r.PAn
– Reverse pan. This setting allows you to invert the pan so that
opposing fixtures will pan in the same direction given the same command from
the controller.
To invert the pan:
1. Press the
[UP] or [DOWN] button until the display reads r.Pan .
2. Press the [ENTER] button.
3. Press the [UP] or [DOWN] button until the display reads On .
4. Press the [MODE] button to get out of the r.Pan mode.
r.t!t
– Reverse tilt. This setting allows you to invert the tilt so that
fixtures that are rigged inverted (e.g., hanging from a truss) will tilt in the same
direction as fixtures that are rigged upright (e.g., sitting on the floor) given the
same command from the controller.

1. Press the
[UP] or [DOWN] button until the display reads r.tilt .
2. Press the [ENTER] button.

16b.r.
– Resolution of movement. This setting allows you to choose
between 16-bit resolution and 8-bit resolution. 16-bit resolution requires two
channels for pan (course and fine adjust) and two channels for tilt (course and
fine adjust), but it gives you 65,536 steps of resolution which translates to
smoother movement and higher target accuracy. 8-bit resolution requires only
one channel for pan and one channel for tilt, but it only gives you 256 steps of
resolution over 540 degrees of movement in the pan and 270 degrees of
movement in the tilt. That translates to about one degree per step in the tilt
function, which, over a throw distance of 35 feet, is about 8” of movement per
step. If you are concerned about having enough DMX512 channels to run all of
your fixtures, you may consider changing this function to the 8-bit setting to free
two channels per fixture.
To change the setting of the movement resolution:
1. Press the
[UP] or [DOWN] button until the display reads 16b.r.
2. Press the [ENTER] button.
3. Press the [UP] or [DOWN] button until the display reads OFF .
4. Press the [ENTER] button.
5. Press the [MODE] button to get out of the 16b.r. mode.
