I'm looking for a basic-level Ethernet cable tester that only checks the wiremap, gives pass/fail and preferably is <$100 and has a simple TDR.
It must survive Canopy 30V PoE voltage as it seems that many of the dead testers that we have in a pile are due to field techs plugging them into live lines. Monoprice $80 tester is OK but definitely does not survive the live lines. A test I'm considering is soldering ~15V zener diodes inside a unit to trigger a PSU's short protection before frying the cable tester...
