This holds a comma-separated string listing the human-readable enumeration values that valueRfInput's sibling object valueLaserMode can take, matching numeric codes starting at 1 (for Laser Mode that's preset(1), set(2), setEquate(3), manual(4), or manualEquate(5)). Management software reads this string dynamically to build a drop-down or label for the control that selects how the laser's output level is controlled, from a fixed factory preset through to fully manual control, instead of hardcoding the enumeration text for every possible parameter in the client itself.
