Controlway is a redundant, high speed communication bus between Harmony rack controllers. The controller uses this bus to communicate with other controllers within a Harmony control unit. It provides a one-megabaud, peer-to-peer communication link that can support up to 32 devices. The Controlway interface is provided by a custom integrated circuit that links the controller to the Controlway. It has full DMA capabilities (allowing for quicker operation), and two independent, redundant channels. The redundant Controlway channels run through two paths on the MMU backplane circuit. The controller transmits and receives data over both channels simultaneously. By receiving data through two channels, the controller can check its integrity. In this way, Controlway minimizes the potential that a failure on a circuit board or backplane will cause loss of controller communication.

Buying equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to buy equipment aboard and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.

With video, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.
