7 Lighting Setup
Lighting is labelled with either a voltage or current rating. This rating is the supply to the lighting that
should be used to get 100% continuous brightness from the light.
The NL-200 is compatible with both current and voltage rated lighting.
Before connecting a light the rating of the light must be entered. If a light is replaced with a different
type of light, then the rating must be set first. If a light is replaced with the same type of light then the
previous rating will still apply.
Consult the specification or labelling for the light. For commercially available lighting modules, if a
voltage and current rating is given, it is usually correct to use the voltage rating. If a voltage and watt-
age rating is given, use the voltage rating. Otherwise use the current rating. In all cases the light is still
driven with a constant current. For “homemade” lights using single LEDs or arrays of LEDs use the
current rating from the LED datasheet.
The current rating can be set from 0.01A to 4A in steps of 0.01A. The voltage rating can be set from
12V to 36V in steps of 1V.
When a voltage rated light is connected, the NL-200 automatically senses the current rating of the
light.
Voltage and current rated lights are both driven with a constant current. This gives better brightness
stability and allows the NL-200 to prevent the light being driven with too much power.
7.1 Setting the Rating for a Light
To set the rating of a light on the Ethernet versions of the NL200, use the VL command or the internal
webpages.
To set the rating of a light from the front panel, press and hold the SEL button for 1 second. The dis-
play will show “CH1”. Press DOWN to show “rAt” then press SEL. Use UP and DOWN to select the
channel to be set up. Then press SEL and select “Cur” for current rated lights and “Uol” for voltage
rated lights. Then press SEL and set the current. Press SEL to save the rating.
