Bring serial equipment into your network management workflow without replacing what still works. The Perle Systems IOLAN SDG2 device server provides two RJ45 serial ports with RS-232/422/485 support and 10/100/1000 Ethernet connectivity, giving administrators a practical way to reach legacy devices over IP. This model is built for environments that need more than a single console connection but do not require a large chassis. Two serial ports make it a strong fit for paired devices, compact control rooms, and distributed sites where remote access must be reliable and easy to standardize. By moving serial management onto the network, teams can reduce truck rolls, respond faster to faults, and keep essential infrastructure accessible from a central location. The SDG2 is a focused choice for organizations that value precise control over serial endpoints. It supports mixed serial signaling, making it suitable for a range of legacy hardware and operational equipment. For enterprise teams balancing uptime, access, and cost, it delivers the right amount of capacity without unnecessary complexity.
