## Overview

The COOSO RJ45 to RS232 DB9 serial console cable is a 1-meter Cat5 Ethernet cable designed for professional network engineers to connect PCs to routers and switches via serial ports. Featuring bi-directional data transmission, dual shielding for EMI/RFI protection, and a secure screw-lock design, it ensures reliable, interference-free communication compatible with Cisco, TP-Link, and most major network devices.

## 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.
