3.2 Installation
AURA FDM light engines incorporate fan-assisted air cooling. When positioning the AURA for use, place the unit on a
hard surface and avoid blocking or restricting airflow at the air intake (side panel) and exhaust ports (underside).
Restricting the airflow will cause the unit to operate at elevated temperatures and will result in decreased operating
lifespan and/or premature failure.
Connect the DC power supply to the DC power input on the rear panel of the light engine (Figure 2) then connect the DC
supply to an AC wall outlet via the AC power cord. The power indicator LED recessed in the top panel of the light engine
(Figure 2) should now be lit.
3.3 Serial Control
Connect a USB A-to-RS-232 cable (Lumencor part number 29-10011) between the computer and the RS-232 serial
port on the AURA (Figure 2). Successful connection is indicated by the appearance of “USB Serial Port (COM #)” under
the “Ports (COM &LPT)” tab in the Windows Device Manager. If the virtual COM port (VCP) is not registered by the
operating system, download and install the VCP driver from
http://lumencor.com/resources/documentation-software/
.
Serial commands are provided for independently turning each color channel on or off and for independently setting the
output intensity of each color channel. A summary of the serial command strings is available on request from
Lumencor’s technical support department via the contact channels described in Section 7.
3.4 TTL Control
The TTL interface provides users with a faster method of switching color channel outputs on and off. Individual TTL lines
are provided for each color channel. These can be conveniently addressed using an accessory BNC breakout cable
(Lumencor part number 29-10015 or 29-10080) connected to the rear panel DB15 TTL port. Note that TTL and serial
on/off commands have a logical OR relationship. Therefore serial interface on/off controls must be set in the “OFF” state
