I know this is a bit of the topic I will ask any way.
I am installing a new firmware on my Sim2 C3X projector via a loptop with only USB ports no serial port .
How do I do this and what cable to I need.
I love All Meridian Gear.

Does the projector have a serial port? If yes, then you need to get a USB->Serial adaptor- many here are using one for the M software.

Just to make it clear, a USB->Serial converter is simply as said - it converts USB to serial. Just because they are often sold as a 'flying lead' it doesn't mean that they wont need a serial cable or adaptor in their own right. A number of time recently on a number of BB's I have seen people having problems with USB/Serial converters simply because they did not realise that they needed additional equipment in the chain. Often require a null model adaptor or cable is required - as is necessary with Meridian kit.
The null modem adaptor/cable has the tx and rx lines crosslinked - this allows DTE (Data Terminal Equipment such as PC) to DTE connection ie PC to PC rather than DTE to DCE (Data Communications Equipment such as a modem) ie PC to modem. Whether a piece of kit acts as DTE or DCE is down to how the connection is viewed by the manufacturer, but as a general rule, something that terminates a communication chain (ie PC, Meridian processor, maybe your projector) is a DTE and something that is part of a comms chain (ie modem) is a DCE. If you are trying to perform DTE to DTE comms, you will will require some form of null modem adaptor, be it a cable or adaptor box/dongle. A null modem adaptor is more than a 'gender bender'.

Thanks Ian. Is it possible if you can tell me exactly what I need to buy to do the job, any part numbers so I can drive to Radio Shack and buy the stuff off the shelve.

Meridian USA recommended the Keyspan USB to Serial converter to me and you can compare prices online at Froogle.
I used a Radio Shack null modem adapter, but I'm sure you can find one at your local "serious" electronics store.
