3.3.3 Ethernet Connection and Control GUI
The Web GUI provides a quick and easy way to control the light engine, providing the ability to turn
each source on/o
ff
, adjust the power of each source independently from o
ff
to full power (Figure 5,
left). The GUI also tracks the total on time and the power sensor readings. To set up the Web GUI,
follow the follow protocol below:
1. Go to Start menu > Control Panel > Network & Internet and/ or Network & Sharing Center
2. Click Change Adapter Settings
3. Right-click on Local Area Connection
4. Click on Properties (in pop-up)
5. Select Internet Protocol Version 4 (TCP/IPv4)
6. Click Properties button
7. Use the following IP addresses:
•
IP Address: 192.168.201.201
•
Subnet Mask: 255.255.255.0
•
Default gate way and DNS Server are OK to leave blank
8. Connect the RJ45 cable (supplied with the light engine) between the LAN port on the light engine
and an Ethernet port on the computer.
9. Type the Light Engine IP address (Figure 3) into any web browser address bar to access the
resident control GUI. The factory default IP address is 192.168.201.200.
Output power regulation allows users to eliminate variations in light output due to temperature
fluctuations and other environmental factors in photometric and quantitative imaging applications
where reproducibility and accuracy are essential. To use power regulation, a desired power reference
value in milliwatts is entered in the onboard control GUI. To activate power regulation, simply click
the padlock icon next to the reference power value. Gray shading of the padlock icon and the
reference power value shows that power regulation is active for the selected output channel. When
power regulation is active, the intensity setting for the channel is controlled by the onboard
microprocessor, based on feedback from the light engine’s reference photodiode array. The
microprocessor continuously adjusts the intensity setting so that the output power matches the
power reference value set by the user.
3.3.4 Control via Serial ports
AURA Light Engine have two serial ports, labeled USB and RS-232 (Figure 3), which can be set to
receive either LEGACY or STANDARD mode commands. Connection to the computer requires a
USB-A-to-USB B cable (29-10058) or USB-to-RS-232 cable (29-10011). LEGACY commands are
limited to controlling on/o
ff
switching and intensity adjustment of individual color channels. Only one
of the two ports can be set to LEGACY mode at one time. The STANDARD mode command set
gives access to an extensive panel of operating status reports and configuration settings in addition
