MDS RJ-to-DB-9/25 Cable & Adapter Information

The MDS series of versatile data switches provides a convenient means for connecting multiple RS-232 devices, collecting and polling data from remote sites and multiplexing data from multiple input sources. MDS ports can be individually configured in (3) distinct modes of operation:

· Any-port to Any-port

When ports are configured in the "Any-to-Any" mode, communication is allowed between connected devices, regardless of dissimilarities between baud rate or parity. Any-to-Any ports can be connected to any other port by issuing simple ASCII connect commands. All MDS ports can be configured for Any-to-Any operation, allowing matrix connectivity of up to 16 RS-232 devices. Multiple MDS units can also be connected to expand the number of connected ports.

· Buffer Mode

Individual MDS ports con be configured as "Buffer-Mode" ports which allow for the collection and storage of data received from connected devices. Collected data can be retrieved by entering simple ASCII commands to poll the buffered data. The MDS contains a dynamically allocated battery-backed buffer which will safely store collected data until polled.

· Mux Mode

The MDS also allows selected ports to operate in a data multiplexing or "Mux Mode". The Mux Mode allows data from several sources to be directed to a common port. Data can be collected from connected devices and sent to a common host PC. The MDS will also stamp a port ID from each incoming data string to identify it's port of origin.
