Configuration Diagram
Dip Switch Operation
- RDM Mode: The dip switch 1-10 are OFF
- DMX Mode: FUN=OFF (the 10th dip switch = OFF) Setting DMX addresses with dip switch 1-9
- DMX Mode: FUN=OFF (the 10th dip switch = OFF) Setting DMX addresses with dip switch 1-9
How to set DMX address via dip switch
FUN=OFF (the 10th dip switch=OFF) DMX Mode DMX address value = the total value
of (1-9), to get the place value when in “on” position, otherwise will be
0.
- E.g.1: Set Initial Address To 32.
- E.g.2: Set Initial Address To 37.
- E.g.3: Set Initial Address To 178.
Self-testing Mode:
FUN=ON (the 10th dip switch = ON) Self-testing Mode
For changing effects (Dip Switch 8/9=on): DIP switch 1-7 is used to realize 7 speed levels. (7=on, the fastest level When several dip switches are on, subjected to the highest switch value. As the figure above shows, the effect will be 7 colors smooth at 7 speed level.
DMX Dimming Instruction:
Each LT-830 8A DMX decoder occupied 3 DMX addresses when connecting the DMX console. e.g., the defaulted initial address is 1, please find their corresponding relationships in the form.
Wiring Diagram
Decoder can be connected to a variety of standard DMX512 devices:
LT-830-8A is equipped with 3 types DMX terminals for users’ selection. The upper diagram takes XLR-3 terminal as a example, same connecting method for the rest two: green terminal (with amplifier function) & RJ45 terminal
- An amplifier is needed when more than 32 decoders are connected, signal amplification should not be more than 5 times continuously.
- If the recoil effect occurs because of longer signal line or bad line quality, please try to connect 0.25W 90-120Ω terminal resistor at the end of each line.
The connection diagram of three DMX terminals:
The connection diagram of AMP signal amplifier terminal:
- Amplified the signal by AMP interface which connecting too many decoder and in overlong signal line, signal amplification should be no more than 5 times continuously.
Attention:
- The product shall be installed and serviced by a qualified person.
- This product is non-waterproof. Please avoid the sun and rain. When installed outdoors please ensure it is mounted in a waterproof enclosure.
- Good heat dissipation will prolong the working life of the controller. Please ensure good ventilation.
