Their focus, as always, has been to deliver customer-focused innovation in the form of high-quality tools that contractors rely on daily. The Greenlee NC100 netcat micro digital voice, data and video wiring tester tests the shielded twisted pair, the unshielded twisted pair and the coaxial cables. It is able to detect shorts, opens, reversed polarity, crossed and split pairs. It generates three distinct, selectable digital tone patterns for cable tracing and troubleshooting. The tracing modes can be adjusted for high performance LAN cables. Review: Good basic tester, provides RJ-45 wire map and co-ax open/short info - I purchased the Netcat NC-100 locally. It is a handy tester for go/no-go testing of patch cords and wire runs. One end of the wire in question attaches to the RJ modular connectors or threaded coaxial connector on top of the unit and the other end of the wire attaches to the removable transponder stored on the bottom of the unit. Pressing the corresponding button gives a wire map of the modular cable or an open/short for co-ax. It is about as easy as it gets, and makes it very easy to spot misfires jumpers or cable runs. The main unit also has a built-in toner which can send tone on any individual wire or all wires together in a modular cable for pick-up by Fox ‘n hounds receiver or butt-in handset. The unit includes an RG female/female barrel connector, two RG to BNC adapters, RJ-41 to alligator clips, and short RJ-45 STP jumper. You’ll have to supply your own 9V battery. The Netcat NC-100 doesn’t aspire to do too much, but it is fast and accurate at what it does, plus it is small enough to easily slip into a tool bag. The quality is definitely better than the cheap testers that are just a row of blinking LEDs. The NC-100 is a good deal if you want a reliable tester, but don’t need TDR and attenuation data like you get in the NC-500 which costs 5.5 times as much. My only criticism is that the NC-100 does not come with a carry case which would have been nice to make sure the adaptors snd patch cords don’t disappear into a disorganized jumble at the bottom of a tool bag. I’m glad to have the NC-100 and I would buy it again if I needed another tester. Review: Cable tester - I am hardwiring my home network and some of the cables can get quite lengthy. This tester works great and has made it easier to verify the cables once I put the ends on. ## Features - FAST HIGH-PRECISION MEASUREMENTS: Tests shielded twisted pair, unshielded twisted pair, and coaxial cables. - ACCURATE: Generates three distinct, selectable digital tone patterns for cable tracing and troubleshooting. - RELIABLE: Detect shorts, opens, reversed polarity, crossed and split pairs. - PAIR TRACING FREQUENCIES: 577 Hz and 983 Hz.

This tester works great and has made it easier to verify the cables once I put the ends on. ### ⭐⭐ It works GREAT. It's a Greenlee *by R***. on July 13, 2014* This unit I rate with mixed emotions. It works GREAT. It's a Greenlee.. It should... HOWEVER, NOT having a On/OFF switch was a bad decision.. Touching any of the 4 buttons auto turns it on. The second time I went to use it, I had to replace the battery. Poor choice on Greenlee in eliminating an important piece... If they provided a case designed for it, it may of not been a issue but they did not. I kepted the unit and always try to pack it in my case in such a way the buttons are not touched.
