Monitors routing system heartbeat every 1 second. If no heartbeat is detected within 120 seconds (system crash), it shuts down and restarts the entire system within 15 seconds. The routing system also independently controls each 4G module's power supply — automatically power-cycling any module that fails to dial.Power Supply Parameter Min Rated Max Unit Working Voltage 6 12 14 V Absolute Working Voltage 5.5 — 16 V Working Current (VIN=12V) 0.4 0.6 1 A ⚠️ Use the ZBT standard 12V/1A power adapter.
