my e2500 is currently stuck in a bootloop and not taking the tftp upload.
I figure this weekend I'll crack it open and do a serial flash to get it back up and running but a quick search hasn't revealed the pinouts for the serial port for that specific model.
Does anyone have a reference to the pinout and/or know if it's the same pinout as one of the other models that does have a reference?

I know this is an old thread, but I have been searching for quite some time without success to find the aforementioned pinouts. I don't have much experience with physical circuitry, etc so I was hopping someone would be willing to provide me a bit more detail. Here is a picture of my E2500 opened up.
1 - Which set of holes am I looking at, and
2 - In barryware's description of the pinout order, is that top to bottom, left to right, etc?
Or can someone help me find the thread with this info? I have searched, but just can't locate them.
Thanks!
(I figured this was a good place to put it since future searchers will likely find this thread in 5 seconds like I did).

Serial appears to be those "five holes" next to the "big square shiny thing". "Square" circle one will be vcc. Look carefully at the holes and you should see one is square. Solder in a header. Attach a lead and see the "serial recovery" wiki article. _________________ SIG:

Anybody got a descent High resolution pic of this PCB? If so PM me.
If still needed, I will take pictures of my E2500 serial'd with my iphone and upload them.. It is simple to do and takes 5 minutes tops. The parts are super cheap to make a serial console.. If anyone needs me to post where I got mine let me know..

ok. 2 more questions on this
#1 - I noticed last night there is another set of 5 pinouts, on the board that I didn't see before. If the LAN ports are are on top, these 5 run vertical and are below the large silver square (CPU or whatever it is). The pinout row from my previous picture is above the the silver square and run horizontal (again with the ethernet ports on top). Which set is it? Did i get the right ones the first time. Is it #1 or #2 in this pic?
#2 - I see alot of info about using the CA-42 Nokia phone cable for serial. However, I also found a post referring to using one of these:
http://www.amazon.com/gp/product/B006JKNWLE/ref=oh_o02_s00_i00_details
Will this work? Has 3.3v, seems much easier that splicing a cable and check voltage on the wires...
@Daemian - A level shifting ttl adapter will work. See the serial recovery wiki for information on different devices, and the linked everything you wanted to know about serial thread.
Figuring out the proper wires takes about 1 minute with a ca42. _________________ SIG:

So back question #1 from this morning

Fair question. Both look like serial to me. One might be a USB connection? Since I don't have that router, I cannot say for sure. You might have to do further research if no one responds authoratively. Barryware is most likely to know. _________________ SIG:
