3.3.1 TTL Inputs (LED # 1 – 7) BNC Connectors
LED 1 through 7 TTL input controls.
3.3.1 Ring Buffer BNC Connector
Used as a strobe to step through the ring buffer.
3.3.2 USB Device Interface Connector
Provides the interface for controlling the Lambda 721 by computer via USB connection.
3.4 Operation
The arrangement of the LED cubes in the Lambda 721 allows for up to seven light sources
with differing spectral output to be combined and delivered on a common output light path.
While LED cube arrangement has many possible uses, the Lambda 721 provides a means by
which one can rapidly select any one of up to seven different LEDs as the output.
On power up, the following two screens are displayed momentarily.
Figure 3-3. Startup screen.
Figure 3-4. Product and firmware revision screen.
The next item displayed is a prompt for the last-used mode: Lambda 10, TTL, or Ring Buffer
mode. When starting the Lambda 721 for the first time, the prompt for Lambda 10 mode is
displayed as shown in the following figure.
Figure 3-5. Lambda 10 Mode prompt.
Described next is the Lambda 10 mode, followed by the TTL Mode, Ring Buffer Mode, Setup
Mode, and Demo Mode
3.1 Lambda 10 Mode
The Lambda 10 Mode is a mode in which the Lambda 721 responds to the Sutter Instrument
Lambda 10-x Series (Lambda 10-2, Lambda 10-3, Lambda 10-B, etc.) filter wheel external
commands to the control the ON/OFF state of each of the Lambda 721’s seven LEDs.
