RJ-45 to DB-25 cable adapters can be purchased from Digi. These adapters consist of a Digi 10-pin RJ-45 plug connected through a two- or four-foot cable to a DTE-configured DB-25 male connector. You can use DB-25 modem cables with the adapters for longer cable runs. Because these adapters use the standard Digi 10-pin RJ-45 plug and DB-25 connector configurations they provide full modem support (Ring Indicator and Data Carrier Detect are available only on 10-pin RJ-45 connectors).Primary InformationNetwork Cable Type : Serial cable Cable Technology : N/A Left Connector Gender : Male Right Connector Gender : Male Left Connector Type : RJ-45 Right Connector Type : 25 pin D-Sub (DB-25) Dimensions&MiscellaneousLength : 4 feet UNSPSC CodeUNSPSC Code : 26121620
