Cabling your serial devices to a Digi product is now easier than ever with these new cable adapters. While many custom cabling solutions can leave you with a cable that is either too long or too short for your application, the Digi cable adapters are used with commercially available CAT 5 cable of any length. Simply plug standard CAT 5 cable into your Digi product, connect a cable adapter to the other end and plug the adapter into your device. The Digi TS DB-25M Modem Adapter is designed for DCE devices such as modems with DB-25 female ports. For a complete compatibility list please refer to the original manufacturer's web site.
