Hardware I Introduction
I Introduction
USB-DMX interfaces 512 channels
The USB standard defines a new type of serial-communication as well as a new type of connector. This
standard was introduced in 1997 and has been spreading ever since 1999.
It offers many advantages in comparison with former standards. For instance, it allows devices to be
directly powered via the USB port as well the simultaneous use of several devices at once. Plug and
play is also made possible.
The USB-DMX interface is a world's first innovation. It thoroughly respects the USB protocol
specification and DMX512 for output. It is directly powered via the USB port and controls all 512
potential channels of a DMX line. If the 512 channels are not sufficient, some software can run up to 10
USB interfaces simultaneously, i.e. 5,120 channels altogether.

Hardware II Installing the USB drivers
II Installing the USB drivers
Although Microsoft does not numerically register this driver, there is no risk of
incompatibility. Click "Next" and carry on the driver installation.
That's it, you are away ! Your USB-DMX is now operational !
The USB interface is set and ready to use. When using one for the first time, it is
necessary that the USB drivers should be installed. Actually, when first installing them, the files required
to use the interface will be installed inside your PC, whether using a laptop or a desktop computer.
In order to install USB interface, just connect it to your PC even if it is switched on. Your computer will
automatically detect any new device and you will be prompted to load a driver for it (via a Window
wizard).

Then insert the CDrom into your PC and click on Next. Windows will find the appropriate
driver.

· The yellow Led (in the middle) indicate that the interface is properly-powered.
· The red Led situated by the "DMX" connector blinks to indicate that the DMX signal is being sent. No
blinking corresponds to interface-failure.
· The green Led by the "USB" connector should blink rapidly when the interface is controlled by a
software. In stand alone mode, this green led blinks several times to indicate active scene number.

IV Memory capacity in stand alone mode
The stand alone memory capacity depends on the number of channels. More channels you use, less
steps are available.
See the following table to know the number of steps available.
USB version
20 channels 2386 5629
100 channels 549 1297
248 channels 225 534
512 channels X 259

V External power
Here are the characteristics of the external power supply for the "stand alone" interfaces:
Voltage:
between 9V and 12V DC
Intensity:
300mA or more
Polarity:
+ in the centre
We advise a power supply respecting the CE and UL norms.

VI HE10 connector
It enables to connect 8 ports. No power is needed, you only have to make a temporary contact between
the ground (pin 2) and one of the 8 ports (pins 1,3,4,5,6,7,8,9). If 8 contacts are not enough, you can
use several ports simultaneously to get up to 255 possibilities by using binary combination.
External Connector Pin Assignment:
Pin 1: Port 8
Pin 2: Ground
Pin 3: Port 7
Pin 4: Port 6
Pin 5: Port 5
Pin 6: Port 4
Pin 7: Port 3
Pin 8: Port 2
