Usage Instructions

Connect Device

• Connect your MEMS-VCSEL module (or SZ system) to the PC via USB.
• Power on the device.

Launch Utility

• Open MEMS-VCSEL Utility from the Start Menu or desktop shortcut.
• The software should auto-detect the COM-port device.

Verify Connection

• Check that the module appears in the device list.
• If not detected, ensure drivers are installed correctly and try a different USB port.

Configure Operation

• Use Mode Configuration Switches to select the operating mode.
• Adjust Delay and Output Power values — updates apply instantly (no “Save” needed).
• View the Sweep Rate and system status directly in the GUI.

Error Monitoring

• Any device errors will appear in the Error Code Display.
• Refer to the device manual for error code meanings and corrective actions.

Save/Load Settings

• Optional: Save preferred configurations for repeat experiments.
• Settings can be reloaded at startup for faster setup.

Care & Maintenance

Software Care

• Always use the latest version of the MEMS-VCSEL Utility (currently v2.3.1) to ensure bug fixes and Windows compatibility.
• Keep your Windows OS updated to avoid driver conflicts.
• Regularly back up your saved configurations in case of reinstallations or OS resets.
• Close the software properly before disconnecting the device to prevent corrupted settings.

Device Handling

• Connect the MEMS-VCSEL module only via approved Thorlabs cables/adapters.
• Avoid plugging/unplugging while the software is actively communicating with the device.
• Ensure stable USB connection—use direct ports instead of hubs where possible.

Cleaning

• Clean the external housing of the MEMS-VCSEL unit with a lint-free dry cloth.
• Do not use solvents, alcohol, or abrasive materials near optics or electrical ports.
• Keep optical connectors and fiber ends dust-free; use proper fiber cleaning tools.

Environment

• Operate in a clean, dry laboratory environment with stable temperature and low dust.
• Avoid exposing the device or PC interface to vibrations, shocks, or humidity.
• Store the system in its protective case when not in use.

Maintenance Checks

• Periodically check error codes within the software for signs of degraded performance.
• Verify sweep rate stability and output power levels regularly for consistency.
• If unexpected behavior persists, reinstall the software and drivers before contacting support.

Service

• The MEMS-VCSEL Utility itself requires no user-serviceable parts.
• For persistent errors or hardware faults, contact Thorlabs Technical Support.
• Only trained technicians should attempt hardware repairs or firmware modifications.
