4.4.8. and 4.4.9 CURVE USER (User definable control curves)
Here the setup menu for the control curve 1 and 2 can be activated. Individual brightness curves can
be programmed, just as necessary for a lamp. Later on these curves can be assigned to the dimmer
channels.
In the curve menu the encoder changes the position of the cursor in the x-axis (input); when the right
button is pressed, the y-axis (output) can be modified.
Example 1 (linear): Here the connection between
input (lighting control desk) and output (lamp) is
linear and 1:1. For normal use this simple curve
is adequate.
Example 2 (logarithmic): The output (lamp)
reacts even at low input values.
Example 3 (exponential): The output (lamp) reacts
very little to small inputs, but all the more when
the input is higher.
Example 4: Lamp does not react till input is at 50
% ,but in this case reacts linear.
Example 5: Lamp is controlled inversely. If the
input is 0 % ,the Lamp is activated to 100 %, if
input is 100 %, the lamp is off (0%).
4.4.10. PHASE CORR. (activate phase angle correction)
Usually this control parameter is set to "ON". It makes a brightness-linear light control possible. The
normal non-linearity, produced by the SRC´s phase angle control, is thereby compensated. This
function works in addition to the "User Curves".
This function should only be deactivated ("NO"), when this correction is made internally by the control
desk (e.g. MA Lightcommander I) and cannot be switched off.
4.4.11. MASTER/SLAVE (coupling of dimmers)
For coupling several dimmers, the master and slave part can be defined.
(see chap. "Connections"). There is no other effect on the dimmer.
Attention! For this function a 5 wire DIN cable must be used; MIDI cables often have only 3 wires!
4.4.12. UNIT NO. (cannot be used yet)
This parameter makes it possible to send out DMX data of the dimmer and read them externally via the
DMX interface. This function will only be usable when the new DMX norm is finished. Every dimmer
will then need to have its own address (unit number).
