LT-855-12A with standard RDM remote device management protocol, supports DMX512 signal
bi-directional communication, achieves remote management of reading and writing DMX address
(DMX master controller must recognize the RDM protocol).
RDM Mode: The dip switch 1-10 are OFF.
FUN = ON (the 10th dip switch = ON)
Self-testing Mode:
FUN = OFF (the 10th dip switch = OFF)
DMX Mode:
Setting DMX addresses with dip switch 1-9
FUN = OFF (the 10th dip switch ) Mode= OFF DMX
3.1 How to set DMX address via dip switch:
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
DMX address value = the total value of (1-9), to get the place value when in “ON” position,
otherwise will be 0.
Short circuit / Over current,
