    Compaq NT4

    Sorry, but believe it's a good candidate for the trash can. Restoration CDs are customized to find the hardware it came with. If they cannot find it, the installation will not go through. Yes, if you can find the configuration files, and change them to your particular hardware it might work...

    Switching problem

    Believe there is no satisfactory solution for your problem, the way the system was designed. First, you must understand that a hitless system with a moving target is simply impossible (actually, it's two, since the platform will move significantly too). No matter the current technology used...

    Connecting two Computers using Twisted Pair Cable

    Check your rights, you should allow the remote user to have access to the folders you want to share RA

    Windows Embedded Sys.

    You can start looking at www.soekris.com Nice little thing, mostly used for networking applications, but has plenty of interfaces and peripherals to play with. RA

    Wireless Network

    For an Office Environment, the answer is simple: get an Access Point and wireless cards for each node (802.11b should do fine). For range, antenna type and location are the keys. The farthest node is likely to require an external antenna. Now, in an Industrial Environment, it may not be that...

    transmission on 2.4 -2.5 ghz

    2.400 to 2.485 GHz is an ISM band, so it's license free. The equipment you need will depend on the purpose and interfaces you need, but you can look at www.wavewireless.com for some options. If you don't have technical expertise in link design they will help you with it. RA

    Wireless transmitters and antennas

    Use an 802.11b Access Point and web cameras. If you need Zoom and Pan, use video servers, they provide output to control them. RA

    Fiber Optical Cable to replace CAT 5 Ethernet Cable

    Agree about multimode fiber, the standard multimode is 62.5/125, and you must make sure you buy the right connectors for it. Better hire a certified FO installer, since making the connectors is not a piece of cake. What I would rather suggest is try to avoid getting material from different...

    howto: Simulate a modem or make a virtual modem w/ loopback device?

    Maybe you can fool the software with a loopback connector. You can build one using the following wiring: http://www.loop-back.com/null-mod.html RA

    PLC vs RTU

    Either you use PLCs or RTUs, you NEVER-EVER connect them directly to test points. CTs and PTs are used to bring the measured level to a standard range suitable for input to any device. If the devices you're using by any chance are to be connected directly, is because the CTs and PTs are inside...

    PLC vs RTU

    Just something to add to robertjo24's comment. It's not matter of what is cheaper or how many registers it has. It's what the run inside as Operating System (OS). PLCs are sequential devices, so they run sequential OS inside. Serial communication is a major headache for them, if the...

    round vs flat shielding wire

    The flat braided conductor is usually used to conduct RF energy, since it propagates on the skin of the conductor. It's mostly used for grounding structures on heavy RF environment, or to enhance the shielding of an enclosure. RA

    Terrain Factor???

    Hi Vilko Depending on the model you're using to calculate the losses, the terrain factor is a number which should include the geoclimatic and particular terrain factors that will affect the propagation. It's usually significant in long haul links. If you can get a hold on the ITU recommendation...

    LAN wired advice

    Carlos, Robertjo's warning is real. That's why I suggested that link. They don't use WEP or DES encryption. They use AES, which is the new NSA standard in US for wireless, non-confidential communications. Ricardo

    Who can make this? I will pay $$$.

    Guess this is not the right forum for your post. Why don't you try at the Automation & Robotics?

    LAN wired advice

    Carlos, Linking different buildings implies grounding problems, I wouldn't use copper wiring. As previous answers recomend, use fiber optic adapters to link the buildings, and rather use switches. If the distance is beyond the capacity of the adapters & fiber available, or digging trenches not...
