VENTIDRIVE
24 CHANNEL LED DIMMER
The VentiDrive is a 24 channel LED dimmer with 1200 watts of output capacity.
Its design allows for fast Plug’n’Play connectivity and allows you to be up and running in no time. It features precision dimming from 0 – 100%, 8-bit or 16-bit modes, PWM frequency adjustment from 500Hz to 35kHz, full manual control, and dimming curve adjustments.
1. Brought back Terminal Block DMX I/O 2. PWM Frequency adjustable via RDM Each channel has a maximum power output of 4A (96 watts @ 24VDC or 48 Watts @ 12VDC) to a maximum of 8.3A (200 watts @24VDC or 16A @ 12VDC). The VentiDrive is available in either 12VDC or 24VDC models. Its rugged chassis is capable of being hung via clamps, mounted in a rack, stacked on top of each other, or screwed into a wall. This allows it to be placed in almost any location. Industry-standard 5-position terminal plugs allow for universal connectivity to as many LED products as possible. TRUE1 connectors & auto-switching internal power supplies allow for power input from 90 – 250VAC. Whisper-quiet 16dB fans keep the unit cool in any location and to top it all off the VentiDrive can be remotely addressed via RDM. Delivering 50A @ 24VDC or 100A @ 12VDC this is the most powerful LED dimmer on the market!

WIRING DIAGRAM
Master Mode
Decoder Mode
Prior to adjusting any values please decide if you would like to operate in DMX mode or Manual mode. DMX mode is run 1 and Manual mode is run 2. DMX mode operates in conjunction with a device that outputs DMX. Please connect the device via the XLR ports. In Manual mode, the unit can be controlled via the onboard LCD read-out. Any settings manually selected will also output DMX values downstream to other connected devices. To switch between run1 and run2 mode you must select the mode and then you will see the new set of menu options. Older firmware versions require the unit be powered off and turned back on again in order to switch between run1 and run2 modes
DMX Mode (Decoder Mode) 
Using the “Up/DOWN” buttons you can cycle through the following menus.
DMX address 1 to 507, default set to 001. The decimal after the “A” indicates receiving a DMX signal.
DMX channel quantity, a default set to CH24
Bit resolution 8bit/16bit, default set to 16bit
PWM frequency 500Hz to 35KHz, default set to 10kHz. For most camera settings please set it to 10kHz.
Dimming gamma curve value, a default set to1.5
Decoding mode, a default set to dP1.1
Switch between DMX Mode and Manual Mode. Power cycle the unit to complete the mode change.
Manual Mode (Master Mode) 
To enter Manual Mode use the “UP/DOWN” and set to “ ” press “ENTER” then with the “UP” button set to “ 
”. Press “BACK” to confirm.
The following menu will appear.
Chasing effects. 4 effets to choose from.
Program speed 1 to 9
Manual control over channels 1 to 24 from 00 to FL Switch between DMX Mode and Manual Mode. Power cycle the unit to complete the mode change. Newer firmware versions do not require a power cycle.
- Set DMX Address (Can be adjusted remotely via RDM)
To set the DMX address select menu
, press “ENTER” the display will flash.
Press “UP/DOWN” to set the DMX address. Press “BACK” to confirm. - Set Channel Quantity (DMX Footprint)
Select menu CH xx, press “ENTER” the display will flash. Press “UP/DOWN” and set the DMX channel quantity. Press “BACK” to confirm.
Example: DMX address is set to 001.
CH01 : Footprint DMX = 1 (One DMX address for all the output channels)
CH04 : Footprint DMX = 4 (Four DMX addresses 001, 002, 003, 004, etc. grouped together)
CH24 : Footprint DMX = 24 (24 DMX addresses. Factory Default. Output 1-24 is address 001-024 respectively.) - Resolution

16 = 16KHz
18 = 18KHz20 = 20KHz
25 = 25KHz
30 = 30KHz35 = 35KHz - Gamma Curve Value
Select menu
, press “ENTER” the display will flash.
Press “UP/DOWN” to choose 0.1 to 9.9. Press “BACK” to confirm.
*Gamma adjusts the dimming curve of the unit so you can have an extremely high-resolution low end or an extremely high-resolution high end. - RDM Functions
