Maintain access to legacy serial devices without tying technicians to the rack. Perle’s IOLAN DG1 DB25 device server bridges one DB25 serial connection to Ethernet, giving infrastructure teams a practical path to remote administration, monitoring, and control. Support for RS-232, RS-422, and RS-485 makes it suitable for mixed serial environments where one port must serve more than one protocol profile. The 10/100/1000 Ethernet interface provides the network side needed for modern management architectures, while the DB25 female console connection keeps integration straightforward for supported equipment. This is the kind of device server that earns its place in production: it reduces site visits, preserves access to older hardware, and helps extend the service life of serial-dependent systems that still matter to operations. For teams standardizing remote console access across distributed infrastructure, the DG1 format offers a focused, single-port design that is easy to deploy where only one serial endpoint needs to be brought onto the network. It is a precise fit for environments that value stable access, protocol flexibility, and minimal footprint.
