Frequently Asked Questions - VLSC151H Vivolink

How do I switch between input sources on the VLSC151H?

You can switch inputs using the front panel buttons (1-HDMI/MHL, 2-HDMI, 3-HDMI, 4-DP, 5-VGA), the IR remote, RS232 commands, or via the web-based GUI. In auto-switching mode, the switcher automatically selects the latest active input.

What output resolutions are supported?

The scaler supports output resolutions: 1920x1200, 1920x1080, 1600x1200, 1600x900, 1360x768, 1280x800, 1280x720, and 1024x768.

Can I control the switcher via RS232?

Yes, the VLSC151H has a 3-pin Phoenix RS232 port. Use a baud rate of 9600 (default), 8 data bits, 1 stop bit, no parity. Send commands like '50701%' to switch to HDMI 1, '50619%' to set resolution to 1360x768, etc.

How to use the OSD menu?

Press and hold the AUTO/MENU button on the front panel for 2 seconds, or press MENU on the IR remote, or send RS232 command '50616%'. Navigate using direction keys (up/down/left/right) and confirm with ENTER/OK.

What are the microphone connection options?

The MIC input supports three modes via a 3-level dial switch: 48V phantom power for condenser microphones, MIC mode for dynamic microphones, and LINE mode for wireless microphones or line-level audio. Balanced or unbalanced connections are possible.

How does auto-switching work?

In auto-switching mode, the switcher automatically selects the most recent active input. On power-up, it restores the last configuration. If the current signal is removed, it scans inputs from 1-HDMI/MHL to 5-VGA and switches to the first detected signal. Note: auto-switching is disabled when a VGA port is set to C-video or YPbPr.

Can I update the firmware?

Yes, firmware can be updated via the USB Type-A port (labeled FIRMWARE) using a USB flash drive, or through the web-based GUI at http://192.168.0.178:100. The update file must be provided by the manufacturer.

What is the default IP address for web control?

The default IP address is 192.168.0.178. Log in with username 'user' and password 'user'. You can change network settings (static/dynamic) via the Configuration menu.

How do I perform a factory reset?

Use RS232 command '50617%' or navigate to Setup > Restore Factory Default in the OSD menu. This resets all settings to factory defaults.

What should I do if there is no image on the output?

Check the following: ensure all cables are securely connected, verify the input source is active, try a different HDMI cable, confirm the output resolution is supported by your display, and check if the front panel is locked (unlock with RS232 command '50605%'). If issues persist, contact customer service.

3.4 Connection of Microphone

The Scaler Switcher provides with one 3-level microphone input port, to accommodate different microphone input modes, including 48V phantom power mode, MIC mode & LINE mode.

48V phantom power Mode

48V phantom power input has a good frequency characteristic, high input impedance and high sensitivity.

When switching to "48V", the MIC input will provide a 48V phantom power. This is only used for condenser microphone.

Connect the microphone in this way: “+” connects to positive, “-” connects to negative and “-” to ground.

MIC Mode

MIC input has a low frequency characteristics, and wide frequency response.

When switch to "MIC", the microphone input is used for connecting with dynamic microphone. There are two different connection methods:

1) Unbalanced connection:

“+” and “≡” connect to ground, and “-” connects to signal. “-” and “≡” connect to ground, and “+” connects to signal.

LINE input has a low frequency characteristics, and wide frequency response.

When switch to "LINE", the microphone input is used for connecting with line audio or wireless microphone output. There are two different connection methods:

1) Unbalanced connection:

“+” and “ 1= ” connect to ground, and “-” connects to signal. “-” and “ 1= ” connect to ground, and “+” connects to signal.

2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ± ”

connects to ground.

3.5 Application

The Scaler Switcher has a good application in various occasions, such as computer realm, monitoring, conference room, big screen displaying, television education, command & control center and smart home etc.

