Title: Reverse engineering the Fluke WireView identifiers
Post by: andtfoot on December 29, 2013, 11:36:58 am
After recently purchasing the Fluke LinkRunner AT 2000 (thanks to TopLoser  :-+ ), I looked at getting more of the cable identifiers. After seeing the price (>$400).... bugger that.
I thought I'd see if I could make my own.

I was fully expecting some termination resistors, and maybe an EEPROM with the identifier number stored.

Instead I got this (please excuse blurry phone pics; my camera is at work):

(http://andtfoot.smugmug.com/Electronics/Fluke-WireView/i-VvFSKt5/0/L/WP_000618-L.jpg)

I scanned the circuit board and whipped up a quick overlay:

(http://andtfoot.smugmug.com/Electronics/Fluke-WireView/i-hrNrQGB/0/L/fluke0002-L.jpg)

I'll be figuring out the circuit shortly.
In the meantime, has anyone got any ideas on how the Identifier number might be set on this? There are 1 to 6 available, and this is #1.

The value of the resistors, almost certainly.

Post by: dfmischler on December 29, 2013, 11:58:11 am
If it isn't the resistors then the units could be wired differently to the connector (i.e. three diodes could provide a three bit binary code quite easily).

Once you have a schematic I suspect it will be fairly obvious which parts will be used to distinguish units - almost certainly either a resistor value or a ratio of 2 resistor values,

I should clarify, the $410 is for a set of 5 (#2 to #6), but that still means $82 each...  :palm:


I tend to agree with the suggestions of the resistors being used to set the number. I've thrown together a schematic, but with no values yet. For some reason what measure doesn't seem to match the markings. e.g:
R1 (the one on the far right of the top picture) measures 25.07k, but marked 390 (39R) or 39C(?) maybe
R6 and R9 measure 10.6k, but are marked 1432 (14.3k)
R12 measure 3.836k, but is marked 57B (?)

I might pull a couple out of circuit to double check, but I wouldn't have thought these would be affected.

Letters are equivalent to digits : 57B = 572 = 5K7
Low readings will be due to the parallel combinations
A bit puzzled about the large R's, unless it's a test load for 48V PoE

Rightio, thanks.
I wouldn't have thought a resistor such as R1 would be affected by any parallel combinations. I'll have to double check after I've had a nap...
The Linkrunner measures PoE, but I don't think it spits out any. That said, these identifiers appear to be used across a few products so maybe something else does.


If I were to have a hunch based on an uneducated guess  ;D I'd say that the Schottky diodes are being used as comparators of sorts; the voltage dividers made by the resistors are used to set which diodes are forward biased.
Another possible theory is that the large resistors are being used as a precision reference (why else would you have series-parallel like that of the same value, apart from increasing power capacity). Maybe the comparison between this and the other resistors is done at the LinkRunner end.

First thing I'll probably do after figuring out values is breadboard it and see if I can get a copy working. Then I can tinker......

Ok, here is the latest with the values read off the components. I've also rearranged it a bit to try and find patterns in how the components are connected.

I finally found some schottky diodes and sat down with the breadboard.

I don't have the correct value resistors, so I tried the closest values I could:
(http://andtfoot.smugmug.com/Electronics/Fluke-WireView/i-sP6qxZ7/0/L/WP_000631-L.jpg)

Not close enough apparently...
(http://andtfoot.smugmug.com/Electronics/Fluke-WireView/i-P8SS2xX/0/L/WP_000630-L.jpg)

I'll get a bunch of the correct resistors and try again (and double check my breadboard mess  ;D ).
I couldn't measure the capacitors (value too small for my DMM), so I took a punt with 22pF ceramics. Maybe this is a good excuse to pick up an LCR meter, not that the value should be important.  :-DMM

Could all the stray capacitance/inductance of a breadboard be enough to upset it?

It's possible. I did connect the original module through the breadboard and it worked fine there, but it's obviously a lot neater.
I was hoping whatever signals it uses would be quite robust, given it may have to go ~100m of cable in normal usage. Some of the resistors are a fair bit out, so it can't hurt to try that first.

Thanks. The general layout looks like it will be easier to find patterns with.  :-+
It looks like I'll probably concentrate on the 4 right-hand resistors (R4, R11, R12, R15) to start with.
One small error though, is the missing RJ-45 shield and how the last diode connects to it.


On other news....

Like a bought one!  8)
I started by compacting it all and shortening the wires; no good. Then swapped the resistors out for combinations that got me within 100R or so.
It means I can churn out a bunch of #1 units if I feel like.

Next step will be grab some scope shots, and start swapping values. I might also disconnect a few diodes one at a time to see if them conducting or not is determining the ID.

First bit of random discovery:
(http://andtfoot.smugmug.com/Electronics/Fluke-WireView/i-PN9GkT6/0/XL/flukeschem2%205-XL.jpg)
I can get the ID to change from #1 to #5 if I disconnect this wire going to pin 3 of D2.

