USB Serial Adapters

We just purchased 2 more Catalyst servers that included two diffferent types of USB-Serial adapters, pictured here: www.fxproductionservices.com/forum/usbserial.jpg

I know the keyspan (pictured left) is for RS232, so is the VSCom adapter (pictured right) for RS422?
Went to the website provided on the VSCom box which didn't help out either. I was going to try and poke around on CatVX, but it seems the site is down.

Thanks!
