The unit is used for environmental monitoring (e.g. temperature, humidity, voltage, leakage, smoke, airflow). It is also used as an I/O controller (e.g. door control, fans, generator, control panels, UPS, circuit breakers, alarms). Can use up to 700 different elements - notifications, triggers, timers, logic schemes, sensors, and dry contacts. Has a built-in Web interface with virtual sensors, logic schemes, different types of notifications, and control panels. Has a slot for an LTE modem for an ethernet connection reservation.
VT335i is a new model and it replaces VT335S. New features include:
2. "CAN" - digital connector RJ12 6P4C for the connection of CAN sensors/extensions/devices on a CAN bus. Modules can be chained together. Read the instructions at "CAN devises connection and", and "Setting up CAN".
"Orange LED" - orange LED for Ethernet port. It shows network traffic.
"Green LED" - green LED for Ethernet port. It shows network traffic. Flashes green when the system starts up. Shows the connection state (constant green light - the connection is established, blinking green - the connection attempt).
"LEDs: E1, E2" - status indicators for two 12V 0.25A outputs on the front panel.
The LED is ON (orange) - the output is ON (the initial state can be configured).
The LED is OFF (orange) - the output is OFF ((the initial state can be configured).
10. "Chassis grounding" - Chassis grounding, M4 thread. Enhances the immunity of the equipment against conducted and radiated RF disturbances. Please contact a professional electrician before connecting it.
11. "GNSS" - A hole for mounting the GNSS antenna. Antennas are purchased separately from VT335i and separately from VT740. Read more at GPS location, and GPS Service API.
12a. "Restart" - the button restarts the appliance. Hold the button for 2 seconds and then let go, and the system will restart.
12b. "Reset settings" - reset settings to default factory settings. Keep pressing the button for more than 5 seconds. The “ERR” LED will start blinking. This indicates that the factory restoration has started. Wait for 20-60 seconds for the system to restart. The “ACT” LED will start blinking once the system has been restarted. The device can be accessed now.
