NetCOM 823RM WLAN

8 ports secure and wireless serial device server

 
NetCom 823RM WLAN is an industrial-strength network-based serial device server for connecting four RS232/422/485 device like CNC, PLC, weighting scale, scanner and other devices directly to a network running TCP/IP. This network may be based on 10/100Mbps Ethernet or Wireless LAN as of IEEE 802.11b/g.

NetCom 823RM WLAN provides completely secured communication for configuration and to the attached serial device.
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 823RM WLAN can be configured over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serves as a transparent serial channel without platform and distance limitation.

  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. Timeout functionality, maximum packet size and a configurable trigger string define the packets of incoming data to send over UDP.

  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
