Abstract
A system including a host terminal having a controller which is coupled to a plurality of bridge interfaces, with each bridge interface being coupled to a separate plurality of secondary terminals over an associated data link. Each bridge interface has a communications chip, like an RS-422 chip therein. The controller is able to communicate with any secondary terminal in the separate pluralities of secondary terminals via the associated bridge interface without having to rely on a transmit/receive control line from the controller to each of said communication chips. In another embodiment, the bridge interface is used as a repeater.
