1.1 Product Overview
Vantron C335 series edge computing gateways were launched by Chengdu Vantron
Technology Co., Ltd. to meet the needs of IIoT applications in various industrial scenarios.
This series supports a variety of industrial protocols to allow access by field industrial devices
such as PLCs, HMIs, sensors, etc. The edge computing functionality helps to achieve data
optimization at IoT edge nodes, which reduces the data volume accumulated in the field and
the central console. With standard MQTT protocol, the series provides a broad access to
industrial data platforms to facilitate the digital transformation of factories.
This series adopts industrial design with guaranteed quality and reliability to offer an ideal
solution for your IoT application. Meanwhile it provides access to Vantron BlueSphere cloud
platform for unified management to ease the efforts of users by real-time monitoring and
tracking, OTA updates, remote maintenance, task assignment and follow-up.

Description of the BTN button
-When a system upgrade drive is inserted in the SD slot or USB port, a short press of
the button for about 2 seconds will cause the status indicator to blink, suggesting
system upgrade is in progress. Once the upgrade finishes, the system will reboot
(from eMMC flash).
-When the button is pressed and held for 3-10 seconds, user configurations and
custom settings will be removed and the Gateway will be factory reset. Once finishes,
the system will reboot.
-When the button is pressed for over 10 seconds, user partitions will be formatted
and data in such partitions will be cleared.
