System description
The Linux router CAR-A-WAN. 112 connects local devices connected via
LAN or WLAN to the Internet using up to three data modems. System rules,
such as user-defined rules, control the dial-in behavior.
The power management controls the follow-up time and the almost
complete disconnection from the 24V DC power supply, or correct cold
starts during a manual restart or triggered watchdog of the embedded PC.
Two SIM cards are switchable, each connected with a 3G / LTE modem,
LEDs (inside the housing) signal the operating states, a speaker can emit
warning tones, an optional, tactile switch can trigger the reset of the
router.
The modems transfer their operating heat to the aluminium housing. Plug
connections for the connection of power supply and antennas facilitate
installation and allow installation and removal without tools.
