Designed for professional network engineers, it supports most routers including Cisco and TP-Link, featuring nickel-plated, oxygen-free copper connectors and dual shielding to ensure interference-free, secure, and stable network device configuration.

## Description

COOSO rollover console cable helps you connect your PC to your Cisco device through the console port. These cables are the same ones that come with Cisco switches, firewalls, routers, wireless devices and more. It works with both new and old Cisco products. Most people use standard Windows hyper terminals or other terminal emulation software to access the Cisco IOS through the console port. If you have a new laptop, it may not have a 9-pin serial port, then you should purchase a USB console cable kit in this same category. Note: Many users recently don't set any issues, please use Google before setting up tutorials.
