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. Please Note: Picture shows this adapter before assembly; this modular adapter will need to be assembled so that it is functional. There is not a universal way to assemble them, so please contact us for details. We'll be happy to assemble any adapter (for a nominal labor charge) to fit your application so that they are ready to use upon arrival.
