Port Modes
The MDS offers three port operation modes; the Any-to-Any
Mode, the Buffer Mode, and the Mux Mode. The MDS Port
Modes function as follows:
·
Any-to-Any Mode: Allows communication between
connected devices. Any-to-Any Ports can be connected to
other Any-to-Any Ports by accessing the Command Mode
and issuing ASCII commands. The Any-to-Any Mode is
available to all MDS ports.
·
Buffer Mode: Allows collection and storage of data
received from connected devices. Collected data can be
retrieved by accessing the Command Mode from an Any-to-
Any Port, and issuing the Read Buffer (/R) Command. The
Buffer Mode is not available to Port 1.
·
Mux Mode: Allows data from several sources to be
multiplexed to a common port. During port configuration,
Mux Input Ports are assigned to a common Mux Output Port.
Data can then be collected from connected devices and sent
to a device connected to the Mux Output Port. The Mux
Mode is not available to Port 1.
MDS Port Modes are discussed in detail in Section 6.

Command Availability
The "Commands" field in the Port Configuration menu allows the
user to specify which MDS commands will be available to each
port. The user can either select "All" commands or only "Basic"
commands. The "All" option is normally selected for
administrator ports, and allows access to all MDS commands.
The "Basic" option is normally selected for user ports, and
allows limited access to MDS commands. Section 8.3
summarizes "All" and "Basic" commands.
In the default state, Port 1 is the only port with access to "All"
MDS commands. When ports are configured, at least one port
should be granted access to "All" MDS commands.
