Define Parameters
Once you have added and specified all of the parameters for the new fixture, you can now define
the address requirements, size, and ranges for each of them.
To define the size (8-bit or 16-bit) of any parameter:
Step 1: Use the [Page] keys to navigate to any parameter that you wish to alter the size of.
The system defaults to 8-bit for any new parameter.
Step 2: When selected, press {Size}. This will toggle the parameter from 8-bit to 16-bit. If 16-
bit is selected, the system automatically applies a value in the “LDMX” column. This
value can be altered (see below).
To define the DMX address of any parameter:
You can alter the default DMX address assigned to any parameter in the list. This is not the actual
address that will be used when patched, but rather it is the order of address for the parameter
relative to the other parameters in the fixture.
Step 1: Use the [Page] keys to navigate to the “DMX” column of the desired parameter.
Step 2: Enter the desired address using the keypad.
To define the LDMX address of any 16-bit channel:
LDMX or “low-DMX” is the DMX address for the second half of any 16-bit channel. If used in
Coarse/Fine determination. The DMX channel defines the “Coarse” adjustment and the LDMX
defines the “Fine” adjustment.
Step 1: Use the [Page] keys to navigate to the “LDMX” column of the desired parameter.
Step 2: Enter the desired address using the keypad.
To alter the Home settings for any parameter:
You can define the value for any parameter’s “home” value.
Step 1: Use the [Page] keys to navigate to the “Home” column of the desired parameter.
Step 2: Enter the desired home value (0-255 for 8-bit, and 0-65535 for 16-bit) using the
keypad.
To enable the Snap setting for parameters:
You can enable snap for parameters to exempt them from cue timing, so they snap to their new
value. For more information about snap, see Snap Parameters, page 93.
Step 1: Use the [Page] keys to navigate to the “Snap” column of the desired parameter.
Step 2: Press {Snap} or click in the ‘Snap” column for the selected parameter to enable.
CAUTION:
Be careful not to duplicate any address in the DMX order of parameters in the new
fixture. Ion does not prevent you from duplicating addresses.
