Reverse engineering the Fluke WireView identifiers

[andtfoot]

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.


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......

Just passing on some information, might be useful. I have a Fluke Lanmeter 683 and asked user Khashoggi
who also has/had a 683 a question on ID plugs (search for 'Lanmeter 630'  in Test Equipment).

I am happy to report I have identifiers 0,1,2,3,6 (similar small form factor)
And identifiers 8,9,11,12 which are double-width of the other
small form factor identifiers.

You appear to be using the T568A wiring so that is what I will
use. I'm using a Fluke 45 for these measurements and am rounding
from the thousands to the tenths-

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.

Some success! 

Tried a ratio of 6 first up (first number I pulled out of the bag of resistors).
No good.

Tried a ratio of 3, which led to...

ID of 2 found! 

Further testing of other ratios to follow........

[andtfoot]

Further testing of other ratios to follow........

Results of the rest of the ratios I bought resistors for are in:

ID	Ratio
1	5 (measured and based on original)
2	3
3	2
Loop	9
Loop	10 (measured and based on original)

When I get some time again I'll try some ratios between the whole numbers (e.g. 1.5).

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.

[menkelis]

I now have a official set of 0 - 6 "cable identifier" plugs for my 683.
I opened up the ID #1 plug to see what it was like inside and have attached
a photo of it.

[coreyspeed]

I was wondering if anybody ever got any further on this project, I have just purchased a Fluke linkrunner, and would like the extra remote's, it looks like I can make ID's 1-3 and then try and produce the other values.

Also would you be able to provide the values used for ID 2 and 3 for resistors R12,R11,R4,R15. My Maths doesn't appear to be getting anywhere near the values for wireview 1

[coreyspeed]

Got hold of the Fluke Microscanner at work today and the WireMap top on the unit comes apart very easily.

Measured the capacitors and they read at 22pf.

Took some pictures appears to have more components then the listed on this thread.

[kamcm]

Coreyspeed, the item you pictured is a main Wiremap adapter instead of a WireView identifiers.

======
May you please post more clear pictures with it?
I want to make one on my own. 
I recently purchased a Fluke CableIQ tester off eBay, but it didn't come with a Wiremap adapter.

Thanks

[coreyspeed]

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.

[coreyspeed]

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.

[timofonic]

I'm really intrigued about this. I didn't know there was so much tools for cablee impedance and such.

Could someone provide a layman introduction or  URLs about all this? Please, I'm curious...

[turbotim]

Hi There,
I know its been a long time, but did anyone manage to crack this one?

[andtfoot]

Hi There,
I know its been a long time, but did anyone manage to crack this one?

It's on my very long 'rainy day' list, but the 4 IDs I figured out of 7(?) possible is enough for my purposes so it's relatively low priority at the moment.

[sayit]

CableIQ wiremap tested
RK45 8pin
attach cable with WM Autotest->Port or cabling short Autotest not available
not join WM Autotest-> without wire map test OK
DIAG—>Continuity test all OK
Blinking  port light test OK
Telco 2pin (4-5)
attach cable with WM Autotest-> not find wire map continue no WM-> then yes->cable length ok

COAX
AUTO TEST MAP ID are “?” other OK

teardown main unit without LCD unit and checking use microscope
clean PCB board resolder any parts..
same work wiremap unit
But a not changes result.

Whats happen? please your help.

Has anyone confirmed that this circuit is the same as the Remote IDs Fluke makes for the MicroScanner2?

[cmu2017]

Does anyone know how they check if some wires are crossed?

[jasom]

Hello, have someone photo of Fluke Microscanner2?

I have one with damaged one zener diode but I have not information about that model. (VR1 position)

[cmu2017]

What are the values of the diodes and capacitors on the  schematic made by user andtfoot

[andtfoot]

What are the values of the diodes and capacitors on the  schematic made by user andtfoot

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
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.

Ok, thanks

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

[KuchateK]

Hello, have someone photo of Fluke Microscanner2?

Just dropping pic of the VR1 if you still need it. I have same rev on the pcb as you.

Quick measurement: 3.3v on the plus side relatively to battery negative terminal. Let me know if you need more measurements.
