NetCom series is an industrial-strength network-based serial
communication device server for
connecting RS232/422/485 devices like CNC, PLC, weighting scale, scanner and
other devices directly to the 10/100Mbps NIC Ethernet network running TCP/IP.
In addition to allowing serial RS232/422 communication
devices to get NIC Ethernet 10BaseT/100BaseTx networked, any host (PC Server or
Workstation) without network access can also access remote serial communication
device via
adding NetCom devices to the existing serial communication
port. NetCom can be configured
over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serve as a
transparent serial channel without platform and distance limitation.
|
|
|
Driver mode
|
|
VScom Driver for Windows NT 4.0, 2000, XP and 2003,
Vista.
Driver Mode creates virtual Com port.
|
| |
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
|
|
|
|
 | NetCom 111 can control RS232 devices located virtually anywhere (via
NIC Ethernet
or Internet)
| NetCom 113 can control RS232/422/485 devices located virtually anywhere (via
NIC Ethernet
or Internet) |
| NetCom 211, 411 & 811 can control 2/4 or 8 RS232 devices located virtually anywhere (via
NIC Ethernet
or Internet) |
| NetCom 413 & 813 can control 4 or 8 RS232/422/485 devices located virtually anywhere (via
NIC Ethernet
or Internet) |
| LAN interface10BaseT/100BaseTx NIC Ethernet |
|
| Driver 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
| Support TCP/IP, Telnet, DHCP, ICMP, HTTP, SNMP, DNS
| Supports ART (Automatic Receive Transmit control)
| RS232/422/485 communication
interface selectable by Switches |
| Configuration utility automatically finds NetCom devices in
the network |
| Automatic mode switching between Driver and TCP RAW mode.
With TCP Advanced settings it is possible to configure the NetCom for using
it in multiple modes, so it decides automatically which mode should be used. |
| Configuration over Driver Panels, NetCom Manager, WEB
Browser, serial console, Telnet, SNMP |
| Domain Name Server support |
| Serial Interface configurable with external switch |
| Special precautions for Firewall environments |
| Firmware update over WEB Browser, Telnet, ComPort |
| LEDs for Power, Tx, Rx, LAN Link, LAN Speed |
| 3 year warranty |
