The Greenleaf ViewComm II System

What is ViewComm?	“VCS” is a group of products that software engineers, field engineers, and others can use on a PC or laptop to visualize the content of an otherwise invisible stream of data packets flowing over an asynchronous serial communications link or Ethernet. VCS works its magic because it interacts directly with hardware. We do this with special serial drivers, and in the case of VCS Ethernet our magic is a bit different.

Is Viewcomm a piece of hardware test equipment?	No. It’s mostly software. All the tricky, cool stuff is software. For asynchronous work, we ship a special set of cables. We strongly recommmend VCS bundles which include your choice of about 9 serial cards.

So–it’s software but there’s also hardware?	VCS is 100% software except for the cables and bundled serial port hardware. If you’re testing Ethernet there’s zero hardware. Also zero if you’re spying on a serial port while a communications link is up on the port.. If you need to connect to some other device, you need our cable set. For async faster than 115,200 use a bundled serial card: 921,600. PCI or PCMCIA. RS-232 or 422/485. No extra gizmos.

What’s this about “bundled serial port” hardware? What’s wrong with the ports on my machine?	Nothing–if you have enough of them and they’re fast enough for you. Onboard and most add-on serial ports are limited to (a) 115,200 and (b) RS-232. If you need 422 or 485, you have to buy an adapter. Quatech and our developers collaborated on the drivers to assure you’re up and running in minutes. Bundled serial cards work at 921,600–matching the new HS (High Speed) models of VCS Async now shipping. They’re made by Quatech, a leader!
