Model 7160 HD/SD/ASI/310 Protection DA MODULE OVERVIEW The 7160 Serial Digital Protection DA module is a fail-safe bypass protection switch for monitoring and switching critical SD and HD paths in broadcast and satellite applications. When a fault is detected in the Primary input, the switch will activate, causing the Secondary (backup) input to be switched to the module’s distributed outputs. The switch can operate in two modes; automatic or nonresetting.
Model 7160 HD/SD/ASI/310 Protection DA Black detection is performed on a pixel-by-pixel basis within the selected window, with user selectable Detect Level and Blk Frac adjustments. Pixels above the Detect Level are considered as being nonblack. Blk Frac sets the percentage of pixels which must be non-black. If Detect Level is set to 12 IRE and Blk Frac is set to 10% then the 7160 expects there to be pixel levels above 12 IRE for more than 10% of each frame.
Model 7160 HD/SD/ASI/310 Protection DA The Pri ASI Status indicator show what has been detected in the incoming DVB-ASI or SMPTE 310M stream. Possible indications are: • Good – The DVB-ASI or SMPTE 310M signal passes all tests (either Simple or Advanced) • No ASI – No DVB-ASI or SMPTE 310M signal has been detected • No Packets - All of the packets in the stream are null.
Model 7160 HD/SD/ASI/310 Protection DA Each of the signals is fed to identical detection circuits which evaluate multiple parameters and characteristics of the signal in order to arrive at a fault decision. Detection of TRS errors is done in a Receiver/Reclocker circuit which produces a reclocked serial output feeding a Deserializer circuit. The output of this section then feeds a Field Programmable Gate Array (FPGA) where the signals are vetted, or tested for configured parameters.

Model 7160 HD/SD/ASI/310 Protection DA APPLICATIONS Auto-Switched Trouble Slide Application In the example below, the main program feed is input to the 7160’s primary input. The secondary input is from a logo inserter and is a “Please stand by” graphic. In the event that the provider’s program feed is not present, the 7160 automatically switches to the secondary “Trouble slide” feed.
Model 7160 HD/SD/ASI/310 Protection DA Auto-Switched Upconversion Application The diagram below shows a typical use for the 7160 module, where it is used in conjunction with the 7900 Up/Down/Cross Converter module to form a fully-redundant, auto-switched conversion chain. The Primary input is backed up with a Secondary input from a video server. The 7160 Protection Switch can accept different types of signals on its two inputs.

Model 7160 HD/SD/ASI/310 Protection DA Status and Alarm Cabling In addition to full monitoring and access through the control system, the 7160 module provides contact closure status indications through the 15-pin D Control connector on the corresponding rear slot of the frame. These connections can drive an alarm system or other external monitoring devices, including LEDs. Two override GPI Inputs can also be accessed through the connector.
Model 7160 HD/SD/ASI/310 Protection DA MODULE CONFIGURATION AND CONTROL The configuration parameters for each Avenue module must be selected after installation. This can be done remotely using one of the Avenue remote control options or locally using the module front panel controls. Each module has a REMOTE/LOCAL switch on the front edge of the circuit board which must first be set to the desired control mode. The configuration parameter choices for the module will differ between Remote and Local modes.
