Westermo MR-200 - Manual (Page 9)

9 6615-2202
Description
The MR-200 router is an GPRS router designed to be compatible with the current and
future requirements of remote telemetry and industrial control systems applications. The
unit has an integral Ethernet port and a 25 pin RS-232 serial interface for local connec-
tivity.
The Ethernet interface supports Multicasting (IGMP), VLAN, SNMP, SNTP, FTP, SNMP as
well as all the standard TCP, UDP and DHCP protocols.
The inbuilt RS-232 port can be used to connect legacy serial based equipment such as
PLCs, RTUs or IEDs. Alternatively the internal serial port can be used as a backup con-
nection to the remote site when used in conjunction with a suitable Westermo Modem.
The MR-200 router has an integrated stateful inspection firewall and can support 5
IPSEC VPN (Virtual Private Network) terminations which can be secured using optional
3DES, AES, SSL, SSH encryption, and MD5, SHA1 key exchange protocols. These features
ensure that the remote sites can use the latest security technology to resist denial of
service attacks and hacking. 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 the
sites effectively replacing the requirement for dedicated leased lines. The VPN tunnels can
be terminated on either another MR-200 ADSL router or on a Westermo DR-200 ADSL
router. An optional license for 50 VPN terminations is also available.
The MR-200 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 MR-200 will
allow devices connected on the LAN side to send emails or connect to FTP servers for
transferring files.
The MR-200 supports VRRP (Virtual Redundant Router Protocol) allowing multiple physi-
cal routers to share a single gateway and provide multiple backup WAN connections.
For complex network applications the MR-200 supports OSPF and RIP2. The MR-200
is supplied with a complete mounting kit for DIN rail, wall or shelf mounting. The wide
temperature range and 24VDC supply ensure that the MR-200 can be used in industrial
applications without the need for modification or consideration of the environmental
conditions.
The MR-250 has got all the functionality of the MR-200 plus EDGE, 3G and HSDPA
capapbility. The MR-250 will at all times use the communication method with the fastest
transmission speed. If HSDPA is not available the unit will automatically switch down to
3G, EDGE or GPRS respectively.
