The Meridian Technologies DR-1A1C2K/2K-2 DigiFlex Laser-Based Multimode Receiver incorporates digital encoding technology. This fiber optic module receives one unidirectional 24-bit audio, one unidirectional contact closure, and two bi-directional RS-485 data channels over a multimode fiber.
It incorporates plug-in personality signal cards to easily configure a wide variety of module types. The functionality of this DT/DR-1A1C2K/2K Series Receiver is enhanced by its compatibility with Meridian’s PC-based SpectraSmart Network Management & Diagnostic Software system. SpectraSmart supervises the operating parameters of the transmission system such as the status on video levels, sync, digital carrier detect, voltages, temperatures, optical levels, etc.
The receiver is available with rack mount cards and modules that can be installed in Meridian’s card chassis, desk chaises, and 19” racking frames (sold separately). This system can be configured in either star (module to rack) or trunking (rack to rack) configurations. It can also be made a standalone system by using the SR-1000/s 2-slot desk / wall mount chassis (87 to 264VAC; sold separately).
