ST/SR- AiphoneAX1-x, card is designed specifically to work seamlessly with the Aiphone AX intercom system on one multi-mode or single-mode optical fiber. 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. 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 loopback 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. This product is available as a rack mount card that can be installed in any of Meridian’s desk chassis or in 19-inch racking frames. This system can be transformed in to a standalone module by utilizing an SR-500 (standard configuration) or an SR-1000 subrack frames.
