    Extending all Cabling with SimMan/SimBaby upto 100m

    Hi,

     Today we used a Extender device that all the cabling of SimMan & SimBaby laptop plugged into, this included the serial port, VGA, USB, Sound, it then sent the above signals via a set of 2 ethernet cables to another receiver (which said could go upto a 100m away) when tried it worked perfectly all functions worked on the manikin, sound and also the VGA on the monitor.

    Has anybody else had expirence of this or is this a first?????

     

    Regards

     

    Craig

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    Hi Craig,

     

    I believe this may be a first to send all cable signals through one device,
    I have been sending the monitor signal from the pt monitor through a RGB/video distributuion amplifier in to a multi image processor to allow picture in picture overlay for some time noe but not all signals.

    This allows me to view the pt monitor screen on top of the video image of the scenario nand allow the candidates to watch there performance with the additional information of what the pt's physiological data was diong throughout the interventions.

     regards

     

    Neal.

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    Hi Craig

     It is not something we had to to do with Simman 1 but something we might find necessary with Simman II, if we decided to get the new software and monitor, with the additional VGA and USB and Audio Cables. I have looked around at some of the products that might work but was wondering if you could tell us more about the Extender configuration and specs you used?

     
    Thanks

    Jacques

    Hi,

    I now have a document which lists all the details on the USB mini extender and where to get one from, this will complete the job no problem, and works well as i have just found.

    If you require this then please drop me a email craig.henshaw@laerdal.co.uk and i will forward it on, i will try and get it on the download page but may take a few days.

    Regards

    Craig

    Hello All,

    I have been looking on various search engines on the net and I have now seen lots of other comapnies entering into this field of extending USB and serial cabling, so please may I urge you to take time to use a search engine and see whats on offer as there are many out there and you may find one thats better use for your needs.

    Regards,

    Craig

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    I still wrote it on the "USB-Cable"-Threat ..... well, here some ideas.

    Why don't you use a KVM-Extender with USB-Ports?
    The advantages would be that you can transfer more and different signals

    1. Video-Signal (VGA / Vital-Data)
    2. Sound (Monitor & SimMan or SimBaby)
    3. USB for ELO-touch-functionality and USB2Serial for connection to linkbox.

    AND .... they can extend all signals up to 200 meters !!!!

    Here some tested and good Products:

    • DVIVision (100m), VGA, USB, but without sound
    • LEVUE/52A (50m), VGA, USB and sound

    For those who wanted a good "normal" KVM-extender without USB, e.g. for having access on a PC ...

    • AdderLink X Gold (200m)

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    Would you mind providing the configuration information you described?  Hardware, cabling specs (when deviating from the default SimMan/Baby specs & cabling)?  We are in the planning stage of building a new simulation center along with the rest of our Nursing department.  I may have additional ideas to contribute to this discussion once I have had a chance to review your setup.

    Thank you.

    Nope.  Not a first.  Extenders from a control room or space from across the room have been used for a bit now.

    The information I could really use now, is a way to extend SP02, and BP cuff calibration tubing.  Laerdal Technical Support doesn't have a solution for this.  I am wanting to get the link box farther away from the "staging area."

    Anyone have ideas?

    Michael,

     

    I think what is unique about this is that he is only using two ethernet cables to do the extending.  I also have had my control room some distance from my Sim Man for several years; but, it's all hard wired with extensions for each cable.

     

    of course, as you mention, the link box and compressor stay near Eric (as we call him normally)

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    You are correct.  In our current control room we had to extend each signal separately like yours as well.  In our new building, soon to open in December, we are using the extenders to extend vga, usb, audio and serial over two cat5 cables.  Much better setup, and troubleshooting will be much easier should there be a failure.  The extender we are going to install is made by Geffen.  Too bad that it doesn't extend serial as well, but understand why they aren't supporting that dying technology.

    Before we learned about the Geffen extender (there are other brands, but this is a real good one), I was already aware of other extender type products, but had never thought to use them in this type of context.  Raritan has been extending signals over cat5 for at least a decade, if not longer, but this was meant to be used to take control of a remote computer on the network.  Even the Geffen functions much like a Zero client, which has only emerged in the last year or so.

