Disklavier

i have a disklavier mark iv and the prc-100 will not connect to the mark iv. controller still has interface, no connect. it is running version 2 of the software and would like to upgrade. i was told i have to upgrade to 3 then thru an internet connection i can upgrade to 4. problem is the mark iv is not on line, is the prc-100 the only way to get the mark iv on line. second question is can i up grade the software on the mark iv with out it being online, and does the upgraded software give me any more control over getting the mark iv online with out a prc-100. lastly, do you know where i could rent a prc-100 for an hour

If you have the original, YAMAHA labelled, card, it may be worth trying another card (Ambicom, etc, quite cheap from Amazon). The original cards were quite low in power. If that doesn't work, you may have a problem with the CF card interface, either on the PRC-100 or on the motherboard of the I/O unit on the piano. If it is on the motherboard, you may get away with using a PCMCIA - CF card adaptor ( not tried that myself, but I have heard that it works). If the problem is with the PRC-100, you can update the piano to Version 3 via CD and then go to version 4.xx via the internet. You'll get iPhone/iPad/iPod connectivity via your wireless broadband router. This will allow you to use a free app to control most basic function. Replacing the motherboard or PRC-100 will be seriously expensive, so, unless you're doing really complex stuff, I would try one of the previous options.

While you're under the piano, it's also worth having a look at the power supply - an oblong black box. There should be 4 LEDs in a row - one blinking and 3 on permanently.

There are a number of CF wireless cards available on Amazon or Ebay which might work (usually GBP12.00-18.00, last time I looked)

If you go into the Qtopia menu on the bottom left - and click on Settings, Network - you should be able to see Services. You can try pairing your device with a 802.11b network (say your own wireless router, or guest network). You can manually change the ESS-ID to either your guest network or your Piano's network's name (My Piano is DKV221XXX). If your wireless card is working, when you click on the Current tab - you should see a connection along with Signal and Quality % bars. If not, your wireless card may be bad.

If you're lucky you can find a working used one for around $10-25. I figured that there must have been a number of equivalent units that used the same chipset during that time frame, so I started searching to see if there were any 802.11b cards that were compatible with the Sharp Zaurus SL-5500 (essentially our PRC-100 is a rebadged one). I found that the Ambicom ises a Prism 2.5 chipset - so I searched for compatible device lists...and found that the Dlink DCF 660W was on the list. Bought one off of eBay...and just confirmed that it works without any tinkering! My PRC-100 is now as good as new.
