The control board on the top side of the SC-780 allows you to assign the DMX fixture address, which is defined as
the first channel from which the SC-780 will respond to the controller.
If you set, for example, the address to channel 5, the SC-780 will use the channel 5 to 20 for control.
Please, be sure that you don't have any overlapping channels in order to control each SC-780 correctly and
independently from any other fixture on the DMX data link.
If two, three or more SC-780 are addressed similarly, they will work similarly.
For address setting follow this procedure :
1. Switch On the SC-780 and wait until the fixture reset has finished ("rSt" is flashing at the display).
2. Press the [Mode] key in order to access the main menu. Browse through the menu by pressing the [Up]
and [Down] keys until the display shows "A001". Confirm by pressing [Enter] key and the letter "A" will flash.
3. Use the [Up] and [Down] keys to select the desired address.
4. Confirm by pressing [Enter] or [Mode] to cancel.
Controlling:
After having addressed all SC-780 , you may now start operating these via your lighting controller.
Note:
After switching On, the SC-780 will automatically detect whether DMX 512 data's are received. If there are not
received these data's at the DMX input, the display will start to flash "A001" with actually set address.
This situation can be occurred if:
there is not connected the 3 PIN XLR plug (cable with DMX signal from controller) in the input of the SC-780
the controller is switch Off or is failed the cable or connector is failed or the signal wires are swap in the input
connector.
Note:
It's necessary to insert the XLR termination plug (with 120 Ohm) in the last lighting in the link in order to ensure
proper transmission on the DMX data link.
6.1 Lamp
The SC-780 is run with a HMI 575 lamp.
A relay inside of the SC-780 allows you to switch On and Off the lamp via itself control board on the top side or via
your controller without affecting the rest of the lighting.
6.2 Switching On and Off the lamp by control board
1. Switch On the SC-780 and wait until the fixture reset has finished.
2. Press the [Mode] key in order to access the main menu. Browse through the menu by pressing the [Up] and
[Down] keys until the display shows "LAMP". Confirm by pressing [Enter] key.
3. Use the [Up] and [Down] keys to select "On" for switch On the lamp and "Off" for switch Off the lamp and
press [Enter] to confirm or [Mode] to cancel.
Note:
If you switch On the lamp by control board, then switch Off the SC-780 and again switch On the whole unit, the
lamp will automatically Switch On.
If you switch Off the lamp by control board, then switch Off the SC-780 and again switch On the whole unit, the
lamp will not shine. (you have to use for Switch On the control board again or external controller).
