Is this one corrupt ?

No, it is quite innocent and pure.  :P  ;)

For those who don't want to solder to the PCB, maybe a strip of right angled header pins could be taped temporarily to the UART solder pads.

This was just tried, using a Prolific Logic pl2303 USB-UART adaptor (cost 1.50 inc P&P from ebay):

See: http://www.ebay.co.uk/itm/180836792643



Adhesive tape isn't strong enough to hold the header pins onto the PCB pads.

But Dolly the clothes peg proved just the job! She is electrostatic-safe, too  :D


The Linux device driver for the pl2303 has been included since 2.4 kernels. The Prolific website in Taiwan carries (binary) drivers for Windows and the Macintosh.

Installing the pl2303 driver for Windows. 


Now, finally, we can log into the ECI modem via the serial console:


cheers, a

I was happily looking through this thread until I came across the last four images.  :(   BGW? Yucky!  :tongue:  It's put me right off my evening meal.  :'(

I'm impressed. True hardware hacking in it's purest form.

Sir, I salute you!

Apologies to all for the cat-cursing at around 0245 hours today, b*cat was very frustrated.  :-[

An ECI B-FOCuS modem was upended.
It's rubber feet were removed.
The four screws, so exposed, were undone.
The case was opened.
The PCB was removed and placed on a firm insulating surface.
The PSU was attached and the modem was powered up.
Application of meter probes to the four pads at location JP1 showed with negative probe on pad #2 from the left, 3.28 VDC on pads #1, #3 & #5.
Confirmed #2 is GND, #3 is VCC, #1 & #5 are TXD & RXD.
A block of five 90 degree header pins had leads attached.
Jake (the peg) was encouraged to hold the block of header pins against the solder infested pads.
The cat cursing started.
No matter how things were tried, no continuity could be obtained from the PCB solder pads to the ends of the fly-leads.  :(
Tiny dimples were gently made in the solder infesting the pads.
The cat-cursing got louder.  >:(
Offering up the header pins into the dimples was finally achieved.
Still no continuity.
The cat-cursing reached fortissimo!  >:D
The soldering-iron was considered . . . and rejected.
b*cat's paws are now too fumbly and the vision is not good enough for such micro-surgery.
Fifty years ago and things were considerably different . . .  :'(
I'll just have to wait for the software unlocking method to be resolved.

And now I've just seen the time. Well overdue some  :sleep:

Hello burakkucat!

..

Tiny dimples were gently made in the solder infesting the pads.
..
Offering up the header pins into the dimples was finally achieved.

..

Damnation!

No continuity? As in no electrical continuity, according to a multimeter?  Or no connectivity on the serial port?  If the latter, does the pl2303 adaptor definitely work? I've had two or three which were duffs. There's a spare adaptor here if you need it, or happy to solder-in the pins if you dare entrust Royal Mail* with it?!

The tails of the right-angled header pins were facing inwards (away from the nearest PCB edge)?
And a good quality peg was used? Definitely the correct model? Type A rather than the Type B?!


cheers, a

Yes and yes.  :(

I thought a pl2303 adaptor required usage of BGW? Though there is a driver in the Linux kernel --

Quote
[bcat@Duo2 ~]$ find /lib/modules -name pl2303.ko | sort
/lib/modules/2.6.32-220.23.1.el6.x86_64/kernel/drivers/usb/serial/pl2303.ko
/lib/modules/2.6.32-279.5.2.el6.x86_64/kernel/drivers/usb/serial/pl2303.ko
/lib/modules/3.5.4-1.el6.elrepo.x86_64/kernel/drivers/usb/serial/pl2303.ko

As both my laptop and workstation computers have serial ports (I would never be without one), I have this RS232 to TTL Converter Cable (based on the ST micro ST3232EC chip) for the job.

