Juno JFX™ Series DMX 4-Channel Decoder

IMPORTANT SAFETY INSTRUCTIONS

• Read all these instructions before starting installation.
• Keep these instructions in a safe place for future reference.
• Only qualified electricians in accordance with local codes should install these fixtures.
• De-energize electrical circuit at circuit breaker prior to installation process. Always ensure power is off before making any changes to installation.
• Do not connect directly to high voltage power. Must be connected to approved Class 2 LED driver.
• Do not disassemble or modify these products beyond instructions or warranty will be voided.
• Only install in an Indoor dry location.
• Ensure wire gauge used from driver to decoder and decoder to LED strip is sufficient to maintain a voltage drop under 3% (See Spec Sheet for details).

Maximum of 10x DMX Decoders may be connected via RJ45 DMX connection ports (DMX Output). DMX signal may be extended further by installing a DMX 8-way splitter after the 10th DMX Decoder.

Step 1. (DMX - System Installation)

Once mounting locations are determined for the LED driver junction box, DMX Decoder, and LED strips refer to DMX wiring guide (Figure 1). CAT5 / RJ45 data cables are recommended for transmitting DMX-512 signal. XLR-3 cables may be installed but require an additional adapter for connecting to DMX decoder.

Figure 1: DMX Wiring Diagram

Diagram shows a 120V supply connected to a Class 2 LED Driver within a junction box. The LED driver output (Red +, Black -) connects to the DMX Decoder's DC Input (V+, GND). The DMX Decoder's DMX Input (Data IN, GND) connects to a DMX Controller via CAT5/RJ45 cable. The DMX Decoder's DMX Output (Data OUT, GND) connects to an LED Strip (RGBW) via CAT5/RJ45 cable. The LED strip connections are shown as Red (CH1), Green (CH2), Blue (CH3), and White (CH4).

Step 2a. (DMX - Standard Operation)

Adjust the following settings using the 3 buttons on the DMX start channel to adjust the values of the DMX address. The decoder will control up to 512 channels (Figure 2).

1. To set the DMX address, press and hold 'button 1' for 2 seconds until numbers on the display flash.
2. Select an address based on the functionality of the master DMX controller. Once an address is selected, the remaining 3 channels will be utilized digitally. Ex. If decoder is addressed to 001 on the display, then CH1-001, CH2 – 002, CH3 – 003, CH4 – 004.
3. Once display stops flashing, DMX address is set.

Figure 2: DMX Start Channel Display

The display shows three digits, with buttons labeled 1, 2, and 3 below them. The display indicates the current DMX address being set.

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)

1. Press and hold buttons 2 and 3 simultaneously for 2 seconds until ‘cH' flashes on the display (Figure 2 & Figure 4).
2. Press button 1 to choose 1, 2, 3, or 4 channel outputs (Figure 5).
3. 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.

1. Press and hold buttons 1 and 3 simultaneously for 2 seconds until 'P_c' flashes on display (Figure 2 & Figure 6).
2. Press button 1 to choose PWM output type (Figure 7).
3. Press button 3 to choose dimming type (Figure 7).
4. Once display stops flashing, PWM and dimming are set.

Note: RGBW installations will only operate correctly with consistent color output when programmed to P1 (1500Hz PWM Output) and c2 (Linear Dimming).
