Auto 6M Use Full Console Range

There are two different ways of how the multipliers are calculated, depending on whether or not the advanced property in the System Settings is enabled or not.

Option 1: Property "Auto 6M Use Full Channel Range" is enabled:

Let auto_value be the value calculated based on autofunctions/smart zoom and console_value the one received from the console on the fixture's input universe. Furthermore, let dmx_full_range_min and dmx_full_range_max be the theoretical dmx value limits, regardless of the limits set in the fixture's fixture type. Then the final channel value final_value is calculated by using the following formula:

multiplicator = 2 * ((console_value - dmx_full_range_min) / (dmx_full_range_max - dmx_full_range_min))
final_value = auto_value * multiplicator

For example, consider a fixture with an 8-bit IRIS channel (theoretical DMX values of 0-255), but a limited dmx range defined in its fixture type (e.g. DMX values of 0-131). With Auto 6M mode active…

…sending an IRIS value of 0 (0 % of theoretical dmx range) from the lighting console leads to the final IRIS value being 0, regardless of autofunctions or other factors (due to the multiplicator being 0 as well).
…sending an IRIS value of 127 (50 % of theoretical dmx range) from the lighting console leads to the final IRIS value being exactly the same as auto_value (due to the multiplicator being 1).
…sending an IRIS value of 255 (100 % of theoretical dmx range) from the lighting console leads to the final IRIS value being twice as big as auto_value (due to the multiplicator being 2).

Option 2: Property "Auto 6M Use Full Channel Range" is disabled:

Let auto_value be the value calculated based on autofunctions/smart zoom and console_value the one received from the console on the fixture's input universe. Furthermore, let dmx_min and dmx_max be the dmx limits as specified in the fixture's fixture type. Then the final channel value final_value is calculated by using the following formula:

multiplicator = 2 * ((console_value - dmx_min) / (dmx_max - dmx_min))
final_value = auto_value * multiplicator

…sending an IRIS value of 0 (0 % of limited dmx range) from the lighting console leads to the final DIMMER value being 0, regardless of autofunctions or other factors (due to the multiplicator being 0 as well).
…sending an IRIS value of 65 (50 % of limited dmx range) from the lighting console leads to the final IRIS value being exactly the same as auto_value (due to the multiplicator being 1).
…sending an IRIS value of 131 (100 % of limited dmx range) from the lighting console leads to the final IRIS value being twice as big as auto_value (due to the multiplicator being 2).
…sending an IRIS value of 255 (195 % of limited dmx range) from the lighting console leads to the final IRIS value being almost four times as big as auto_value (due to the multiplicator being 3.9).
