and other self-service terminals.
The standard configuration includes two Ethernet 10/100 ports, one USB 2.0 Host port, two binary inputs
and one output (I/O connector). The device also has two readers for 3 V and 1.8 V SIM cards, which are
located on the rear panel of the router. The router also includes a microSD card port that supports up to
64 GB card storage (32 GB in the case of SDHC cards). The router can be equipped with a WiFi module,
but this must be part of the initial 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; 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 interface 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, au-
tomatic 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 differ-
ent 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.