4. System Operations

4.1 Front Panel Buttons

Front panel buttons can be used for switching operations and volume adjusting.

4.1.1 Manual-Switching

Press 1-HDMI/MHL, 2-HDMI, 3-HDMI, 4-DP, 5-VGA on front panel to select the corresponding input source.

4.1.2 Auto-Switching

Press AUTO to enter in auto-switching mode.

The auto-switching mode abides by the following principles:

New input

Once detecting a new input signal, the switcher would switch to this new signal automatically.

Rebooting device

The Scaler Switcher have the ability to save the last configuration before losing power. If the last switching mode is auto-switching, once rebooted, the switcher will automatically enter auto-switching mode, then detect all inputs and memorize their connection status for future rebooting using. If the last displayed signal is still available, the unit will output the signal. If not, the unit will detect all the input signals with priority from 1-HDMI/MHL to 5-VGA. When detected the first signal, it will transfer to output.

▶ Signal removing

Once removing the current display signal, the Scaler Switcher will detect all input signals with priority from 1-HDMI/MHL to 5-VGA. It will transfer the signal firstly detected to be available to output devices.

Note:

• When the DP signal is switched as input, the DP source device may not read the EDID data from display device, at this point re-plug the DP source device to solve this phenomenon.
  ● Auto-switching function works only when inputting new signal, removing a signal or power rebooting. With any VGA port set to C-video or YPbPr, the system will be not able to enter in Auto-switching mode.

4.1.3 Volume Adjusting

Press Volume Knob to choose MIC/Source audio needed to be adjusted, the corresponding LED will turn green and keep on.

• Adjusting the Volume Knob in clockwise direction to increase sound volume.
• Adjusting the Volume Knob in anti-clockwise direction to decrease sound volume.

4.2 IR Control

4.2.1 IR Remote

Connect IR receiver to IR EYE port, the Scaler Switcher cans be controlled by using IR remote. As CEC function, it is able to use the IR remote to turn on/off the HDMI source or Display.

① Enter/ exit standby mode
② Input channel selection buttons(1\~5): Select video source via pressing corresponding button (audio switched following the corresponding DP/VGA)
③ Auto button: Enter/Exit auto-switching mode.
④ Mute/ unmute audio
⑤ VOL: Volume adjusting button. After pressing this button, the volume adjusting menu will be showed on Display, and then press UP/DOWON button to increase/decrease volume.
⑥ OK: confirm button; Navigation buttons: UP/DWON/LEFT/ RIGHT button, for value setting or page-turn.
⑦ Exit button: Exit OSD menu or current operation.
⑧ Enter OSD menu or used to return to previous menu.

4.2.2 CEC Function

The Scaler Switcher supports CEC, it can be turned on/ off by sending RS232 commands or OSD menu operations. The default setting is ON.

Commands pertaining to CEC: "50686%" (enable CEC) and "50687%" (disable CEC)

HDMI INPUT ports 1\~3 support CEC, if the connected source devices also support CEC and their CEC are on, users can control the source device and display via the IR remote of the Scaler Switcher.

The working status related to CEC and STANDBY is showed as below:

Situation	Working Status
CEC: on, Standby: on	Press STANDBY button on IR remote, the Scaler Switcher enters in standby mode, so do all HDMI source devices and display.Press STANDBY button again on IR remote, the Scaler Switcher exits standby mode, the previous selected HDMI input source device and display start working too.
CEC: on, Standby: off	Press STANDBY button on IR remote, the Scaler Switcher enters in standby mode, HDMI 1~3 source devices and display keep on.
CEC: on	Use and remote to control HDMI source device.
CEC: off	Unable to control HDMI source device and display through IR remote

4.3 RS232 Control

The Scaler Switcher can be controlled by sending RS232 commands. The baud rate of RS232 port support 2400, 4800, 9600(default), 19200, 38400, 57600 or 115200.

4.3.1 Installation/uninstallation of RS232 Control Software
