Controller operation

To connect for controller operation

1 Connect a data cable to the controller’s data output. If controller has a 5-pin output,

use a 5-pin male to 3-pin female adaptor cable (P/N 11820005). Lead the cable from

the controller to the first fixture and plug it into the data input.

2 Connect the output of the fixture closest to the controller

to the input of the next fixture. If connecting to a fixture

with reversed-polarity (pin 3 cold), insert a phase-

reversing cable between the two fixtures.

3 Continue connecting fixtures output to input. Up to 32

devices may be connected on a serial link.

4 Terminate the link by inserting a male termination plug

(P/N 91613017) into the data output of the last fixture. A

termination plug is simply an XLR connector with a 120

ohm, 0.25 W resistor soldered across pins 2 and 3.

MODE SELECTION

The MiniMAC Maestro has 4 control modes for operation with DMX512

controllers. The modes mix tracking and vector control with 8 and 16-bit gobo, pan,

and tilt position control in different combinations. Mode 1 provides basic control

and requires the fewest channels. Mode 4 provides the full set of control options.

TRACKING VERSUS VECTOR CONTROL

With tracking control (all modes) the speed at which an effect changes from one

position to another (fades) is determined by programming a fade time between 2

scenes using a cross-fader.

With vector control (modes 3 and 4), speed is programmed on separate speed

channels. This provides a way to program fades on controllers without cross-faders.

With some controllers, vector control provides smoother movement than tracking

control, particularly at slow speeds.
