Tiny pcb approx 0.55 x 0.61 inches! Ideal for those projects that require an affordable RS232 I/O port. The kit Includes an SOIC Max232, four 1uf SMD tantalum capacitors, pcb and a DB9F connector. It accepts any TTL RS232 Rx/Tx signals. Requires 5volts DC. This pcb was originally designed for a custom DB9 shell which was a couple of mm larger than most DB9 hoods found in electronic stores. One could most probably make it fit in a standard hood by shaving the corners and edges.

5v version uses an IC232 and 1uf caps and the 3v version uses an IC3232 and 0.1uf caps.

Shown mounted in a DB9 hood

Note: AD232DBH orders. If you would like the 3v version please indicate that when ordering (only available with item #: AD232DBH .)

How do I reset factory defaults of BritePort 8120
I need to reset the factory defaults because for some reason I can not get to the configuration page using a browesr yet I cn ping the IP address of the router.

Are you plugged directly into one of the 8120 ports? Pressing the reset button, will only reset the inital user and password. Maybe you want to look at the manual for some ideas?

My screwed up my lan ip settings on my 8120 and it became impossible to access via. However, there *is* a console port.

Just remove the rubber rectangular plug next to the power switch to reveal a 4 pin connector. Order a A232DBH (Max232) *3.3 volt version!!!* (see end of message for ordering details)

Pins facing the back, from left to right:

-------------------
RX TX GND VCC+ (pin on Max232 board)

Open up a terminal program set to 9600 baud, fire up the router and login (admin / admin by default)...

Except for trying to identify the pins, this is a very easy project. There are only 4 wires to solder. I used a CD rom audio cable for the 4 pin connector on the 8120.

Telnet into the router. Type help. You can restore it from there. No need to reset it. If worse comes to worse you can unplug it. Leave it unplugged for a few mins.

NOTE: this is in response to the post by giannuzzelli
yes, but all of that assumes that you knew the ip or had a valid subnet. If the values aren't right, the router resets them to 0's and presto...no router intreface.
 

Caro amigo Horácio, leia o documento anexo, descrevo o circuito para o
cabo console do 8120, e funcionou 100%, mesmo sem o MAX 232, pois estava sem
no momento, então providenciei um outro circuito facilimo de ser montado.
 
Verifique tambem, informações sobre o 8120 e o RTA300 serem identicos.
 
Quando tiver mais documentação te envio. Abraços. Papi

Particularmente, utilizei o circuito abaixo, por não ter em mãos o MAX 232 e funcionou 100% a utilização do console no Briteport 8120, ou RTA 300

Outra informação que obtive: Tem pessoas, usando o firmware do RTA300 (do concorrente), no 8120. Acho que o 8120 é clone do RTA300, sendo que o RTA300 possui muito mais recursos de configuração em seu firmware. Veja abaixo:

8120 Firmware upgrade -- 8120 ~= RTA300
»


I used the RTA300 for NZ, so far so good.

I was having problems with my connection on the original firmware from Covad.

I'm located ~9000 ft from CO.

Line Attenuation was at 57db
Noise Margin 7 to 7.5

Modem trains at ~5000 m/bits with low CRC errors and Error Seconds. At night the numbers jump to a ridiculous amount, ie ~10 to 100 CRC errors per refresh of the DSL stat screen.

Covad reported no problems of course.

So fed up and not wanting them to drop my speed I dug around and found the RTA300 firmware, so far 4 hours of uptime and looks good. Real test will be tonight.

Now DSL port stats report:

Line Attenuation 47 dB
Noise Margin 7.5dB (steady)

Standard disclaimers etc.. I take no responsibility.. yada yada

Note: Does anyone know how to backup the original firmware? (too late for me).

Also mibs for the 8120? I'd like to track my CRC, Train speed, and time to have documented

 

 

 

Por essas e por outras, a conclusão, e ser clone do RTA300 veja figura abaixo:

Pela parte traseira, observam-se a mesma disposição das portas ethernet, console, alimentação e reset, exceto pelo modelo dynalink ser USB também, e sendo suprimida uma das conecções de telefone no RTA300. 

Verificando o manual do RTA300, observa-se que os menus de configuração são idênticos, apenas em disposições diferentes, e até com mais funções. 

Analisando também os firmwares decodificados, observa-se compatibilidade quase que total. 

Outra prova, é em relação aos modelos: 8120 = RTA300 e 8420 = RTA300W wirelles.


Horacio, apenas acrescentando, nas informações enviadas, os seguintes dados:  

Ao acessar (ligar) o modem com a console ativa (hiperterminal aberto), aparecem as informações do BootROM.

No caso do Broadxent, aparecem informações com o nome de Askey ou seja, o Broadxent possui o BootROM da Askey Computers (Dynalink) .

Lá tem todas as instruções para se fazer a gravação ISP.
O problema é montar o gravador e fazer o software de gravação sem
experiência em eletrônica e em programação.
