Manufacturer Part #: AD-DB9M/RJ45
Modular adapters are perfect for network administrators because they reduce the cables that they have to carry. This modulator has a male DB-9 end and connects to a standard RJ-45 Ethernet cable. This is also a great way to extend your serial devices by using inexpensive RJ-45 cables.
This adapter features a unique design that allows you to connect the pin-out how you want it. This way an administrator can connect to servers, Cisco routers, or other serial devices while only carrying an RJ-45 cable and this adapter.
