Eight serial ports on Ethernet
The Moxa NPort 5650I-8-DT connects eight RS-232/422/485 serial devices to a 10/100 Ethernet network. It is built for engineers who need to bring legacy PLCs, meters or barcode scanners onto IP infrastructure without rewriting software. The desktop enclosure includes 15 kV ESD protection on every serial signal and 2 kV isolation for industrial environments. Real COM, TCP server, TCP client and UDP socket modes cover most automation protocols.
Check power and cabling first
Verify that your site can supply 12 to 48 V DC through the terminal block or the 110 V AC adapter included in the package. Each of the eight ports uses a DB-9 male connector, so confirm that your serial cables match this pin-out before ordering. The unit auto-senses 10 or 100 Mbps Ethernet; ensure your switch port is set to auto-negotiation to avoid duplex mismatches. SNMP MIB-II is available for monitoring, but only if your management system supports it.
LCD panel and pull resistors simplify setup
The front LCD panel lets you assign a static IP address without a PC, reducing commissioning time on the factory floor. Built-in 1 kΩ and 150 kΩ pull high/low resistors plus a 120 Ω terminator are selectable per port, so you can balance RS-485 buses without external components. ADDC handles data-direction control automatically, removing the need for software timing adjustments in half-duplex applications. These integrated features replace external termination blocks and manual DIP-switch configuration.

Questions about this item
What serial interfaces and connectors does the NPort 5650I-8-DT provide out of the box?
The unit has eight DB-9 male ports that support RS-232, RS-422 and RS-485, so serial devices can be connected directly without extra adapters.
Which power input should I plan for when installing the NPort 5650I-8-DT?
It accepts 12–48 V DC through terminal blocks or a power jack, and a 110 V power supply is included for mains connection.
How does the 15 kV ESD rating protect my serial equipment in practice?
Every serial signal line withstands 15 kV electrostatic discharge, shielding connected devices from surges that can occur during handling or in industrial environments.
