## YuDash ZENYX Overview <a href="#h.4p90d3pdegr5_l" id="h.4p90d3pdegr5_l"></a>

YuDash ZENYX is compact Industrial IoT Gateway, part of YuDash IoT Gateways and Data Loggers. It provides a flexible cloud connectivity to industrial and environmental instruments, PLC/HMIs and equipment. It supports a host of industrial protocols, including Modbus RS485, MODBUS TCP/IP, analog inputs. ZENYX acts as Modbus master and reads up to 96 parameters across 16 Modbus slaves. Four analog channels (0-20/4-20mA) are supported. ZENYX can connect to network (LAN or Cloud) through 4G/LTE, Ethernet and Wi Fi. ZENYX communicates with IoT platforms through MQTT, HTTP and FTP protocols. Effectively, any IoT platform can be connected using inbuilt JSON payload format library. It also has payload generator engine to support custom text and CSV payload.

ZENYX can be easily configured in web-browser through laptop or mobile phone. On-device OLED display shows running status and simplifies deployment and debugging. Advanced features like input data scaling, two-way communication through Modbus-write, low power variants are available to support various use-cases. JSON based configuration backup and restoration aids deployment at scale. Product variants with subset of features are available for a cost-effective IoT gateway depending on application.
