The Cobalt Digital 9940-ACO is an advanced 3G/HD/SD-SDI multi-input intelligent auto-changeover switch. It comes with an optional trouble slate inserter, offering manual input selection. When the input signal is lost, it can automatically switch to alternate inputs. It also conducts intelligent assessments of video quality events like black/frozen frames or audio silence. Additionally, it can detect the absence or presence of closed captioning for CEA 608/708 and line 21 SD closed captioning. For each video quality or closed-captioning event, the status can be independently propagated through GPO, automated alert emails, input routing changes, or user - configured presets. You can upload a custom trouble slate graphic to the card, which will be inserted into the active video if a video quality event error occurs. Two discrete character burn strings can be added to the output video, either as static text or only when there's a loss of signal (LOS). Standard test patterns can be inserted as LOS markers, and a moving - box insertion provides a dynamic raster confidence check even for static input images. The switch can receive and prioritize timecode from SMPTE embedded or audio LTC sources, then output and burn it into the output video. It allows you to save custom settings and easily revert to factory defaults. Layered presets let you make targeted changes without affecting other processing settings. You can control and monitor it locally or via an Ethernet network using the full user Dashboard or a remote - control panel. GPIO enables direct input routing control and status monitoring. Key features include multi - input with manual or intelligent auto - changeover failover, intelligent failover based on various conditions, video quality and closed - captioning detection, moving - box insertion for confidence checks, optional trouble slate import, dual independent burn - in text, advanced timecode processing, frame sync with format conversion, full audio crosspoint with delay control, remote control, hot - swappability, and a five - year warranty. Technical specifications cover video input/outputs, SDI formats, cable lengths, return loss, jitter, latency, input selection, power, timecode insertion, text burn - in, audio output, frame reference input, GPIO, and the warranty.

Using the Cobalt Digital 9940 - ACO is easy. First, connect your video and audio sources to the appropriate input ports. You can manually select the input you want, or set it to auto - changeover mode. In this mode, if the main input signal is lost, it will automatically switch to an alternate input. For video quality monitoring, set the thresholds for black/frozen frames and audio silence according to your needs. You can also configure it to send alerts via email or trigger other actions when these events occur. When it comes to closed - captioning, the switch can detect its presence or absence. Upload a trouble slate graphic if you want it to appear when there's an input error. You can insert text strings on the output video, which is useful for identification or providing information. The timecode function can receive and output timecode in different formats. Just select the source and the output format you prefer. To save your custom settings, use the preset save feature. If you need to go back to the factory settings, there's a one - button option for that. When using the remote control, make sure your device is connected to the same Ethernet network. For maintenance, keep the device in a clean and dry environment. Check the connections regularly to ensure they are secure. If you encounter any problems, refer to the user manual or contact customer support. Remember, this device comes with a five - year warranty, so you can have peace of mind while using it.
