Ltech LT-874-5A Manuals

1 LT-874-5A use with our LT-870 wireless emitter, supporting point to point, point to multi-point communication. One emitter can match multiple receivers if using the same frequency, self-testing function also available. LT-874-5A 4CH CV DMX decoder with OLED display, receiving standard DMX512 protocol data wirelessly. LT-874-5A Wireless DMX512 Decoder LT-874-5A 2.4G Wireless DMX512 Decoder warranty 5 years Use relay settings or connect to booster antenna to further the communication distance. Adopt 2.4GHz global open ISM frequency channel, 64 groups wireless network can be chosen independently to avoid interference. 1.

E.g.: Set the frequency to 2437M. The value summation from 1~6 is 001+004+032=37, so the transceiver frequency is 2400+37=2437M. Value Press "M" key, switch entries. Press "∧" or “∨" key, adjust parameters. Long press "M" key, return to the main display interface(Figure 1). Exit: Return to the previous menu. LT-874-5A Wireless DMX512 Decoder LT-874-5A is used with LT-870 wireless transceiver, so its frequency must be same as LT-870. Dip Switch(1-6): www.ltech-led.com
