RJ45 to DB9 male modular adapter is a cost-effective solution to connect serial printers, terminals, modems, POS devices and other serial equipment. Using modular adapters with inexpensive silver satin or flat oval twisted pair wire has become a standard 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 RS-232, 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 reduce troubleshooting time while taking full advantage of the benefits of this modular adapter approach.
