C335 Series Edge Computing Gateways | User Manual 6 www.vantrontech.com
1.1 Product Overview
Vantron C335 series edge computing gateways were launched 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.