First scope shots, with ground on pin 8, and probe on pin 1.
Idle, there seem to be random pulses (which aren't there when the tester is turned off). Could be something to do with the network testing side of things.

based on the arrangement, try measuring across 4 and 5, i would imagine that should just be a fixed voltage,

(also i mistook that 9 to be 8, so the diode that curls around the right on my diagram is the diode to case)

I've had a fiddle around, swapping the 4 resistors going to the diodes, reversing the diodes, changing value of that series/parallel resistor set, etc.
No luck apart from that #1 -> #5 when disconnecting a wire thing (probably just coincidental) I posted earlier.

To be honest, I'm pretty lost where to start looking or what to try. Has anyone got any ideas they could throw at me please?


I've also ordered a batch of circuit boards from ITead matching the existing one. First time I have done that, so at least it's still a good learning experience.  :)

Hi AndtFoot !

I'm also an owner of a LRAT2000, it is an outstanding piece of equipment. I also share your thoughts about that those little WireView adapters are very expensive, and actually overpriced.

I also own a Microscanner2. Its included cap/lid is also the receiver, if used with the LRAT2000 it is detected a WireView1, i will extract it and photograph it for you so you can compare.

But i discovered something, the integrated reception port of the LRAT2000 (the lateral RJ45 port) is detected as Wireview 7 with the Microscanner2 !!!

I think that you should open your unit and verify that portion of the circuit, i think that you may find a clue there.

Hope that this project is still alive !
Title: Re: Reverse engineering the Fluke WireView identifiers
Post by: andtfoot on April 20, 2014, 01:50:39 pm
Well... after a loooong time, I've finally got around to looking at this again. Thanks for the suggestions in the meantime.

I ended pulling apart the main unit (goodbye warranty ;) ) to look at its loopback circuit.
It appears to be identical with the exception of R12, R11, R4 and R15 below (unit #1). They are double the value in the loopback.
(http://andtfoot.smugmug.com/Electronics/Fluke-WireView/i-P59dHRc/0/L/wiremap2-L.jpg)

This triggered a memory of a pattern I'd noticed earlier in unit #1:
The ratio of the the resistor leading to the diodes to the other resistor(s) that the diode is across is 1:5
e.g. R12 * 5 = R2,
R4 * 5 = (R3 + R8 + R5),
etc.
The ratio of the loopback unit is then obviously 1:10.

So I've ordered a bunch of resistors to suit ratios 1 through to 10; more experimentation to follow once these are received.
In the meantime, production of identifiers using parts I already have has begun......  :-/O

WireView Wiremapper Use and Interoperability - EtherScope
 
EtherScope ships with a far end adapter 1 labeled WireView.
 
The WireView far end adapter is used on installed cable links to obtain wiremap results.
 
EtherScope reads the adapter ID and reports the value on the Cable Verification screen.
 
Shown below are the wiremap adapters supplied with products:
•OneTouch
•OptiView Integrated Network Analyzer (Series I and Series II only)
•EtherScope
•LANMeter

Cable identifiers shown are all interoperable.

Well it's bee a while, and I just acquired a Fluke 620 LAN Cable Meter with the optional eight
cable-id plugs.

They look exactly like the cable-id plug that came with my  Fluke Lanmeter 683, but unfortunately
they are not the same beast.

The Lanmeter 683 reports mis-wired  ID when trying out the 620 cable-id plugs.
Trying the 'cable map' function reports open's and mis-wires on these id plugs.

The Fluke 620 reports invalid 'ohms' when trying out the Lameter cable-id plugs in it.

Not a 100% lost cause, as I can still use the 620 cable-id plugs as intended with the
620 cable meter for ID'ing unknown/unmarked cables.

Hi

Yes this is correct, I have a WireView number 1 as well, both are ID's appear as 1 on the units. I believe the extra components maybe for the F-Connector.

I am going to create a schematic this weekend to see how they compare to each other

Would be interested to know how the original poster removed the casing from the WireView with out damaging the casing, mine appears to be stuck in their.

Post by: coreyspeed on November 10, 2015, 05:56:15 pm
It  appears that the red section in the picture is R1 and R12 this is only connected to the F connector and therefore ID's this as number 1.

For the diodes I used the Broadcom HDMS-2802-TR1G schottky.
https://au.element14.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=43&urlRequestType=Base&partNumber=1056834&storeId=10184 (https://au.element14.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=43&urlRequestType=Base&partNumber=1056834&storeId=10184)
I don't how important the actual value/part is, just that it's a schottky.

For the capacitor, I think I used a 10nF or 1nF ceramic; I can't check at the moment though to confirm. I don't think I could ever actually measure it from the original.

Fluke Main Wiremap
Hello Andfoot, I have a Fluke Networks Cable IQ qualification tester with this main wiremap, but it has a problem, the tester not recognizes it, when I connect it at far end it appears like nothing connected. The problem comes out because it got connected to a POE Ethernet switch by a partner at work.  My question is? Do you have the circuit for this main Wiremap? I also need help with this component, which is marked as WK3 and is SOT-23 package, CG marking code 3 pins SOT-23, I can’t find it and I don’t know if it is a transistor or a diode. Thanks a lot

Hey y'all,
You mention these WireView identifiers, are those compatible with the OneTouch Series II. According to the manual the part number for those is: N6600/RA but those don't look the same as yours, but I read on eBay that the newer ones are compatible with most older fluke units. I am not sure if I want to go down the road of making my own off these schematics unsure of if it will work.
Thanks,

@andtfoot Thank you for your initial work with the schematic.

