1 Port RS-232 Serial to IP Ethernet Device Server - DIN Rail Mountable
StarTech ID: NETRS232
The NETRS232 Serial Device Server lets you remotely access and manage an RS232 serial device over a local or
wide area network (LAN/WAN), giving you a simple and cost-effective serial-over-IP control solution.
For installation flexibility across a variety of locations or environments, you can power the serial device server using
either a 12V DC power adapter (included) or through the integrated 10~30V DC terminal block. Plus, the device
server is DIN rail mountable for out-of-the-way installations. To help ensure seamless performance and prevent
possible damage to the server and connected devices, the serial device server offers 15KV ESD (Electrostatic
Discharge) protection.
This highly-customizable device server is easy to configure to suit your application, with versatile browser-based or
Virtual Com port software configuration and integrates support for VCOM, TCP Server/Client, UDP, HTTP, DHCP,
ICMP(PING), Static IP, and ARP protocols, while supporting baud rates up to 230.4 Kbps and is compliant with
IEEE 802.3, IEEE 802.3u standards.
Backed by a 2-year StarTech.com warranty and free lifetime technical support.
