You can use all of the same files and follow the instructions 100%. I'm not sure about the v1. I can confirm that everything will work on the WL-500gP v2.

So here I am one year after you posted you message to mightyhom.com, asking how your modification of the Asus 500gp worked out. I'm about to pull the trigger on getting the 500gp instead of the 520gu, and I'd like to be a sure as I can that Jeff's project steps will work on that model. Thanks for any info you can provide, and Happy Thanksgiving (assuming you're in the US :) Hi, Jack.

My experience is that almost no computers have serial ports these days. However, if yours does, there are a few options to use it with the router, as you have shown. Thanks!

I hope this circuit can also be used with USB-RS232 Converter. I have also tried a max232 based circuit feeding 3.3v supply to the circuit through router but it doesnt work well, as well as it is costy and time consuming. Hi,

Some of the traces broke off at the holes due to a cheap soldering iron, and it is difficult to see where the traces go to. I think I can do the repairs if I can figure out what the traces looked like before I screwed them up. Does anyone have a good drawing of the trace/via holes for these 4 pins?

The +3.3V pin has a fat trace connected to it on both the 500gP and the 520gU (despite the connector being flipped). I always double check to make sure I am plugging the USB-serial adapter in the right way, but now that I know a polarity reversal can fry the adapter I'll be extra careful. :-( Sorry to hear that, Jack!!!

Anyway the WL500gP has same 4 way header but check ground and positive!! they are the other way around on the WL500gP model, i learnt hard way and fried my first usb-ttl cable.

I'll check it again the next time I have the radio apart.

It was very useful to me. However, I understood that the TX on the board should go to the RX of the serial adapter, and RX on the board should go to the TX of the adapter. When I hooked up my adapter that way, it would not work. So I think you have the labels for TX and RX reversed on the board side....correct for what leads you hook up to the adapter though. Hope that make sense. Here's what I did with this information: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=338441 Thanks! Hi:

You will need an RS232 to 3.3V TTL level shifter, there are some mentioned here and on the forums. No, the serial levels are not compatible.

I powered it up from the router's 3.3V pin, i.e. Pin 1 (+3V3) to +VCC, Pin 2 (RX) to RX0, Pin 3 (TX) to TX0 and Pin 4 (GND) to GND. On the RS232 side, I hooked up the DB9F connector to RS232-0 header as follows: Pin 5 (SG) to GND, Pin 2 (RD) to TXD and Pin 3 (TD) to RXD. Useful interfacing info is here http://www.beyondlogic.org/ Note that the +VCC remains unconnected on the serial port side. I used a Nexxtech USB Serial adapter (2613297) but hookup to a regular COM port also works well.
