ST/SR-1W1C, module in the DigiSlim product family incorporates an all-digital encoding technology that transmits one real-time, simplex 10-bit composite video channel and one contact closure. Convenient 3-pin terminal block is used for easy connection of the contact interface. Status indicators provide visual indication of the operational status of the contact. NTSC, PAL and SECAM video formats are all seamlessly supported. These single fiber, laser based system is available in both, multi-mode and single-mode modules. The versatility of the DigiSlim series is enhanced by SpectraView, an On-screen video diagnostic/setup firmware system and SpectraSmart, an optional PC based network diagnostic system. SpectraView monitors the integrity of the video signal and the fiber link. A break in the fiber path will cause a loss of fiber alarm to be displayed on an associated monitor while loss of video sync will generate a loss of sync alarm on the monitor. SpectraView is easy to use, always active and eliminates the need for additional test equipment. SpectraView also includes a selectable on-board contact closure test signal generator. In addition a video grey scale function is included to assist in monitor and system setup. If greater diagnostic capability is required, the DigiSlim series is also available with Meridian’s SpectraSmart network management and diagnostic PC based system.
