V. Common Product Issues and Solutions

Q1: What to do if the screen stutters, displays glitches, or disconnects during projection?

This problem is usually caused by two main reasons: signal interference or excessive distance.

Interference Troubleshooting: Check for strong signal obstructions such as metal or concrete walls between the transmitter and receiver, and remove or reposition them. Check for other devices operating on the same frequency band (e.g., 2.4GHz Wi-Fi) nearby, and stagger their frequencies or prioritize the 5GHz or 900MHz band provided by the device.

Distance Optimization: Ensure the device is within its effective transmission distance (depending on the specific model and environment), avoiding extreme distance transmission.

Using a repeater: In long-distance or obstacle-ridden environments, the repeater function of the EWD611 radio can be used to build a repeater network, enabling relay transmission of signals and ensuring stable connections over long distances.

Q2: How to achieve "reverse control," i.e., controlling the signal source device with a keyboard and mouse on the monitor?

A model with a USB interface (such as the EWD612-HDMI/USB) is required. Simply connect the keyboard and mouse on the monitor to the receiver via the USB interface or a USB extender. The receiver will send the input signal back to the transmitter via the USB protocol, and the transmitter will then act as a USB hub, enabling remote control of the original computer or host, without requiring additional software configuration.

Q3: How is the stability of the EWD612 guaranteed in environments with strong electromagnetic interference, such as factories?

This is where the core advantages of the EWD612's professional-grade design lie:

Hardware level: Employs a metal shielded casing and isolation design.

It also supports data packet verification and retransmission mechanisms, automatically correcting errors during network fluctuations.

Q4: Can the equipment operate stably in both northern and southern regions, and in high and low temperature factory environments?

Yes, it can operate stably. This series offers two options: "Commercial Grade" (0℃~70℃) and "Industrial Grade" (-40℃~+85℃). When purchasing, you need to clearly specify the application environment temperature requirements to the supplier and select the corresponding industrial grade model. This is suitable not only for low-temperature scenarios such as chemical plants and cold storage facilities, but also for high-temperature workshops such as steel mills and foundries.
