    Hey all,

    I was wondering if anyone here has a serial port working on their WAP54G ... if so do you think that you could take pictures of how you soldered and connected everything? I can't seem to get mine to work. I will also host pictures of mine and maybe someone can point out what is wrong.

    Okay, so let me explain how i have this wired.

    On the WAP54G, I have a wire connecting the +5V on the WAP54G to the +5V on my adapter. I also have a ground running from the Ground on the WAP54G to the Ground on my serial adapter.

    I then connected ttyS0 Out to Rx on my serial adapter, and ttyS0 In to Tx on the serial adapter.

    I soldered a wire connecting the two J3 connections, and then i connected all 4 J1 and J2 connections together.

    My serial port adapter is a CompSys AD233 V2.

    This is what it looks like:

    Heres a link to the product:

    I am unfortunately not an EE major at all... I am CS, i stick to software mainly, so any help at all with setting this up would be greatly appreciated.

    So I guess no one has a working serial port on a WAP54G ?

    wrt54 serial port

    I am afraid that your guess is wron

    the reply above just explained how to add and connect a particular TTL to RS232 converter, which he has

    many different TTL to RS232 converters are available from ebay, although there wireing is different, all of them is converts the wrt54G boards ttl signals levels to usable rs232 serial signals

    you need some basic electronics experience, since it will include soldering connectors/wires to the wrt54g board

    I have a fully working serial port with a wrt54g version 3, but having difficult time to get answer on this forum to find out if TOMATO has built in support for it ?

    does /dev/tts/0 exist ???????

    The explanation of how the serial adapter is connected to the WAP, is made by the OP; who originally said, "I can't seem to get mine to work". So naturally; I assumed that WASN'T the way to do it.

    I am aware that I can obtain TTL to RS232 converters from Ebay, and the like. What I'm not sure about; is WHERE to connect the wires from these converters to the WAP54G. I have a space for a DB9 on my v1.0 WAP54G (it is screen-printed onto the PCB). So my initial thinking was; just solder a DB9 plug onto the PCB, along with the necessary components/chips. Couldn't determine what the "necessary components/chips" were; so gave up on that idea. I'm no EE (I'm a Linux/Unix/SAN sys-admin); but I can't see how soldering to the DB9 holes on the PCB, would suffice. Surely the tracks from the DB9 holes go off to another area of screen-print, where there's another missing component/chip. In other words; there are gaps in the end-to-end connection, because of missing components.

    Just looking for clarification, on where to attach the Tx, Rx, 3.3v and GND wires to the WAP54g
