JFX™ Series DMX 4-Channel Decoder
Step 2b. (DMX - Advanced Operation)
Advanced operation should only be performed by professional DMX installers. The DMX channels can be adjusted, which
allows the user to conserve DMX addresses that may be wasted when programming a large DMX installation. The factory
default is 4CH: 4 channels (address 001 – 004). See charts for 1CH, 2CH, 3CH, & 4CH settings (Figure 3).
Step 3. (DMX – Adjust Channel Settings)
a. Press and hold buttons 2 and 3 simultaneously for 2 seconds until 'cH' flashes on the display
(Figure 2 & Figure 4).
b. Press button 1 to choose 1, 2, 3, or 4 channel outputs (Figure 5)
c.
Press and hold any button for greater than 2 seconds to set channel output.
Step 4. (DMX – Adjusting PWM Frequency & Dimming Type)
PWM frequency and dimming type can be adjusted for special applications.
a. Press and hold buttons 1 and 3 simultaneously for 2 seconds until 'P_c' flashes on display
(Figure 2 & Figure 6).
b. Press button 1 to choose PWM output type (Figure 7).
c. Press button 3 to choose dimming type (Figure 7).
d. Once display stops flashing, PWM and dimming are set.
Note: RGBW installations will only operate correctly with consistent color output when programed to P1 (1500Hz PWM Output)
and c2 (Linear Dimming).
