5.8 Connecting the matrix
Tip: For detailed information about connecting the matrix to user panels, interfaces and
other devices, see 4 Installing the
Eclipse HX-Delta .
The Eclipse HX-Delta matrix connects to devices such as the external computer that runs
the EHX configuration software, panels, interfaces, and other matrices through its rear-panel
hardware connectors, often called ports.
These connectors are housed in modular removable panels. Each panel is associated with a
corresponding front-panel interface or CPU card.