I've been needing to repair my ID3 and ID4 WireView Cable ID units (Broken tabs).

So as I had to de-pot them I have some more info, and I've also measured the loopback inside my LinkRunner AT-2000.

Resistors R2, R3, R5-10, R13, R14 are the same values for each ID and the internal loopback

The internal loopback only has a single 14K3 (R4) between pin 4 and 5, Where as the Cable ID units have 4 resistors (R6-9) in the parallel-series arrangement.
Its also missing the pin-9 shield test components (R1, D5, C5).

So the only components that set the ID are R4, R11, R12 and R15

ID0ID1ID3ID4
R44.32K8.66K21.5K34.8K
R111.69K3.4K8.45K13.7K
R121.91K3.83K9.53K15.4K
R152.15K4.32K10.7K17.4K

Has anyone else have values for R4, R11, R12 and R15 from other IDs?

R11  18.7K
R4    47.5K
R15  23.7K

Ive updated https://docs.google.com/spreadsheets/d/16VslfwP_YgZnVYq4AyuuF9MA8dwQInBXGkP8JXn2l00/edit?usp=sharing

I think Ive calculated the values for the missing ID2 ID6 and ID7
I have also seen photos of ID8 - ID12
Title: Re: Reverse engineering the Fluke WireView identifiers
Post by: morphis on October 24, 2024, 11:09:48 am
I now have all the values fro ID0 thru to ID6
These values are based directly on the SMD markings for ID1 thru ID6.
For ID0 (the internal loop back port) the values for R11 R12 and R15 are measure in circuit (forward and reverse, highest value is used), the measured values match the expected values.

#     |ID0    |ID1    |ID2    |ID3    |ID4    |ID5    |ID6
R121.91K3.83K5.76K9.53K15.4K21K30.9K
R111.69K3.4K5.11K8.45K13.7K18.7K26.7K
R44.32K8.66K13K21.5K34.8K47.5K69.8K
R152.15K4.32K6.49K10.7K17.4K23.7K34.8K

I think the following is the scheme is use to calculate R4 R11 R12 R15 for each ID

ID0 X 2 = ID1
ID0 + ID1 = ID2
ID1 + ID2 = ID3
ID2 + ID3 = ID4
ID2 + ID4 = ID5
ID3 + ID5 = ID6 ( R11 is only off by 700ohms from the actual marking on part )

These are all fitted to the E96 series at each step.
I've updated the Google sheet (https://docs.google.com/spreadsheets/d/16VslfwP_YgZnVYq4AyuuF9MA8dwQInBXGkP8JXn2l00/edit?usp=sharing) with the actual values for ID 0-6 and the estimates for 7+, you can see the function used to cal and fit the estimate.

Hi! I recently purchased a NetTool Series 2 on eBay, and everything works well except for the WireView wiremapper. When I connect it to the device, it shows an incorrect wiremap, as if the cable is improperly terminated.

Ordering another identifier is risky due to long shipping times and the possibility of receiving one with the same issue. Since I’m not very experienced in reverse engineering, I was hoping you could help me by providing a PCB schematic for the WireView identifier. This would allow me to have a replacement board made.

I came across your article and saw that you also have a NetTool Series 2. From what I read, you successfully designed and built a working schematic. That’s why I’m reaching out—your expertise would be incredibly valuable in helping me get this issue resolved.

I’d really appreciate any assistance you can offer!

Having spent another hour or so going through this very informative thread, my thanks to all the contributors, it seems like information on both the remote ID and the cable ID plugs are included.

If I've understood correctly, both type of ID plug share the same schematic, but using different circuit references and difference resistor values.

So is it a practical proposition to convert a cable ID plug to a remote ID plug, just by changing the resistor values?

Plus, how easy is it to break open the enclosure and is the PCB potted?

Well, I can scrub my last post, I'm pleased to say.

Having just purchased a new Fluke Link IQ, as well as a set of six second user WireView Cable ID devices, I'm delighted to report that they all work with one another.

It still left me wondering if the WireView plugs would work with the Microscanner 2, that I've had for a while, but I'm pleased to say they work on that too!

So, I'm very happy  ;D.

I just have to ensue that I don't lose any more of the ID plugs, as I have done in the past!

I hope that information is helpful to others.

Great topic, and thanks for taking the time to document all this. Much appreciated.

I came across this thread while looking for a compatible wiremapper for a first-gen Fluke NetTool.

Has anyone actually tried a wiremapper with the first-generation NetTool and had success? I’m particularly interested in the exact model/part number that works.

Also, if anyone has details on the compatible WireView/identifier part numbers, electrical specs, pinout, ID/resistor values, or any other compatibility information, I’d be very interested. Even info on third-party wiremappers that have been tested would be useful.

I’m trying to figure out what can actually be used with the older NetTool rather than just the later-generation units.

Thanks!
