1. Technical Specs:
LT-870S is used for data transmission between DMX console and lights, or between lights and lights, which
replace the wired transmission. The data will not be delayed, will be true and reliable during transmission
process.
(weather/environment affects the actual values)
LT-870S with automatic frequency hopping function, LT-870S will automatically choose clear channel to
send DMX512 data when works as an emitter. and can search and match the correct channel to receive
DMX 512 data when works as a receiver.
Use relay settings or connect to booster antenna to further the communication distance.
