configuration – it cannot be assembled to the router at some point in the future.
The router can be equipped with PoE PD (Power over Ethernet – Powered Device), which
allows the router to be powered via Ethernet. It can also be equipped with PoE PSE (Power
over Ethernet – Power Source Equipment), which lets the router to power other devices via
Ethernet. The SmartFlex router can also be configured with a wide variety of port options.
These can be SWITCH – three switched Ethernet ports; RS232-RS485/422 – combination of
serial interfaces; RS485-RS485 – two RS485 serial lines; RS232-RS485-ETH – combination
of serial interfaces and Ethernet port with higher insulation. The router can be provided in
either a plastic or metal casing, depending upon the customer’s requirements.
Configuration of the router may be done via a password-protected Web interface. Web in-
terface provides detailed statistics about the router’s activities, signal strength, detailed system
log etc. The router supports the creation of VPN tunnels using IPSec, OpenVPN and L2TP
to ensure safe communication. DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS,
backup primary connection and many other functions are supported.
The router provides diagnostic functions which include automatically monitoring the PPP
connection, automatic restart in case of connection losses, and a hardware watchdog that
monitors the router status. The user may insert Linux scripts which are started on various
actions. It is possible to create up to four different configurations for the same router. These
configurations can be switched whenever necessary via Web interface, SMS or binary input
status. The router can automatically upgrade its configuration and firmware from your central
server. This allows for mass reconfiguration of numerous routers at the same time.
The router also supports additional software like
R-SeeNet
for permanent traffic monitoring
of routers or
WebAccess/VPN
for remote access.
