It is built for the situation where an ordinary USB cable simply stops working: the distance between your control computer and the camera or controller on the telescope. Signal boosting electronics are built into the cable itself, so it maintains USB 3.2 Gen 1 (5 Gbps) throughput across the full 20 metres rather than degrading part-way along it.\u003c\/p\u003e\n\u003cp\u003eAt 20 m this is the longest cable in the Pegasus Astro active range, and it supersedes the earlier 15 m version.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis is a good match if you:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRun a permanent or semi-permanent observatory\u003c\/strong\u003e where the imaging PC lives indoors and the telescope sits on a pier some distance away.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImage remotely from a warm room\u003c\/strong\u003e and need a single reliable data link rather than a chain of couplers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse a USB Type-B device on the mount\u003c\/strong\u003e — a cooled CMOS camera, a powerbox, or a USB hub — and need it to enumerate reliably at the far end of a long run.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive signal boosting:\u003c\/strong\u003e built-in repeater electronics regenerate the USB signal, which is what allows a 20 m run to work where a passive cable cannot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB 3.2 Gen 1 rated:\u003c\/strong\u003e 5 Gbps SuperSpeed throughput, sufficient for high-frame-rate and large-sensor camera downloads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType-A to Type-B termination:\u003c\/strong\u003e the standard pairing for astronomy cameras, powerboxes and powered hubs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirectional by design:\u003c\/strong\u003e as an active cable it has a defined host end and device end, and must be oriented correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 metre length:\u003c\/strong\u003e the longest active option Pegasus Astro offers, replacing the discontinued 15 m variant.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLinking an indoor imaging PC to a pier-mounted camera or powerbox in an observatory.\u003c\/li\u003e\n\u003cli\u003eWarm-room remote imaging where the run exceeds the roughly 5 m limit of passive USB 3.0.\u003c\/li\u003e\n\u003cli\u003eFeeding a powered USB hub at the telescope from a single long upstream cable, consolidating multiple device connections into one run.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector pairing:\u003c\/strong\u003e USB Type-A at the host end, USB Type-B at the device end.

There are no drivers and no configuration. The only thing to get right is the direction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy use an active cable instead of joining two passive cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePassive USB 3.0 becomes unreliable past roughly 5 m, and joining cables compounds the problem rather than solving it. An active cable regenerates the signal internally, which is why it holds up at 20 m.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it slow my camera down?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. It is rated for USB 3.2 Gen 1 at 5 Gbps, the same as a short USB 3.0 cable, so download times are unaffected.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it with a USB 2.0 device?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
