![]() I've just purchased an Enttec DMX USB Pro Mk2 to run alongside my MagicQ software on my new MacBook Pro.D+ is connected to INT0 and is used by the usb-driver, D- on INT1 permits to check regularly if the usb bus is still alive, put the processor into powersave mode when its not, and wake it up again on any bus activity. ![]() There is a 5pin XLR connector for the DMX and the cable of a dead mouse wired directly to the board for USB.The design is GPL (you can build your own!) and is quite basic, and does not offer any protection for your equipment. It works quite well, but if for example your PC froze for a second, so would the DMX. ![]() The OpenDMX USB is based on a FT232BM chip, a USB to Serial converter produced by FTDI.The widget is capable of DMX transmission and reception, but is totally reliant on the CPU to produce (or capture) the DMX signal, so this type of device is called 'unbuffered'.
