Product Features
Technical Overview
The Digi One SP implements a single DB-9 serial port supporting RS-232 communication standards, paired with a 10/100 Mbps RJ-45 Ethernet port for network connectivity. The compact desktop enclosure measures 3.70" x 1.72" x 0.93" (93.98 x 43.69 x 23.62 mm) and weighs just 63.5 grams for flexible placement.
Power flexibility comes from the universal 110-220V AC input, eliminating the need for region-specific power adapters. The device operates with Digi's RealPort driver technology, which creates virtual COM ports for seamless integration with existing serial applications.
