Frequently Asked Questions - SC61E Alfatron

How do I connect Alfatron SC61E to my network?

Connect the power adapter to the switch and plug it into an outlet. Then, use Ethernet cables to connect your devices (e.g., computer, router) to any of the switch ports. The switch will automatically configure itself.

Why is the power LED not lighting up?

Ensure the power adapter is securely connected to the switch and the outlet. If the LED remains off, try a different outlet or contact support. The adapter output should be 5V DC.

How can I reset the SC61E switch to factory defaults?

Locate the reset button on the front panel (may be pinhole). Use a paperclip to press and hold it for about 10 seconds until the LEDs blink. Release and wait for the switch to reboot.

What is the maximum cable length supported?

The switch supports Ethernet cables up to 100 meters (328 feet) per port for 10/100/1000 Mbps speeds.

Does the SC61E support VLANs or managed features?

This is an unmanaged switch, so it does not support VLANs or other management features. It is plug-and-play.

Can I mount the switch on a wall?

Yes, the switch has mounting holes on the bottom. Use appropriate screws and anchors for your wall type. Ensure the switch is placed in a well-ventilated area.

What should I do if a port is not working?

First, try a different Ethernet cable and ensure the connected device is powered on. Check the port LED: green indicates a link, blinking indicates activity. If still not working, try a different port on the switch.

Is the SC61E compatible with PoE devices?

No, this switch does not support Power over Ethernet (PoE). It only passes data. Devices requiring PoE will need a separate power source or a PoE injector.

How to clean and maintain the switch?

Unplug the switch before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents. Ensure vents are free from dust.

Where can I download the user manual for SC61E?

The manual is available for download on the Alfatron support page at notice-facile.com. You can also request a translated version via email.

5. Button Control

5.1 Manual Switching

When the switcher is in the manual switching mode, the Auto Mode LED goes out. If need to change the input source, please directly press the 1, 2, 3, 4, 5 or 6 button, and the corresponding LED illuminates green immediately.

5.2 Automatic Switching

Press and hold the AUTO button at least three seconds to enable automatic switching, and the Auto mode LED will light.

When in the Auto mode, the switcher will switch according to the following rules:

• The switcher will switch to the first available active input starting at input 1 to 6.
• New input: The switcher will automatically select the new input once detecting a new input.
• Reboot: If power is restored to the switcher, it will automatically reconnect the input before powered off.
• Source removed: When an active source is removed, the switcher will switch to the first available active input starting at 1-HDMI/MHL input.
• Press the Video Source button (1, 2, 3, 4, 5 or 6) can directly change the input source. If the corresponding source device is active, it will be switched as input source; otherwise, the switcher will switch to the first available active input starting at 1-HDMI/MHL input.
• Press and hold the AUTO button at least three seconds again can exit AUTO mode, but the input source will remain the current setting.

5.3 Display Control

The switcher supports CEC, and the DISPLAY CONTROL buttons on the front panel are designed for Display On/Off and volume adjustment.

5.5 EDID Setting

The Extended Display Identification Data (EDID) is used for the source device to match its video resolution with the connected display. By default, the source device obtains its EDID from the first connected display. Meanwhile, since the displays with different capabilities are connected to the switcher, the 4-pin DIP switch on the rear panel can be used to set the EDID to a built-in fixed value. Use the following table to determine the setting for the 4-pin DIP switch for specific video resolution and audio capabilities.

The switch represents "0" when in the lower (OFF) position, and it represents "1" while putting the switch in the upper (ON) position.
