Dip Switch Operation:
3.
When Dip switch 1-9 are OFF, the defaulted .initial DMX address is 1
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37. E.g.3: Set Initial Address To 178.
001+004+032=37 002+016+032+128=178

3.1 How to set DMX address via dip switch:
FUN=OFF (the 10th ) Modedip switch=OFF DMX
DMX address value=the total value of (1-9), to get the place value when in “on” position,
otherwise will be 0.
3.2 Self-testing Mode:

LT-851-5A DMX-PWM Decoder
*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.
