Westermo Industrial ADSL router for replacement of leased lines

Supplier: Paqworks by Madison Technologies

New from Paqworks is the Westermo DR-250 Industrial ADSL2 Modem which can be used for local connectivity to serial devices and for the replacement of dedicated leased lines.

Price Guide: POA

The Westermo DR-250 Is based on the very latest ADSL2/2+ platform,supporting the fastest broadband speeds available. ADSL2 offers considerable performance benefits over standard ADSL, including improved range and data rate.The  Westermo DR-250 has an integral four port Ethernet switch and a 25 pin RS-232 serial interface for local connectivity.

Devices that support serial protocols such as Modbus RTU, DF1, DNP3, IEC870 etc can be easily connected to the DR-250 via the serial port. The Ethernet interfaces support Multicasting (IGMP), VLAN, SNMP, SNTP, FTP, as well as allt the standard TCP, UDP and DHCP protocols. The inbuilt
RS-232 port can be used to connect legacy serial based equipment such as PLC’s, RTU’s or IED’s. Alternatively the internal serial port can be used as a backup connection to the remote site when used in conjunction with a suitable Westermo Modem.

The Westermo DR-250 router has an integrated stateful inspection firewall and can support 20 IPSEC VPN (Virtual Private Network) terminations which can be secured using optional DES, 3DES, AES encryption and MD5 or SHA1 key exchange protocols. These features ensure that the remote sites can use the latest security technology to resist denial of service and hacking attacks. The VPN’s can be used as a way of increasing security and to create secure tunnels, running between sites. The VPNs can be used to interconnect sites effectively replacing the requirement for dedicated leased lines. A VPN tunnel can be established between any of the DR or MR series routers. Alternatively VPN’s can be created between the DR-250 and a third party router.

An optional license for 50 or 100 VPN terminations is also
available (up to a maximum of 200). The Westermo DR-250 can also be used for remote sites access, allowing the user to browse WEB pages, monitor / edit PLCs or access any device connected to the LAN. The DR-250 will allow devices on the LAN to send emails or connect to FTP servers.

Multiple routers can be used on the same LAN to provide redundancy. The routers use VRRP (Virtual Redundant Router Protocol) to allow a seamless changeover between primary and backup routers. For complex mesh network applications the DR-250 supports OSPF, BGP and RIP2.

The DR-250 can be supplied with a combination of UTMS 3G/HSDPA wireless card, and or PSTN/ISDN to backup the primary ADSL should there be an interruption in service.

The wide temperature range, 10–28 VDC supply and DIN rail mounting ensure that the DR-250 can be used in industrial applications without the need for modification or consideration of the environmental conditions.
