Anyone know where I can get a, preferrably cheap, RS232 to USB cable to access and unlock ISF modes on the 9G PRO-111FD?

You need a crossover 232 cable and a USB to 232 adapter. They are available at best buy, and I'll bet there are other sources as well. I think retail at BBY is close to $30 for the USB-232 adapter. There are likely cheaper options out there, but I'm not aware of any, maybe someone else will chime in.

That being said, I've not had good luck getting the USB-232 adapter to work well with the pioneers, I use a laptop dock with 232 out directly. But the adapters work well with many other 232 devices, and I don't know what computer you have, so who knows...

Actually, for the Pioneers, you need a Straight-Through configured Serial Cable (not Null-Modem / cross over), DB9 Female. If you had two Null Modem / Cross Over cables, you could connect them together (with the proper adapter) X + X equals =

As Chris posted, there are issues with many of the USB Serial Adapter unfortunately...

I've always used crossover cables on the pioneers. It depends on the source 232 that you're using though, whether you need that or not, so it will depend on what your computer is.

Chris, I'm not sure what adapter (perhaps changing from DTE to DCE) you are using but it's Pioneer's documentation:

All 2008 plasma display models use a “Straight” or “Pass-Through” Cable

Pioneer is expecting the other end to be DTE (standard for PC's)

But if the other end isn't, you just use a crossover cable. Not a big deal. In my case I have to use a crossover cable from my laptop's docking station.

I haven't tried specifically with the pioneed, but belkin's adapters have historically worked well for when connecting to most serial devices.

Here is the one we use from Monoprice, it works with XP/Vista without any problems:

The Keyspan adapters work just great as well. Datacolor was including the Keyspans for the Pioneers in their SpyderTV Pro 2007 and Colorfacts packages. I have switched the Keyspan between two laptops and have calibrated about 20 Pioneers with it without a single problem.

hi guys
the only Pioneers that require a cross over cable is the 1410 and the old 730HDI crt RPTV. All others are straight.
