Why it’s worth it
This cable keeps things simple, offering plug and play after a one time driver install according to the manufacturer. Triple shielding and tinned copper conductors aim to reduce interference on long runs, which helps when you are configuring network kit or steering a telescope controller at a distance. Note that driver availability can vary by operating system, so check compatibility before purchase.

It works well for console access to Cisco routers and switches, for interfacing with Celestron NexStar hand controllers, and for certain AV control hardware such as Extron and Crestron units. It’s a practical cable for network engineers, hobby astronomers and AV technicians.
