Mechanical Structures and Installations

Wiring Diagram

Note

1. An DMX signal amplier is needed if more than 32 decoders are connected, or use overlong signal line, signal amplication should not be more than 5 times continuously.
2. If the recoil effect occurs because of longer signal line or bad line quality, please try to connect 0.25W 90-120Ω terminal resistor at the end of each line.

Operation

System parameter setting

• Long press M and ◀ key for 2s, prepare for setup system parameter: decode mode, grey level, output PWM frequence, output brightness curve, default output level, automatic blank screen.short press M key to switch six item.
• Decode mode: short press ◀ key to switch 1-channel decode(”d-01″), 3-channeldecode(”d-03″) , 6- channel decode(”d-06″) or 24-channel decode(”d-24″).When set as 1 channel decode,
  and 24 channel output the same brightness of this DMX address.
• Grey level: short press ◀ or ▶ key to switch 8bit(”b-08″) or 16 bit(”b-16″). choose 16 bit if the DMX master support 16 bit.
• Output PWM frequence: short press ◀ or ▶ key to switch 500Hz(”F05″), 1000Hz(”F010″), 2000Hz(”F020″), 4000Hz(”F040″), 8000Hz(”F080″), 16000Hz(”F160“) or 32000Hz(”F320“).
• Higher PWM frequency, will cause lower output current, higher power noise, but more suitable for camera(No fickers for video).
• When setting the PWM frequency > 8000Hz, the output current per channel needs to be reduced (24x2A@12-24V at 16000H or 32000Hz).
• Output brightness curve: short press ◀ or ▶ key to switch linear curve(”C–L“) or logarithmic curve(”C–E”).
• Default output level: set output level when no DMX input signal. short press ◀ or ▶ key to switch maintain DMX output(”d- -”) or output default level (”d00″ to “dFF”, 0-100%), long press ◀ or ▶ key to change output default level.
• Automatic blank screen: short press ◀ or ▶ key to switch enable (”bon”) or disable(”boFF”)automatic blank screen.
• Long press M key for 2s or timeout 10s, quit system parameter setting.

Note: In addition to manual button operation settings, the above system parameters can also be set by RDM function.

DMX mode

• Short press M key, when display A001~A512, enter DMX mode.
• Press ◀ or ▶ key to change DMX decode start address(001~512), long press for fast adjustment.
• If there is a DMX signal input, will enter DMX mode automatically.
• DMX Dimming: Each D24 DMX decoder occupy 24 DMX address when connecting the DMX console.

For example, the defaulted start address is 1, their corresponding relationship in the form:

DMX Console	DMX Decoder Output
CH1 0-255	CH1 PWM 0-100% (LED 1#R)
CH2 0-255	CH2 PWM 0-100% (LED 1#G)
CH3 0-255	CH3 PWM 0-100% (LED 1#B)
CH24 0-255	CH24 PWM 0-100% (LED 8#B)

Stand-alone RGB mode

• Short press M key, when display P–1~P–4, enter stand-alone RGB mode.
• Press ◀ or ▶ key to change dynamic mode number(P–1~P–4).
• Each mode can adjust speed and brightness.
• Long press M key for 2s, prepare for setup mode speed, brightness.
• Short press M key to switch two item.
• Press ◀ or ▶ key to setup value of each item.
• Mode speed: 1-10 level speed(SP-1, SP-9, SP-F).
• Mode brightness: 1-10 level brightness(br-1, br-9, br-F).
• Long press M key for 2s, or timeout 10s, quit setting.
• Enter stand-alone RGB mode only when DMX signal is disconnected or lost.

RGB change mode list

No.	Name
P–1	White forward jump chase
P–2	White forward smooth float
P–3	Red, yellow, green, cyan ,blue, purple forward jump chase
P–4	Red, yellow, green ,cyan, blue ,purple forward smooth float

Stand-alone dimmer mode

• Short press M key, when display L–1~L–8, enter stand-alone dimmer mode.
• Press ◀ or ▶ key to change dimmer mode number(L–1~L–8).
• Each dimmer mode can adjust each channel brightness independently.
• Long press M key for 2s, prepare for setup 24 channels brightness.
• Short press M key to switch 24 channels(0100~01FF, 0200~02FF, 0300~03FF, … , 2400~24FF). Press ◀ or ▶ key to setup brightness value of each channel.
• Long press M key for 2s, or timeout 10s, quit setting.
• Enter stand-alone dimmer mode only when DMX signal is disconnected or lost.

Restore factory default parameter

• Long press ◀ and ▶ key for 2s, restore factory default parameter, display”RES”.
• Factory default parameter: DMX decode mode, DMX decode start address is 1, 24 channel decode, 8 bit grey level, 2000Hz PWM frequence output, logarithmic brightness curve, output 100% level when no DMX input, RGB mode number is 1, dimmer mode number is 1, disable automatic blank screen.

Malfunctions Analysis & Troubleshooting

Malfunctions	Causes	Troubleshooting
No light	No power. Wrong connection or insecure.	Check the power. Check the connection.
Wrong color	Wrong connection of R/G/B wires. DMX decode address error.	Reconnect R/G/B wires. Set correct decode address.
Uneven intensity between front and rear, with voltage drop	Output cable is too long. Wire diameter is too small. Overload beyond power supply capability. Overload beyond controller capability.	Reduce cable or loop supply. Change wider wire. Replace higher power supply. Add power repeater.

FAQ

Do I need a signal amplifier for more than 32 decoders?

An amplifier is required if connecting more than 32 decoders. Avoid signal amplification exceeding 5 times continuously.

How to address recoil effects due to long signal lines?

To address recoil effects, connect a 0.25W 90-120 terminal resistor at the end of each line affected by longer signal lines or poor quality.
