Now I don't know if this is so or not. The Skyspan I ended up buying was from an Apple store so that explains why the cost is so high. But it works a treat. --geoff Dave, yes you can but I was told that there were good serial converters & bad serial converters, some of them don’t allow good passage of all the signals.

Nope–no new circuit board for this mod.

Wow–it seems like you could find a USB-to-Serial converter for a lot less than $70 these days–but then again, I haven’t been looking for one…

Up till now I've been using a Skyspan serial to USB adapter. Works great and I haven't had any problems with it. It's just that I wish I'd known about your mod before I paid the $70 for the Skypan!! I have a couple of friends who're making the Ek box and I'll tell 'em about this before they get too far. Is there a new circuit board with this mod available? --geoff Jim, thanks for this.

It must means that you can connect it to a PC's USB port instead of a serial port. Since you're talking about a Palm device, this modification won't work for you. For improved battery life, I recommend you use a sealed lead-acid battery (sometimes called a gell cel. You can often get them surplus for not a lot of money. James,

Harris Sat, 01 Dec 2007 15:58:42 +0000 http://eksfiles.net/blog/?p=11#comment-4 Hi George, I wrestled with this same question before purchasing. I decided to go with the 5v version of the unit instead of the 3.3v (3V3) version, since the original circuit had a 7805 5V regulator in it (U1). There are also several styles of the 5V version. I got the "base" model, not the "AJ" (audio jack) or "PCB" version. I happened to order from Mouser (it's available elsewhere, too). The (complete) Mouser part number is: 626-DLP-TTL232R Keep looking up, Jimbo Hi George,

They have different specifications in the Vcc. Thank you. Hello David,

Do you know if for this modification Jimbo used the TTL-232R-3V3 or the TTL-232R?

They have different specifications in the Vcc.

Thank you.