I may eventually take advantage of your kind offer. At the moment, I am a little bit concerned that your Wayne may come across it and decide it would be useful currency with which to obtain two cans of Special Brew:-X

Yes, a Type A of plastic rather than wooden construction. You don't think that is the cause, do you?  :-\

The pl2303 works fine on Linux. The kernel driver automatically inserts after the device is enumerated, and the dumb USB serial device becomes available as ttyUSB0

Code: [Select]
Sep 25 22:58:26 l502x kernel: [353464.425850] usb 2-2: New USB device found, idVendor=067b, idProduct=2303
Sep 25 22:58:26 l502x kernel: [353464.425855] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
Sep 25 22:58:26 l502x kernel: [353464.425858] usb 2-2: Product: USB-Serial Controller
Sep 25 22:58:26 l502x kernel: [353464.425861] usb 2-2: Manufacturer: Prolific Technology Inc.
Sep 25 22:58:26 l502x kernel: [353464.427931] pl2303 2-2:1.0: pl2303 converter detected
Sep 25 22:58:26 l502x kernel: [353464.456013] usb 2-2: pl2303 converter now attached to ttyUSB0

The serial terminal program minicom is run:

Code: [Select]
$ minicom -D /dev/ttyUSB0

and away it goes..

The peg I used was of the very highest (Tesco Value) quality, but it did have a powerful snap to it.   Yet when the trick was tried again just now, exactly the same problem occurred as you found.  Though after giving the pads a scuff-up with my fingernail, everything worked okay once again.  So maybe it's down to solder oxidisation?

Perhaps if you have the patience to try it again, maybe the pins could be clipped to the pads on the underside of the board. These are actually plated thru-holes, so there should still be continuity.

ben1066,

I'm happy to give you FTP / website space if you want somewhere to host your eDMT with no bandwidth frustrations or intrusive advertising! Pop me an email on kitzedmt@sioned.info

I have a quick query with eDMT too. When on the same LAN I can connect to the vdsl modem with eDMT but if I am not on the same subnet, and NAT to it.. I can't connect and eDMT crashes after clicking connect. Any idea why routed vs. on subnet should make a difference?

Hey,
Great to know people are still interested in this. I can only assume that that is a modem limitation as telnet is fairly simple, I don't see why it'd fail. All code can be found at http://curlybracket.co.uk/misc/edmt.zip though thanks for the offer of hosting.
Enjoy.

Downloaded and will have a tinker.

As far as I could see from a packet capture the compiled program was trying to make a SMB connection to the router! Not even trying telnet.

After a lot of "cat cursing" throughout last night, I finally managed to unlock one of the original ECI B-FOCuS modems (supplied by Openreach as the alternative CPE to the Huawei HG612 modem) by following the published instructions to the letter. [1]

As Firefox is the only browser I have installed, I was unable to call up the device's buggy GUI and so telnet access was used to confirm that successful unlocking had been achieved.

Code: [Select]
[bcat@Duo2 ~]$ telnet 192.168.168.168

I have provided that rather extensive example, above, as it shows how to turn off the Beatie Group's "busy-body", the BTAgent. Once terminated, that "unknown quantity" will remain disabled until the next power-cycle or reboot of the device. (The same technique can be used to disable the identical agent that executes within the Huawei HG612.)

Has anyone determined if the device's IP address can be changed via telnet access? By default it is 192.168.168.168 and I would like to reconfigure it to be 192.168.1.254, for consistency with my other modem/routers.

  As per the Asbo instructions it can be changed via telnet but I did not find how to make a permanent change via telnet.  The GUI does however let you make the permanent change which survives a power on and off.

Thanks for that confirmation, Les. I can see I missed typing the word 'permanently' in my previous post --

Ok so I would really like to unlock my eci modem but a bit confused on how I have to do it

I know you can get the usb ttl converter off ebay but I would prefer not to spend any money if I can so can I just hook the modem straight up to the com port on my asrock z68 extreme4 gen3 mobo?

Pinout for the com port shows RRXD1, TTXD1 and ground so that's all that's needed right?

Also running windows 8 so is it easy to do from windows? which software is easiest and compatible with windows 8 to send the commands?
