Terayon modem, interne serial poort !

Dames en Heren,

Wel eens de Chello Terayon modem open geschroeft ?
Hier zit namelijk een interne console (db9) aansluiting op het "moederbord", kreeg er tot nu to alleen maar abra-ca-dabra uit.
iemand nog ideas of tips ?

PS zal nog ff zoeken naar een foto !

Jah... (niet doorlullen he )
Het is zo'n...ehh...vaag ding...

Wat heb je dan geprobeerd? Een RS232 monitor aan te sluiten?
Of direct aan de pc? Met welke instellingen? Baudrate, # databits, # prioriteitsbits, even/odd
Of heb je maar 1 ding geprobeerd?

Meestal staan zulke dingen op 9600,7,1,N Dat al geprobeerd?

Ik heb van alles geprobeerd, kreeg op een gegeven moment wel rare sh*t voorbij.

instellingen stonden toen op 9600,8,n,1

Als ik soon tijd heb zal ik wel een aantal tests doen en fotos posten !

Ok, als het er interessant genoeg uitziet zal ik um ook openschroeven

Heej... ik ben wel benieuwd naar die foto's....

is het niet zo dat als je op 8,1 rare schijt krijgt dat het dan op 7,1 er wel es heel leesbaar uit zou kunnen zien?

Hi everyone.

I found the way to connect to the TeraPro cablemodem using a 3wire
serial connexion.

Here's how to proceed...

1 - Open your modem, place it so the coax connector points towards
you.
You'll see a ten pin connector near the status LED... here's the
pin-out:

1 2 3 4 5
X X X X X
X X X X X
6 7 8 9 10

1 : TX : Data sent to your PC/interface @ 9600,8,N,1
2 : +5V DC (used for CTS/DSR I guess)
3 : GND
4 : unknown
5 : +5V DC (used for CTS/DSR I guess)
6 : N/A
7 : RX : Data sent to the modem
8 : +5V DC (used for CTS/DSR I guess)
9 : N/A

Please note that only pins 1, 3 and 7 are important.

2 - Unfortunately, the modem uses +5V TTL signalling, so it's
impossible to connect it directly to your PC...you'll need a 5V/12
converter. It's really easy to build it with a Maxim MAX232 IC and a
couple of capacitors.(there are a lot of schematics available on the
net or you can just use Maxim's datasheet)

3 - Connect your modem to your PC :

PC <-------> MODEM

TX <-------> RX
RX <-------> TX
GND <-------> GND

4 - Open your favourite terminal proggie (such as HyperTerminal), set
the connexion parameters to 9600/8/N/1 and press ENTER...you should
now see the modem's shell prompt. Enter "?" to see a list of commands

5 - You can switch to admin mode with "SET PRIVILEGE ADMIN". The
password is "password" by default. DO NOT ENTER "SET MODEM STOP"
!!!!!!!!!
