NetCom 211 is an industrial-strength network-based serial device server for connecting two RS232 devices like CNC, PLC, weighting scale, scanner and other devices directly to the 10/100Mbps Ethernet network running TCP/IP.
In addition to allowing serial devices to get networked, any host (PC Server or Workstation) without network access can also access remote serial device via adding NetCom devices to the existing serial port. NetCom 211 can be configured over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serves as a transparent serial channel without platform and distance limitation. The power consumption of NetCom 211 is very low, supply via Ethernet is available. See the option, read background information, or check an adapter.

| Operating Modes |
Driver mode |
VScom Driver for Windows NT 4.0, 2000 up to 7, Server 2000 up to 2008 R2, both x86 and x64 Editions.
The Driver creates a virtual Com port, using Vscom NetCom protocol. |
TCP Raw Server |
Raw data transfer over TCP/IP. Accepts multiple incoming connections. |
TCP Raw Client |
Raw data transfer over TCP/IP. Connects to multiple hosts or devices waiting for incoming connections. |
TCP Advanced Settings |
Special settings for user-defined modes |
UDP Mode |
Raw data transfer by UDP. The NetCom is client and server at the same time. With the timeout functionality and a configurable trigger string it can make defined UDP packets of incoming data. |
Null Modem Tunnel |
Connecting two NetCom used as virtual null modem cable. |
IP Modem |
The serial port emulates a standard modem. Operates by AT-commands, and dials to IP-Addresses instead of phone numbers.
Windows "INF"-Driver provided for installation. |
Print Server |
The NetCom accepts print jobs, and spools them to the attached serial printer. Operates as of RFC1197, similar to the line printer daemon in Unix-systems |
