StarTech Serial Device Server, 4 Ports, 5V DC Nominal Supply Voltage - I43-SERIAL-ETHERNET

This serial device server connects legacy serial equipment to Ethernet networks, enabling remote access and control of RS232 devices from standard IP infrastructures. Designed for industrial and automation environments, it accepts multiple physical serial interfaces and operates within common ambient temperature ranges to support continuous system integration.

Features and Benefits:

• Four serial ports enable simultaneous multi-device connectivity
• Supports up to 921.6 kbps for high-speed serial communications
• Accepts DB9, RJ45 and 2‑wire Terminal Block connections
• Powered from a 5V DC supply for low-voltage installations
• Compliant with 10BASE-TX and 100BASE-TX Ethernet standards
• Meets EIA/TIA-232 signalling for RS232 equipment interoperability

Applications

• Suitable for remote monitoring of factory PLCs via Ethernet
• Ideal for serial instrument integration in test benches
• Used with legacy RS232 HMIs to provide network access
• Can be used for connecting serial sensors to SCADA systems
• Used for serial console access to networked control units

Which operating systems are supported for management utilities?

Management tools are compatible with Windows 8 for configuration and host connectivity.

How does it accommodate different connector types on site?

It provides a mix of DB9 and RJ45 ports Plus a two‑wire Terminal Block to match diverse cabling and device interfaces.

What temperature range can it operate within for plant‑floor deployment?

It functions reliably from 0 °C up to 60 °C, suitable for typical indoor industrial environments.

Which Ethernet speeds can be used for serial‑over‑IP transmission?

It operates on both 10BASE-TX and 100BASE-TX links to support varied network bandwidths.
