NetCom 111 is an industrial-strength network-based serial device server for connecting one RS232 device 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 111 can be configured over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serves as a transparent serial channel without platform and distance limitation.New: The serial connector is pin-compatible to Com1 on a PC, as DB9 male. The RS232 Null-Modem Adapter is no longer required.
The power consumption of NetCom 111 is very low, supply via Ethernet is available. See the option, read background information, or check an adapter.

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.
Raw data transfer over TCP/IP. Accepts multiple incoming connections.
Raw data transfer over TCP/IP. Connects to multiple hosts or devices waiting for incoming connections.
Special settings for user-defined modes.
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.
Connecting two NetCom used as virtual null modem cable.
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.
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
