• • • • MiniDim3/4 3/4 Channel DMX or Stand Alone LED Dimmer DMX-512 or Trim Potentiometer Adjustable Selectable Pulse Width Modulation Frequency Liquid-Tungsten© Brightness Slewing The MiniDim3 or 4 has a total system capacity of 5 amps – this capacity can be used any way you wish across the outputs, as long as you don't exceed the total available 5 amps. The controlled output to the LEDs is via an output screw barrier strip -RGB or RGBW (+) (-) labeled. The DC input is via a standard "Barrel" connector (2.1mm center pin) or a 2 conductor screw barrier strip - your choice, and DMX is using RJ45’s or 3 conductor screw barrier strip - your choice again. Reset to Factory Default modes: DMX address: 999 then press the learn switch LED Power: Externally supplied, 8-24 Volts DC. Transient voltage suppression engages at 25 volts. Leds must include current limiting resistors or constant current circuitry. ***NOTE: LED’s must be capable of operation at the fixed voltage of the DC power supply attached*** DMX-512 Is connected using the RJ-45 connectors, or (if requested) the three conductor screw down barrier strip mounted on the circuit board. ***Uses standard (not crossover) Ethernet cables*** DMX Address is selected using the 3 Rotary Switches Channel 1 will be controlled at the address shown on the rotary switches Channel 2 will be controlled at the address chosen by the rotary switches plus 1 Channel 3 will be controlled at the address chosen by the rotary switches plus 2 Channel 4 will be controlled at the address chosen by the rotary switches plus 3 RJ45 Position 001 010 100 Fuse Holder Position Note the Shaft Arrows: Address is set to 990 Selectable Modes This requires the operator to set the rotary (DMX) switches to numbers above a valid DMX address, and then press the “Learn” momentary switch to store the new operational mode into non-volatile memory. From that point on, the selected modes will be in effect - unless changed manually. After programming the desired modes, choose a valid DMX address (001-512) or 000 to operate. ***The momentary switch is accessible via a small hole in the sheet metal cover, between the output connections and the DMX selector switches (near the chassis wall).*** Liquid-Tungsten© Brightness Slew Changing brightness quickly may not be the desired look. Liquid Tungsten is a software package that smoothes out the DMX steps, to make a LED act as if it were a quartz lamp. Liquid Tungsten© Brightness Slew Rate modes: DMX address: 800 Fastest DMX address: 801 *(Default) DMX address: 802 DMX address: 803 DMX address: 804 Slowest Pulse Width Modulation Base Frequency modes: DMX address: 901 DMX address: 902 DMX address: 903 DMX address: 904 250 HZ 500 HZ 1000 HZ *(Default) 4000 HZ Channel to DMX Address modes: DMX address: 701 *(Default) Ch-1 is controlled at the DMX address chosen, Ch-2 is controlled at the address chosen + 1, Ch-3 is controlled at the address chosen + 2, and Ch-4 is controlled at the address chosen + 3 (MiniDim4) DMX address: 702 All three/four outputs are controlled at the DMX address chosen. DMX address: 703 Ch-1 is at the DMX address, Ch-2 is at the next address, (Ch-3 & Ch-4) are at the next address. DMX address: 704 USITT DMX-512 (16-bit resolution) Two DMX addresses used per channel. Ch-1 is at the first two DMX addresses, Ch-2 is at the next two DMX addresses, Ch-3 is at the next two DMX addresses, Ch-4 is at the next two DMX addresses. (MiniDim4) ***Note: To give the most user control, Liquid Tungsten is disabled in this mode*** Digital Output modes: Dim or Non-Dim This changes the output from Pulse-Width-Modulation (PWM), to full On or Off (Digital). This can be used to drive an external relay or similar device. DMX data below 50% is off, above 50% is on. DMX address: 731 DMX address: 732 DMX address: 733 DMX address: 734 Ch-1 to Digital Ch-2 to Digital Ch-3 to Digital Ch-4 to Digital (MiniDim4) DMX address: 721 DMX address: 722 DMX address: 723 DMX address: 723 Ch-1 to PWM *(Default) Ch-2 to PWM *(Default) Ch-3 to PWM *(Default) Ch-4 to PWM *(Default) (MiniDim4) DMX indicator LED (position) 4 3 2 1 Fuse Holder (position) Stand Alone / Master With the rotary switch’s at DMX address zero (0 0 0), the three/four trim pots control the level of their corresponding output channel. Status Led The “DMX Status indicator LED” shines through an opening in the sheet metal located behind the RJ-45(s)/3-pin screw barrier strip. The green LED lights when DMX is present. ***Note: this does not confirm the quality of the DMX signal*** Demo modes: (subject to change per requests) No “Learn” switch press is required to set a Demo mode. Simply set the DMX address to go into Demo mode you wish. Ch-4 is only available on the MiniDim4 Demo mode 1. Ch-1, 2, 3, 4 Overlapped Smooth Up-Down Chase, all up, then down, Repeat. DMX address: 990 DMX address: 991 Demo mode 1, Speed is set by Potentiometer #2. Demo mode 1, Fixed speed. Demo mode 2. Color dissolve, Trim Pot #3 controls the dimming of Channel #4’s output DMX address: 992 DMX address: 993 Trim Pot #2 adjustable, faster speeds. Trim Pot #2 adjustable, slower speeds Demo mode 3. Channel Step, Trim Pot #2 controls the speed of stepping DMX address: 994 DMX address: 995 CH1 > CH2 > CH3 > CH4 then start again CH4 > CH3 > CH2 > CH1 then start again Demo mode 4. Up/Down bar-graph, Trim Pot #2 controls the speed of stepping DMX address: 996 DMX address: 997 CH1 > CH1+CH2 > CH1+CH2+CH3 > CH1+CH2+ CH3+CH4 then back out Same as 996 except at a non-adjustable speed Demo mode 5. Snake Chase, Trim Pot #2 controls the speed of stepping DMX address: 998 Black > CH1 > CH1+CH2 > CH1+CH2+CH3 > CH1+CH2+CH3+CH4 > CH2+CH3+CH4 > CH3+CH4 > CH4 > [Start again at Black] WARNING Do not supply less than 8 volts DC or more than 24 volts DC. Higher voltage will cause damage to the Transient Voltage Suppression. Using voltages outside 8-24 Volts DC will void the warranty. Operating Power Derived from external DC power supply. Control circuitry uses approximately 100ma. Fuse The DC power supply input is fused at a Maximum of 7.5 AMP MTA (automotive style fuse). MiniDim3/4s are shipped with a MTA 5 fuse installed Wiring LED power output connections are made using captive screw terminals. The circuit board has labels defining the input and outputs, including polarity RJ-45 connectors Pin-1 DMX (+) Pin-2 DMX (-) Pins 7 & 8 DMX GND Pins 3, 4, 5 & 6 are pass through.
