Ltech LT-874 Series Manual

2.4G Wireless DMX512 transceiver
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.
Adopt 2.4GHZ global open ISM frequency channel, 64 groups wireless network can be chosen independently to
avoid interference.
use relay settings or connect to Booster Antenna to further the communication distance.

simultaneously, LT 874 5A will restore the default parameters, and the screen display -
then it will return to the main display interface Figure 1
5. Dip Switch Operation:
Dip Switch( 1st to 6th)
DIP 1
Value 001
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,
Remark
put dip switch to OFF position, its place value is 0.
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.
