Ethernet Network to Serial RS232 RS422 RS485

  

The NetCom range of serial servers allow you to connect industrial machine and monitoring equipment to your network. They provide communication to RS232, RS422 and RS485 equipment over a 10/100Mbps NIC Ethernet network. The distance limitation of RS232 is overcome by installing  the NetCom close to the RS232 device.

The NetCom Serial Devices Servers are designed to remotely operate serial ports over networks. The network interface is 100Mbit/s Ethernet on all cable operated models. The transport is implemented via TCP/IP protocol. Therefore control is available via Ethernet, Intranet and Internet. The supplied driver software hides the network transfer from your applications. Software applications using standard COM ports need no change to operate via NetCom through the virtual serial ports.

These devices come with a steel case well suited for industrial environments.

NetCom supports high serial speeds up to 921 kbps. All serial ports operate in common RS-232 mode. The models NetCom 113, 413, 813 and 813RM also offer the industrial RS-422 and RS-485 configuration. In RS-485 mode the NetCom may use the Automatic Receive Transmit (ART) control logic to follow the RS-485 specifications for transmitting data. No special code is necessary to be implemented in your software applications.

The Pro versions have password protection and encrypted communication.

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)
NetCom 1613 RM PRO can control 16  RS232/422/485 devices located virtually anywhere (via NIC Ethernet or Internet)
