FAQ
What does SunGene need to quote RS485 Modbus Remote Monitoring?
For a quotation, send these details: Device register map; Baud rate and parity settings; Number of RS485 devices; Preferred northbound protocol. We use them to select sensors, gateways, power and the data connection.
Can this connect to our existing platform?
Most projects use one of these paths: Modbus RTU polling on RS485; Documented Modbus TCP handoff to local SCADA; Documented MQTT handoff to a customer-owned platform. The final payload and protocol are confirmed before sample shipment.
Is SunGene a SaaS platform provider?
SunGene can provide agreed software, platform connections and data integration alongside equipment supply and farm BOM planning. We define functions, account ownership, recurring fees, testing and maintenance in the quotation. Local teams carry out onsite construction; SunGene can help coordinate them.
What is checked before samples are shipped?
We agree the selected models, accessories, power and interfaces. For connected equipment, we also check the destination network, protocol and data format. Required certificates must apply to the proposed model and target country.
