    Vista Com Port Setup

    This is a video of how to configure your comport so as you can select what ever number port you want to use with your null modem cable for flashing your boxes

    you have to choose between comport 1 - 4 so if your pc says that they are taken just select com 1 or the other numbers and say yes to whatever else comes up you will get a warning just keep going and you will be sorted

    To Assign A USB Port Using Vista:

    Although technically Vista does call the system "Computer" whereas XP refers to it as "My Computer"

    START
    Right Click "COMPUTER"
    Choose "MANAGE"
    In the resulting window, click on "DEVICE MANAGER"
    In the right hand pane, click on the little plus sign beside "PORTS" in the right hand pane.
    Right click on the USB Adapter (Should be something like “USB Serial Port COM # or "Prolific USB-to-Serial Comm. Port (COM#) or “Communications Port” (COM #) )
    Choose "PROPERTIES"
    Click on "PORT SETTINGS" TAB
    Click on "ADVANCED"
    Then you will see the COM Port Number Box. You should be able to change it there using the drop down box.
    Try to set it to COM2
    also change the baud rate to 115,200 from the default setting of 9600
    Restart Windows (If necessary but normally not required)

    NULL MODEM CABLES

    These are the cables you need to flash the REPAIR firmware.

    Try to make sure you are using a standard desktop pc with a 9 pin com port built in (no usb adapters), preferably running XP, and that the cable is a 9 pin serial CROSSOVER cable , known as a null modem cable, with 9 pin D plugs on both ends, as shown below

    Also ensure you are using the correct bin files for the model of spiderbox you are fixing, each model has its own files

    If you have a computer or a laptop with a 9 pin serial com port which is male on the back all you will need is this cable, bear in mind modern pc towers , desktops and laptops DO NOT HAVE the 9 pin serial com port required, do not mistake the 15 pin blue VGA port for a com port, its a video port for a monitor, NOT a com port

    Female to Female Serial Null Modem Cable which looks like the picture,

    Heres the NULL MODEM CABLE Code L71BT from m*pl*ns

    they are a lot cheaper on @uct1on sites

    they are also known as CROSSOVER cables due to the fact that pins 2 and 3 are "crossed over" when connected

    Simple Null Modem Cable

    pin 2 is wired to pin 3 (Rx to Tx)
    pin 3 is wired to pin 2 (Tx to Rx)
    pin 5 is wired to pin 5 (Ground)

    only 3 wires are needed so its very easy to make your own bespoke lead

    if you need the one with handshaking then look at the pinouts on here

    Code:
    _http://digital.ni.com/public.nsf/allkb/1EE0DD8AF67922FA86256F720071DECF

    Null Modem Cable with Handshaking


    pin 2 is wired to pin 3 (Rx to Tx)
    pin 3 is wired to pin 2 (Tx to Rx)
    pin 5 is wired to pin 5 (Ground)
    pin 7 is wired to pin 8 (RTS to CTS)
    pin 8 is wired to pin 7 (CTS to RTS)


    an RS232 cable is incorrect as its STRAIGHT WIRED and is usually male to female plug and socket , it can be used to extend a null modem cable however

    read this thread for hints and links about using the correct tools and leads and windows

    http://www.satpimps.co.uk/showthread...king-up-a-lot-!

    ALWAYS USE A DESKTOP OR TOWER PC

    ALWAYS USE A NULL MODEM CABLE ON ITS OWN

    NEVER USE A USB ADAPTER

    ALWAYS USE XP
