    Utility Pole

    There is a tech driving around town asking himself "where did I leave that roll of cable..?"

    On Premise Wiring Disaster.

    A good friend once told me, "chaos breeds opportunity". Lost's of opportunities there... good luck.

    Identifying a connected network cable

    Blinking a port works on low density switches, or when you don't have many devices connected. If you have three cascaded 48 port switches in a rack that are all fully patched with numerous active ports, blinking a port is dang near impossible to locate. the LinkRunner works well, and my guys...

    Industrial Tech question - Cable to pass DC voltage and serial comm

    There were a few automation devises that I've seen over the years that use the flat "telephone" wire for comms and power connectivity. Often the serial data speed would be 9600 baud or lower, and the power consumption rather low. A typical flat wire would have 28 AWG stranded wire. As such, you...

    Landline ported to Boost Mobile without legal consent

    I would start with the FCC and copy the AG. Its a fraud and identity theft issue, but since it deal with telephony, its likely in the realm of FCC enforcement.

    Is there a space between the -t and the hostname? Hard to tell in the post.

    Remodeling Data Cables

    The cabling company is doing the wrong thing. A splice is an emergency fix and will "work" initially, but is not a long term solution. It will cause numerous problems down the line. It is also likely, depending upon how they plan to splice the cabling, that it wont even pass...

    help with cat5e wire jack

    To be sure, punch it down as indicated and wire map it with a tester. Take pics of how its punched down and the results of the tester as evidence that it's wrong, then fight tike H*%@! to get them replaced.

    Fluke OTDR with non Fluke test cables

    It should not be an issue. As long as the launch and tail-end test cables are of the proper design for the system being tested (i.e. Single Mode, Multi-Mode), and the OTDR is calibrated with the cables to be used for the test, you should not see any issues.

    #1, cycle power to the camera and reconnect the BNC. #2, recycle power to the monitor #3, if not a factory cable, re-terminate the BNC at the camera with a new connector You mentioned that you had 4 cameras. Are they going to a single monitor? If so, are you going through a switcher, or...

    RS-485 cable VS. Cat-6

    Your installers do not know the difference between communications cabling and control cabling. The 22 AWG cable may be too small for the controls signal (voltage drop, current rating…), but it’s much better for the communications signal. Google cable capacitance and line speed. Cat-6 works...

    fibre cable

    One has to assume some things with the limited info provided. I assume this is to provide connectivity the additional location only? Not trying to link back individual devices/industrial controllers/ etc. over the fiber link? If going from one switch at the head end to a new switch at the...

    Fiber cleavers

    Some tools you can skimp on more than others. A fiber cleaver is not one of them. The better the cleaver the better the connection and overall fiber system quality/reliability. You will regret purchasing a cheap cleaver.

    OM1 AND OM2 FIBER CONNECTORS

    Depending upon the style of connector, the 62.5 micron fiber should not fit into an OM2 connector. The 50 micron will be too small for the OM1 connector. Even if you could get it to work, it would not last, and the connection would be spotty at best. Spend a little $ and get the right connector...

    Does anyone know what type of Fibre connector this is?

    An FC perhaps? It does look more like the SMA905 though. What type of equipment/interface is it mating to that you cannot change to modern connectors/panels?

    TCP-IP over GPRS with Modbus

    Typically… The Modbus TCP client will handle establishment of the sockets. The Modbus TCP server (your end device) should handle closing the socket should it become hung. The client will initiate a poll of the end device (server) which establishes the socket on port 502. Should the socket close...

    TO START OFF THANK YOU FOR ANY HELP

    The quick start guide directs you to set a static IP address on your computer to the 192.168.1.X network to access the devices. The default address of the units are 192.168.1.1. If your network/router is already defaulted to this address range, you may still need to statically address your...

    OM1 fibre patch leads 50/125

    You can, for short runs, but I highly recommend against it. For one, its out of spec; you will get degraded performance. For two, its sets bad precedence of doing the wrong thing for expediency/cost sake.
