not work original Communicator programms).
-
-
-DLR-3 and DLR-3P - cables for Nokia 7110/6210. Supports AT mode and FBUS.
-FIXME: MBUS too ?
-
-
-
-
Can I use DLR-3 cable with my phone ?
-
-
-
See post from gnokii maillist:

-
The dlr-3 CAN'T work with the older phones. this is because the
-converter in the cable is powered by the phone. this is done by the
-phone by raising the !mic-gnd! pin to vcc. if the cable doesn't
-repond on the mbus after 1 second, the power is dropped. a older
-phone doesn't do this, so the converter is unpowered.
-
-
To decide if a phone needs a dau-9 (the old one, powered by pc) or
-the new one (dlr-3) simply connect a dlr-3 to the phone. if the
-phone says "headset connected" it isn't capable of using a dlr-3
-and you have to change to a dau-9.