    The Zero client basically utilizes an add-on card in a computer to extend up to two monitors, USB and audio anywhere on the network or anywhere in the world, when used with the Internet.  It would be conceivable with this technology to have a computer in a local facility, where it can be serviced, maintained and most importantly, secured, but allowing a user to connect to it using the zero client (similar to a thin client, but has no operating system or moving parts).  The Zero client box has two DVI output ports for two monitors, several USB ports where a keyboard, mouse and any other USB driven peripherals could connect.  Literally enabling full speed performance at a remote location.  The Zero client runs about $500 and the control card for the computer is a couple hundred, so the price isn't justified, since you can replace a PC for about the same amount.  However, in time, larger simulation centers, with multiple locations could very well have a central location for all client computers, and control rooms can be placed anywhere, and most issues be resolved in the hosting facility.

    I hope I didn't sound critical of previous posts.  I know that this is all new to many who visit this forum, and didn't mean to imply that the post was not helpful, or even new.  I just didn't look closely enough to see that the medium for connecting to the link box was cat5.  That is new for most.

    Response to questions is a bit slow at times using the forum, but I do try to help others, and seek help here often.   I appreciate you clarifying what is unique about his extenders.  It confirms all the more that we are moving the right direction with our new facility.

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    Hello, interesting reading through the issue of extended cabling!  I work within the Primary Care Environment using Simman and can run scenrios at distance using remote access software from any computer within our organisation.  Although, I do most from my own computer within my office some 30 meters away.  This also includes a tilt, pan and swivle ceiling mounted camera that allows me to observe all psychomotor skills.  May be worth considering approaching your IT dept for remote access software.... Hope this helps.  Jim Milligan.

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    I use several different kinds of remote access software, all of which work great except that animation and video is extremely choppy.  The more activity on the screen, the more quality goes out the window.  The reason for using other means of extending cabling is that you get a clear crisp image, and when you click on an control, there is no doubt that you have succeeded, so no double click of events, which could cause exponensial reaction depending on how the event is programmed.

    Video over remote desktop doesn't satisfy me at all, although with the right client software installed your local machine can receive actual video, instead of just the screen capture.

    That said, remote desktop software is not the solution for most people.

    However, there are some IP-based extenders that could leave a computer near simulator, but allow the user to control it and interact with the computer as if they are in the same room.  FX100 by Dell is one of them, allowing a user to connect to computer, with full-computer performance, from anywhere in the world, when routed through the web.  However, pricing makes that solution one to use sparingly.

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    Fair comment Michael.  I am fortunate in that all is connected through our network system and I am able to take full control of the remote laptop supplied with Simman.  If I wish to use outside this network i.e. via web then full security is required.  I use a Tanberg touch screen system for video control when in my office which is within range etc.  No beating direct cabling I agree, but remote access software may be a solution for some.  The video quality via Macbook Pro Laptop appears to cope well at distance.  However, I do appreciate it is very dependent on the users system.

    Re: Extending all Cabling with SimMan/SimBaby upto 100m

    I've just completed a small Sim Center here at the University of Texas, Pan American.  We have four of the wired simulators, specificially 2 SimMan, SimBaby, SimNewbie, plus a couple of 3Gs.

    I had been reading and been advised to extend cabling for control of the wired manneuins, but before doing any of that I wanted to attempt remote control over the network.  We're using a gigabit LAN.

    After evaluating many different packages, I chose TurboVNC.  VNC is virtual network computing, which allows a remote user control over a computer.  By installing the TurboVNC server on the mannequin machines to be controlled and the viewer on the machine that will do the controlling.

    By reducing the polling rate (rate at which the screen is rebroadcast) to continous every 50ms, I reduced the lagginess of the video refresh to near negligible. Patient monitor and the lungs on the mannequins graphical animations are smooth remotely and the mouse is responsive to checking actions students have done, etc.

    I'd suggest giving it a try.  TurboVNC is free under the GNU license and is availabe at http://www.virtualgl.org/Downloads/TurboVNC.  It supports multiple monitors, as well, if you need to view the secondary (patient) monitor.

    The downside is there is no audio support with the VNC protocol, but for now I'm using canned sounds on the mannequin control PCs.  There are many other packages that do support audio and are just responsive using different protocols than VNC.

    Radmin is one excellent package that supports audio and only costs 45$/license.  They allow a free 30 day trial.

    http://en.wikipedia.org/wiki/Comparison_of_remote_desktop_software 

    That wiki article gives a rundown on the various remote solutions, what services they support (such as audio), what protocol they use, if they are free or charge, etc.

    Anyone else using VNC or other remote control options such as these for wired mannequin control?
