SX4® FOUR & SIX GOBO CHANGER Instructions





Channel and Mode setting switches are on the control box.  The "MODE" switch is the first one on the left, near the red LED.  Next are the DMX address switches.  Starting on the right "X1" then "X10" and then "X100" from right to left.

Address then x10 and X100

It is powered by 24 volt DC and controlled by DMX512, either from most color scroller power supplies or a standalone power supply. Once powered, the unit will show a red power LED to indicate the power is on. The unit is also fitted with a green LED which indicates the status of operation. After it is powered the unit needs to initialize to find the home position of the gobos. This takes about 2 seconds during which time the green LED will flash. Once the home sensing is complete the flashing will stop. If the LED is not lit then DMX is not present. If the LED continues flashing it means there has been a fault detecting the sensor and the unit operates but without correct index positioning.

GAM GOBO TABLE 001

MODE 0 OPERATION • MODE SWITCH = 0
Standalone single gobo select - for focusing

Set DMX address on SX4® - This number is the desk control (fader) channel. Gobo will change at the levels shown in the charts below. Moves at maximum speed and via the shortest route.

GAM GOBO Table 2

MODE 1 OPERATION • MODE SWITCH = 1
DMX gobo selector - one channel operation

Set DMX address on SX4® - This number is the desk control (fader) channel.Gobo will change at the levels shown in the charts below. Moves at maximum speed and via the shortest route.

 

MODE 2 OPERATION • MODE SWITCH = 2
DMX gobo select with direction and speed control- Two channel operation

Set DMX address on SX4® - This number is the desk control (fader)channel.Channel 1: Gobo will change at the levels shown in the charts as per Mode 1.Channel 2: Sets speed and direction of change as per chart below.

 

MODE 3 OPERATION • MODE SWITCH = 3
Standalone operation displays all gobos in sequence

Use the X100 switch on the SX4 to set direction and speed as per chart.

GAM GOBO Table 3

 

Use the X10, X1 switch on the SX4® to set display time of each gobo. Setting these switches from 1 to 99 varies the time in 0.1 second steps from 0.1 seconds to 9.9 seconds.


MODE 4 OPERATION • MODE SWITCH = 4
Standalone operation for less than maximum patterns - displays each gobo in sequence

X1 switch on SX4® will set the display time of each gobo from 1 to 10 seconds
Set on zero for 1 second
Set on 9 for 0 seconds
Moves between gobos at maximum speed.


X100 switch on SX4® selects the first position you use in the turret wheel
X10 switch on SX4® selects the last position you used in the turret wheel
If you have three patterns, you put them in positions 1,2,3, then put the x100 switch
to 1 and the x10 switch to 3 and the unit will auto-select those three positions only.
If x100 = 1 and x10 = 3 the selection order is 1,2,3,2,1,etc
If x100 = 2 and x10 = 5 the selection order is 2,3,4,5,4,3,2, etc
If x100 = 5 and x10 = 2 the selection order will be 5,6,1,2,1,6,5,6,1,2 etc.

MODE 5 OPERATION • MODE SWITCH = 5
Standalone operation for continuous rotation

X100 sets direction - select 1 for anticlockwise or 2 for clockwise rotation
X10, X1 sets speed of rotation - 00 is slowest and gradually increases in speed as the
number is increased up to a maximum speed reached at number 63.

MODE 6 OPERATION • MODE SWITCH = 6
Rotation only DMX controlled

Applies to single pattern disc effects
Select DMX control channel on SX4 switches x100, x10, x1
Selected channel fader operates speed and direction of rotation as per chart below.

GAM GOBO Table 4

MODE 7 OPERATION • MODE SWITCH = 7
DMX single channel linear indexing and rotation control

Applies to single pattern disc effects
Select DMX control channel on SX4® switches x100,x10,x1
Control channel fader operates index/rotate functions as per chart below.

GAM GOBO Table 5

MODE 8 OPERATION • MODE SWITCH = 8
DMX TWO channel linear indexing with variable speed rotation

Applies to single pattern disc effects and gobo discs
Select DMX control channel on SX4® switches - x100,x10,x1
Control channel fader has two functions
1. Operates as an indexing fader from zero to 99%
2. If set at 100% then it holds the disc into continuous rotation mode

GAM GOBO Table 6

MODE 9 OPERATION • MODE SWITCH = 9
DMX TWO channel highly accurate 16 bit linear indexing for all disc types.

Select DMX control channel on SX4® switches - x100,x10,x1:
Use channel 1 for whole degree positions and channel 2 for fine alignment positions between the single degree settings of channel 1
