data transmission
LT-870 Wireless DMX512 transceiver transfers the standard DMX512 protocol data by wireless transmission. One send,
one receive or multiple receive. (Supporting point to point, point to multi-point), a sending end can configure multiple
receiving ends as long as the receiving end and sending end are set as same frequency point.
The product is used for DMX console and lamp. The wireless data transmission between lamps replaces cable transmission
which relies on twisted-pair, etc., for a long time. No delay and data is real-time and reliable during data transmission
process,
The product adopts 2.4GHZ RF global open ISM frequency channel, which is a low-cost, powerful wireless DMX512
transceiver and widely applied to DMX512 controllers from various manufacturers.
64 channels choices, users can use 64 groups wireless network independently without interference in one place.
Use relay Settings if need further increase the communication distance.

The 1-6 Dip switch:64 frequency to choose (2401~2464MHz), the interval of frequency is 1MHZ. (see the below form)
Example, As figure 5, the repeater frequency is 2437M, set the 1st, 3rd , 6th dip switch to “1”, the rest to “0”, the Value
summation from 1-6 is 1+4+32=37, so the repeater frequency is 37+2400=2437M.

Frequency value = the total place value amount of 1-6 dip switch+2400,
put the dip switch to ON position, user can get its place value,
put dip switch to OFF position, its place value is 0.
