Cabling your serial devices to a Digi product is now easier than ever with Digi's 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. Digi Etherlite DB-25M Modem Adapter is one of many Ethernet Cables available through Office Depot. Made by Digi.
