Model:SH-RJ45A

FTDI 社の FT232RL を使用した USB －シリアル（TTL）変換ケーブルでした。 USB 側に LED が付いており、接続、アクセス時に光ので分かりやすいです。 Cisco の VPN ルーターのコンソール接続用に買いました。 問題なく使えています。

Since this is not a cable you use everyday but only when you need to debug a switch firewall etc when you're in trouble this is the cable you need, well at least if your switch firewall has an rj45 serial port. Since this cable is in general used sporadic it also comes with good protections. Windows doesn't recognise the serial out of the box and you need to insist a little with windowsupdate. But then it works

It worked perfectly and replaced one that claimed it was a console cable but didn't work at all!

does what it is meant to do and looks well built.

Worked only once then hasn't worked again. Checked on Amazon and the product is no longer available, even though these items area used by computer techs everyday. Leads me to beleive they were ALL faulty, Not happy, lost allot of time over this issue now and productivity.
