About this item
The DIEWU 8-port RS232 RS485 RS422 to Ethernet serial device server puts eight serial devices on a TCP/IP network. That makes it useful for PLCs, meters, POS hardware and lab instruments that still use serial ports. It's listed new at $165.44.
What should I confirm on an 8-port serial to Ethernet converter?
The title lists the three serial standards, but not the connector type, power input or configuration method. Those details decide whether it fits your setup.
- Connectors: check whether the ports are DB9, RJ45 or terminal blocks, and how they map to RS232, RS485 and RS422.
- Power: confirm the input voltage and whether a power adapter is included.
- Setup: look for how it's configured, such as a web page or a utility.
- Mounting: check the photos for rack, DIN rail or desktop mounting.
A practical way to network older serial equipment without replacing it.
