Universal g code sender for arduino. Description USB to RS232 standard 36 inch serial adapter unit is compatible with most GPS and PDA devices including Garmin and Palm. Office equipment compatibility includes modems, printers, scanners, digital cameras and other USB office equipment.
The USB Plug and Play feature allows easy installation of the USB to RS232 serial adapter and requires no IRQ, DMA, or I/O port resources. With no IRQ, DMA, or I/O requirements, more devices can be attached to your system without the hassles of device and resource conflicts. The device is immediately recognized by your system; simply connect the adapter to your target device. This serial adapter is supported by Windows 10! These are light years easier to deal with than the typical (fake) Prolific chipset units. This particular one is especially nice. There’s no clunky box at all- the guts are hiding in the USB plug.
So it looks like a straight USB to 9-pin D. FTDI chip support pops up like magic in every Windows, Mac OS X, and Linux I’ve had a chance to use with it. Thank god there’s an alternative to the terrible Prolifics. Their drivers are awful and apparently most of the chips on the market now are cheap semi-functional counterfeits.
I can’t remember the last time it wasn’t a huge hassle getting a PL2303 to work right. If you’re using one of these, you’re likely sitting on the floor of a colo somewhere desperately trying to fix something important.
Do you have time to screw around with your adapter first? Works Great with Mac, but check your serial socket gender before ordering. Works GREAT with my Macbook Pro with OSX Yosemite. The trick is the FTDI chip inside the cable.
Don’t forget to DOWNLOAD and install the Mac driver, or you’ll think it doesn’t work. NOTE: This product (and most like it) has the wrong gender if you’re trying to control a Radio or Ham Transciever. Notice most people who buy this also buy the “mini DB9 Female to Female Gender changer? Dummy me I DIDN’t notice and had to make a special run to pick one up locally!
The two are sold together if you look at the bottom of the screen. 
Must be a popular combo for some reason;o) •.
