Item code: NetCom-Plus-813-POE

The NetCom+ 813 is an industrial-strength network-based serial device servers for connecting eight RS232 devices (or RS485 communication lines) like CNC, PLC, weighting scale, scanner and others directly to a network running TCP/IP. The driver for Windows operating system installs Virtual Com Ports. The network is Gigabit Ethernet or optionally wireless by WLAN 802.11b/g/n, another option is Power over Ethernet. The NetCom+ Servers use a state-of-the art RISC processor for low power and cost effective design. Power supply is via 12V DC, or optionally via Ethernet cable with POE IEEE 802.3af. The USB 2.0 port supports WLAN, and additional serial ports by expansion modules.

NetCom+ can be configured over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serves as a transparent serial channel without platform and distance limitation. As modern devices the NetCom+ provide encryption for all communication.


  • Controls 8 RS232/422/485 devices located virtually anywhere via Ethernet, WLAN or Internet
  • Easy selection of RS232, RS422 or RS485 by single DIP switch or individually by software
  • Port expansion over USB A connector
  • LAN 1000/100/10 Ethernet auto-detect
  • Supply via Power over Ethernet 802.3af
  • NetCom Manager automatically finds NetCom+ devices in the network
  • Configuration over Driver Panels, serial Port, Telnet, WEB Browser, SNMP
  • Automatic mode switching between Driver and Raw Mode
  • Supports TCP/IP, UDP, Telnet, DHCP, ICMP, HTTP, SNMP V1/2c/3, DNS, PPP, openVPN
  • SSL/AES-256 encryption on Ethernet, WLAN and Internet
  • Optional: Wireless network IEEE 802.11b/g/n
  • Optional: 3G/4G Modem for mobile networks
