LT-874-5A 4CH CV DMX decoder with OLED display, receiving standard DMX512 protocol data wirelessly. use with
our LT-870 wireless transmitter, supporting point to point, point to multi-point Network structure. A transmitter can
configure multiple receivers as long as they use the same frequency, self-testing function also available.
Please refer to the OLED display for the detailed information.

Dip Switch(
: 64 frequency option(2401-2464MHz), Frequency interval: 1MHz (As following table).
1st to 6th)
Example, As figure 1, 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.

5. Dip Switch Operation:
Frequency value = the total place value amount of 1-6 dip 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.
