Frequently Asked Questions - CastMaster ACER

How do I connect my Android smartphone to the CastMaster?

Enable USB debugging on your phone: go to Settings > System > About phone, tap 7 times on 'Build number' to enable developer options, then enable 'USB debugging' in Developer options. Connect the phone to the CastMaster transmitter with a USB cable, then authorize USB debugging when prompted. The phone must be in MTP or file transfer mode.

Can the CastMaster be used wirelessly?

Yes, the CastMaster enables wireless casting via screen mirroring. The transmitter connects to your device (smartphone, tablet, PC) and the receiver connects to the projector or display via HDMI. The connection between transmitter and receiver is wireless.

What should I do if the LED flashes red?

A flashing LED may indicate a connection error or an ongoing OTA update. Check the LED table in the manual: flashing for 1 minute or more means a connection failure; verify that the devices are properly paired and nearby. If it is an OTA update, wait until it finishes.

How do I pair the transmitter and receiver?

Download the pairing file onto a USB key, plug it into the transmitter (TX) unit, then toggle the switch to the 'Mobile' position to start pairing. The operation is complete when the LED stops flashing.

Can I connect an iPhone to the CastMaster?

The manual mainly mentions Android and Windows. For iOS, AirPlay is not explicitly supported; check software updates or contact Acer support.

How do I update the firmware on the CastMaster?

The OTA update is done via the transmitter. Download the update file to a USB key, plug it into the transmitter, and follow the instructions. The LED will indicate progress. Do not unplug the device during the update.

What are the risks if I block the ventilation openings?

The openings must not be obstructed to prevent overheating. The device may overheat and damage internal components. Place it in a well-ventilated area and do not cover the slots.

Can I use the CastMaster with a non-Acer projector?

Yes, the CastMaster connects via standard HDMI, so it is compatible with any projector or display that has an HDMI input.

What should I do if the image does not display?

Check that the projector is on and set to the correct HDMI source. Ensure the transmitter and receiver are paired and that the transmitter LED indicates an active connection. Restart both devices if necessary.

How do I clean the CastMaster?

First, unplug the device. Use a soft cloth slightly dampened with water (no chemicals). Gently wipe the surface. Do not let moisture enter the openings.
