This card is designed specifically to work seamlessly with the Aiphone AX intercom system on multimode or single-mode optical fibers. The card features 1 channel of 10-bit, high resolution video, 1 channel of 24-bit, digitally encoded audio and 2 channels of bi-directional contact closures. These contact closure channels can be individually configured as either normally open (NO) or normally closed (NC). The FT/FR-AiphoneAX1-SFP accepts PAL, SECAM, or NTSC formats. This product incorporates the industry standard Small Form Pluggable (SFP) optical device. This SFP gives you the option for either singlemode, multimode or CWDM wavelength selections by simply plugging in the appropriate SFP module. The versatility of this card 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 and eliminates the need for additional test equipment. SpectraView also includes a selectable on-board audio test signal generator with built-in local and remote loop- back functions. In addition, a video grey scale function is included to assist in monitor and system setup. If greater diagnostic capability is required, this product is also available with Meridian’s SpectraSmart Network management and diagnostic PC based system.
