I obtained Two More if these Cami Research Cableeye M3 M3U Cable Testers… I really do not need any more but i am a sucker for test equipment at decent prices.

Ebay Description in very good working condition LOL umm ok! Ebay seller


Cami Research M3U Cableys Cable Tester Not M4 or M3Z
After Inspection Both units needed USB Ports, One Needed a DC Barrel Jack, and One has a Fault. 🙁 looks like I get to investigate. Both are at Firmware V1.19 also.
Cami Research M3U Cableys Cable Tester Broken USB Port.
Here is the Fault On the Bridge Check (High Impedance). Bridges Between the Following Testpoints Pin 1-75, 2-75,  and counting.
When I get time I will look in to it and publish the fix. Sadly no schematics from Cami Research so I will need to make the time for in-depth diagnostics.

There is No Fault when self test is done on the first bank of 64 so the Issue must be in Bank 65-128 when I get time I will investigate.

Backed up the firmware off the C8051F230 Both These Units Filed away for Safe Keeping.
