The NetCom+ 811 DIO is an industrial-strength network-based serial device servers for connecting eight RS232 devices 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.
The 8 Digital-Input and 8 Digital-Output signals operate via known the protocol Modbus/TCP.

The NetCom+ 811 DIO Server uses a state-of-the art RISC processor for low power and cost effective design. Power supply is via DC adapter, or via Ethernet cable with POE IEEE 802.3af.
The serial ports enable data rates of up to 500kbps, including every non-standard bitrate. See the FAQ.

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. Modbus/TCP standard controls Digital-I/O function.
As modern devices the NetCom+ provide encryption for all communication.

Special Features
Installation For easy installation the configuration utility NetCom Manager automatically finds NetCom+ devices in the network
Operating mode Automatic mode switching between Driver and TCP RAW Server mode.
PPP Access Dial-In to a modem attached to a serial port using Point to Point Protocol. TCP/IP is transported over the serial line, allowing access to configuration and the serial ports, even without Ethernet.
Configuration Configuration over Driver Panels, NetCom Manager, WEB Browser, serial console, Telnet, SNMP
Firewall Special precautions for Firewall environments
Firmware Firmware update over WEB Browser
LEDs LEDs for Power, Ready, serial Tx, Rx, Ethernet Link, Speed
Password access Every capabilities of configuration use the same password including SNMP V3
Secure communication OpenVPN™ SSL tunnel provides security on Ethernet and Internet. The tunnel protects configuration and serial data, especially convenient to use across the Internet. OpenVPN software is available for many systems, including Windows, Linux and Mac OS. Strong encryption by AES up to 256 bit keys.
