Routers handle harsh environments

Westermo Data Communications product story

ED-200 and ED-210 routers combine the functions of a switch and a packet filter for short or long distance network interconnections.
Westermo Data Communications has released a range of industrial Ethernet routers with integrated four-port switches.
As PPP routers they employ dial-in or dial-out, and are used to link several local Ethernet networks or to gain access to a remote Ethernet network.
They provide high levels of security and handle harsh environments, making them suitable for applications as traffic signalling, water treatment, aerospace, petrochemical and mining.
ED-200 and ED-210 routers combine the functions of a switch and a packet filter for short or long distance network interconnections.
The ED-200 has an RS-232 or RS-422 standard serial port.
It offers a wide range of communication possibilities when using standard Westermo PSTN, ISDN, GSM or radio modems.
The ED-210 has an integrated V.34 PTSN modem equipped with transient protection on the line side and a "watchdog" that monitors and automatically resets the modem in the event of a fault.
To guarantee a high level of security, both the ED-200 and ED-210 provide multiple-user identification or call-back security and passwords along with a simple IP level firewall.
They have galvanic isolation and enhanced surge/transient protection on all ports, and an extended working temperature range of - 25C up to +70C.
This enables the devices to be used in projects where a high degree of reliability is required.
Connection of the ED-200 with an external Westermo modem is totally transparent, so no additional software is necessary.
Communications statistics are easily available everywhere in the network, using a web tool.
