Black Box serial adapter

The Modular Modem Eliminator connects any two data-communications products with similar or different interfaces. It functions in three ways: as an interface converter, as a modem eliminator, and as an elastic buffer. A handy switch lets you select the mode of operation. As an interface converter, the unit lets you connect DTE to DCE with different interfaces. It converts the physical and electrical difference between the two interfaces. As a modem eliminator, the unit eliminates the need for two synchronous modems. It allows you to connect two DTEs with similar or different interfaces. The converter provides clock, and performs handshaking of control signals, simulating modem operation. As an elastic buffer, the unit lets you connect two independently-clocked DCEs. It buffers data in both directions to overcome different clock phases and reduce data loss for different clock sources. The two DCEs may have similar or different interfaces. And the Modular Modem Eliminator runs at data rates up to 2.048 Mbps using internal or external clock. A complete system consists of the Modular Modem Eliminator and two interface modules of your choice.
