Know your gear

Using modular adapters with inexpensive silver satin or flat oval twisted pair wire has become a popular way to run client server applications. Needing to connect dumb terminals on the desktop back to a central patch panel or directly to a MUX via RS232, many network planners have implemented modular adapters as the most cost effective way to complete the connections.
Whether used in a wiring closet or throughout the office, color-coded modular adapters lend easy identification and differentiation to your cable plan. By color coding your connections, you cut down on troubleshooting time while taking full advantage of the benefits of this modular adapter approach. These modular adapters are not functional until they are assembled. There is not a universal way to assemble them, so contact your hardware manufacturer for details.

Rated 5 out of 5 by from fast delivery, easy to assemble Very easy to assemble with no tools required; clear pin out provided on product web page. Trying to remove an RJ45 connector from the RJ45 side of the adapter is a little difficult as the connection is quite secure and the long screws to secure the adpter to a male DB9 plug get in the way of trying to depress the tab to release the RJ45 connector (I have thick fingers), so it would be nicer if the screws weren't so long or if the RJ45 port/jack was rotated 90 degrees within the adapter to allow easier access to the RJ45 connector tab; however, the connection is strong and has no chance of becoming disconnected by accident, plus I imagine it will become easier to remove the connector with continued use as I get used to it.
