LINK ELECTRONICS LEI-515

The LEI-515 is designed to monitor two serial component digital signals and automatically switch to a backup digital source. In the event of a failure of the number one digital signal the LEI-515 will switch to an auxiliary signal. A captive-screw terminal sub-module is provided for "audio-followvideo" capability or status mode, which is switched internally.

A three-terminal dry-contact connector offers normally-closed and normally open contacts to control peripheral gear. The rugged and compact LEI-515 can mount in a one 1RU frame that holds up to three "500 Series" or "700 Series" units. Both component (270MB/s) and composite (143MB/s) digital video formats are supported.

The input receiver device monitors the incoming signal level and produces a DC voltage proportional to the amount of gain and equalization necessary to recover and re-shape the signal. This DC voltage is compared to a front panel userset threshold voltage. If the automatic gain/EQ voltage exceeds the threshold voltage, the LEI-515 will switch to its auxiliary input.

This "sensitivity" adjustment gives the LEI-515 the ability to select it's auxiliary input even before data errors are visible in the primary input. Front panel switches allow you to override the automatic change-over function and choose either video source. Dual front panel "status" LEDs indicate the presence or absence of both Primary and Auxiliary video inputs. Primary/auxiliary switching is accomplished by an active 2:1 multiplexer. This allows the user to take advantage of the automatic gain and equalization capabilities of the input receiver. However, a 75 O matched-impedance relay is also incorporated to allow the input signal to pass through if power is lost to the LEI-515. Engineered with the user in mind, the LEI-515 serves an important role in complete digital system reliability. Backed by Link's standard 10-year warranty, the LEI-515 will provide years of errorfree service.
