called for. While operating as a strobe, the intensity and color controls
remain in effect.

Placing both switches in the “up” position selects mode 4. This mode
provides the ultimate control over color saturation and hue, but uses the
largest number of DMX channels: five per pod, twenty for the entire LP-
LED4. In each group of five, the first four channels control the intensity of
the individual red, green, blue and white LEDs in the pod, while the fifth is
an overall intensity control for the pod, allowing it to be dimmed without
changing the proportions of the four LED colors. Note that this fifth overall
intensity channel should be set at or above 75% (192 if your controller reads
out the values in decimal or 0C0 if it reads in hexadecimal) while the other
four are used to mix colors. Once the desired color is obtained, its intensity
can be varied without changing the color by adjusting the fifth channel.
Again, to mix the colors accurately, as well as to avoid damaging your eyes,
watch the scene, not the LED pod.

Address Switches

For those true geeks who can do binary math in their heads, the left-most
switch is the least-significant bit, down is 0 and up is 1. For the rest of us,
appendix A is a chart which indicates the switch settings required for all
useable DMX addresses. The address listed is the first channel assigned to
pod 1. Additional channels above that are assigned according to the mode
selected.

“ALIVE” LED

The LP-DMX3/LP-DMX5 uses a microprocessor to receive the DMX-512
and turn it into the LP-LED4 control signals. The microprocessor spends
most of its time waiting for something to do. While it’s waiting, it does a
self-test. At the end of the test, it toggles the ALIVE LED: if the LED is on,
the microprocessor turns it off and if the LED is off, the microprocessor
turns it on. If the ALIVE LED stops blinking, the microprocessor has failed
its test.
