Network Activity Led; Rotary Encoder - Lab.gruppen PLM series Operation Manual

MENU mode is described in full in section 9.12.

9.7 Network Activity LED

Located above the rotary encoder is an ultra-bright white LED. This LED illuminates when there is
network activity between the Lake Controller software and the PLM.
The Network Activity LED can be dimmed via the
front panel by selecting Frame menu, and then Front
- Dimming.
This feature is useful for two reasons:
1) It provides visual confirmation that there is network communication between the Lake Controller software
and PLM.
2) It enables the engineer to visually confirm which PLM is selected via the Lake Controller software,
especially if parameters are being changed.

9.8 Rotary Encoder

The rotary encoder is used to alter various PLM parameters (e.g. input level) in conjunction with the various
display pages. The ring around the knob illuminates when any menu item is selected that allows adjustment
by the rotary control.
Turn the encoder clockwise to increment (raise) the selected parameter or counter-clockwise to decrement
(lower) it. Parameters with only two states (e.g. ON, OFF) are toggled by turning clockwise or counterclock-
wise.
With several PLM parameters, it is possible to enable simultaneous adjustment of a combination of input
and output channels. To select which channels are adjusted press the associated soft button. This toggles
the displayed parameter value between normal text and 'inverse video' text. When highlighted, the rotary
controller alters the parameter value. Note: Certain MENU screens, such as MENU > Module > Limiters >
ISVPL, permit parameters to be adjusted across all four output channels simultaneously by default.
An example:
1. First select the parameter that requires changing via the MENU screen. e.g. ISVPL.
2. Press MENU > Module > Limiters > ISVPL
The current ISVPL values for output channels 1 to 4 are displayed on the right hand of the screen and the
ring surrounding the rotary encoder is illuminated indicating that the rotary encoder is active.
