Inspired by the IP industry where engineers have a huge resource of off-shelve tools and materials that they can call on to inspire new designs and easily create software to make things work, the Ethernet testing industry is quickly adopting an approach where testers are specifically designed to certify Ethernet.
Tests 12 - 1000V AC and includes independent, bright flashlight
The main area of use is in racks where service personel can reboot devices that are not responding. Apart from accessing via a browser there is an iPhone and Android app to allow service technicians to take action while on the go.
VDV MapMaster 2.0 can impressively map up to 19 locations, it still does utilize the tried and true tone generation. This gives techs the capability to adapt to the mapping features of the product while providing a great fall back when toning speaker wire and other miscellaneous cables. Now with the added TDR technology, it has the ability to both measure the entire length of a cable and or individual pairs, as well as measure the distance to a short in the cable.
Many of the projectors on the market today (all fixed-matrix; R.I.P., CRT!) have been specifically designed for home use. Part of the redesign for this market has been to significantly reduce noise, both from the fan motors and the movement of air through cooling passages. Nevertheless, some projectors still produce more noise than is acceptable in quiet theaters in which projectors are located close to the audience. There is also a desire in many cases to hide the projector for aesthetic reasons. So the client needs only a bit of noise reduction and perhaps a bit of camouflage. This makes life much easier, as a partial enclosure can usually achieve both objectives.
Well, it's been awhile since my last TIP. Sorry for the very long delay but there have been BIG changes since that last TIP that got me totally preoccupied. The problem was I completely ran out of TIP ideas, so I needed some fresh input. What better way than to start a new custom installation business from scratch. But since starting a CI business in the U.S. has gotten too easy and boring (and the market a bit saturated), we decided to do it in someplace more challenging. It came down to Afghanistan, Antarctica, or Turkey. Airfares were cheaper to Turkey. So after a year of hard work, the Europe/Middle East office of Training Reels/Training Dept. Seminars is now open for business, AND we're the proud owners of Cinema@Home in Ankara, Turkey (the capital). We even have a backlog of home theatre/custom installation work. This should definitely generate a lot more TIPS!
When setting up a home network, aesthetics are important to any installer. This is particularly true if that network happens to be located in your own home. For clean, attractive terminations, one option is to install wall plates that utilize keystone jacks for Ethernet connections. For small projects that only require a few jacks, an easy option is a toolless keystone jack. These do not require the use of a punch down tool like the 110 style keystone jacks.
This rack was an absolute breeze to install --- even for me --- so professional installers will have no problem whatsoever.

This is based on a tip I got from someone at the CEDIA EXPO show. Each year, BES Manufacturing does a retrofit contest in their booth. The contest consists of fishing a cable between two (of several) locations in a wood frame "set" in the booth. The best time of the day wins a prize. One of the fishing tasks requires feeding a ballchain down a wall cavity and retrieving it from a hole in the bottom of the cavity on the opposite side.
Drilling up or down, or fishing cable in insulated walls is an inconvenience but nothing
Installer/designers seem to associate the word "modulator" with "crummy picture". This is undoubtedly due to a bad experience in the past.
Every cable that you install on a job MUST be labeled. No excuses. Labeling will not only save you lots of time on the job site, but will greatly reduce frustrations of troubleshooting and service
This article is a great troubleshooting tip based on the "tool of a thousand uses", the good old tone generator, tone detector.
Keep the WAP as centered as possible in the living spaces where remote/portable devices will be located. Keep the antennas vertical! You want the signal to spread horizontally. Also, mount the WAP above eye level. There is just less stuff higher up to absorb the RF. If you put the WAP down low, the signal has to pass through furniture, people, dogs, etc. Keep it away from AC ductwork. This means not mounting it too high.
