DB9 RJ45 Console Rollover Cable USB RS232 to Cab Router for Cisco Huawei etc (RJ45 BLUE)

This cable is for updating DB9 to RJ45 cable, you can reference the following DB9-RJ45 cable information: The standard formerly known as RS-232 or RS232 became EIA-232 then TIA-232. Most of the world still calls it RS232 but many names are used. RS-232D or EIA-561 defines the pin assignments for using RS-232 with RJ45 connectors. For an RJ45 male connector, the one you'll find at both ends of a Cat6 cable, pin 1 is the left most pin when you look at the connector with the tab up and the cable going away from you. It's easier to buzz out a cable with the tab down, in which case pin 1 is on the right, thus leading to a lot of potential confusion. For the DB9 female connector pin 1 is the top right and pin 6 is the bottom right when you look at the connector with the cable going away from you and the side with five pins on top. At this point it's probably good to mention that you only need three lines to have a functional cable. You'll need RD, TD and ground. All the other lines are used by software to control data. The three critical lines are handled by hardware. But most of us don't write the software at both ends, so it may wait forever for a signal transition that will never happen.
