Keep serial infrastructure reachable without adding complexity. Perle Systems IOLAN DG1 is designed to connect one DB9 device through RS-232, RS-422, or RS-485 while presenting it over 10/100/1000 Ethernet for remote administration and monitoring. That makes it a strong fit for teams that need stable access to equipment that cannot be replaced or reconfigured easily. This model is built for environments where console visibility matters. By preserving access to a single serial endpoint, it helps reduce truck rolls, shorten troubleshooting cycles, and keep remote sites manageable from a central operations team. The DB9 interface is a familiar choice for industrial gear, embedded systems, and network-adjacent hardware that still depends on serial control. For organizations standardizing on reliable infrastructure tools, the DG1 offers a focused design rather than unnecessary extras. It is a straightforward way to extend the life of essential equipment while keeping access paths consistent across distributed locations.
