AI-Powered supplier vetting

SummarySHANDONG RENKE CONTROL TECHNOLOGY CO., LTD. is identified as a Jinan-based trading company operating in manufacturing-related industries, including integrated circuits and environmental monitoring instruments. The supplier reports ISO9001:2015, RoHS, CE, and FCC certifications. It provides extensive customization and ODM services, has introduced new products within the past year, and reports OEM service for well-known brands. Production-related information includes sensor productivity of 400,000 pieces and five quality inspectors, although finished-product inspection has instructions but no written records. The supplier lacks inventory, overseas warehouses, overseas agents or branches, and a valid manufacturing-capacity contract with affiliated subcontractors. Financial records are referenced for 2022–2024, but no monetary figures or detailed financial indicators are provided. Customer evidence is limited to one associated buyer name and does not establish the scope or quality of completed projects.

CertificationsThe supplier reports an ISO9001:2015 certificate and product certifications including RoHS, CE, and FCC. These certifications explicitly support quality-management and product-compliance capability.

After-Sales capabilityThe supplier reports no inventory capability, no overseas warehouse, no overseas showroom, and no overseas agents or branches. It also reports serving zero countries overseas, so the provided evidence does not demonstrate strong after-sales coverage, particularly internationally.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers customization from samples, designs, and full specifications. However, it reports no available SDK, so innovation capability is supported in product development and design services but not across all technical-development resources.

Production capacityThe supplier reports sensor productivity of 400,000 pieces, five quality inspectors, and production equipment including an MST mounter and auto-soldering and soldering capabilities. Nevertheless, it has no valid manufacturing-capacity contract with affiliated subcontractors, and its inspection and supplier-assessment procedures lack written records, limiting assurance of production control.

Customization capabilityBoth reported design-service fields list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability, providing explicit evidence of broad customization support.

Product Q&A

Q:Can a computer plug multiple USB to 485?

You can insert more than one, which has been verified by experiment.

Q:Can the serial number of the COM port automatically recognized by the computer be modified? For example, can the COM8 automatically recognized by the computer be modified to COM3?

It can be modified. It can be modified if it does not conflict with the existing COM port that comes with the computer. Specific method: right-click on the communication port COM? to be modified-left click to select Properties-left click to select port settings-left click to select advanced-Select the COM port that does not conflict with the computer in the COM port number.

Q:The COM port can be recognized in the computer, but it can't communicate?

First, check whether the wiring is correct, it is usually a wiring problem; for USB to 485: If the communication distance is too long, check whether the 120R matching resistance at the beginning and end of the bus is correctly connected, etc.

Q:Sometimes it can be recognized, sometimes the computer can't recognize the conversion cable hardware?

For compatible assembled computers, be sure to plug the conversion cable into the USB port on the back of the motherboard. It may be better for branded computers, but it is also recommended to plug it into the USB port on the back of the motherboard. Notebooks generally do not have this problem.

Q:Where can a USB to rs485 converter be applied?

It is usually used with our rs485 sensor equipment and directly connected to the computer to obtain the value.
