【Important】Connection has been confirmed only with Cisco routers and switches; connection with products from other companies may not be possible. This is a set of an RS232C (male) USB serial cable (FTDI chip) and a console connection conversion adapter (for LAN cables). ※The console connection conversion adapter was devised through the experience of CCIE network engineers in field work, and we directly assemble and inspect it. Operation has been confirmed on Windows 7, 8, 10, and 11. The connected device is a Cisco Catalyst 2940 console port. If you prepare an 8-core straight LAN cable for this product, you will be able to connect to the console of Cisco routers and switches (e.g., Cisco 891FJ, Catalyst 3560, etc.). [Product Condition: New] ※The RS232C cable is connected to a PC during driver confirmation. ※The conversion adapter is connected to network devices during LAN cable confirmation. ※There are no packages or paper manuals. [Drivers and Installation Method] ※For Windows 10 and 11, if Windows Update has already been performed, the appropriate driver will be selected, so it will basically be automatically recognized by connecting the RS232C serial cable to the USB port. However, if it is not recognized, you may need to manually install the driver.
