3.3 Connectors
3.3.1 Liquid Light Guide Connector
Provides the interface between the high-power LED (mounted inside the cabinet immediately
behind the connector) and the liquid light guide for which this connector is designed to
accommodate.
3.3.2 ANALOG-IN BNC Connector
An analog input from 0-5v controls intensity through PWM dimming.
3.3.3 TTL-IN BNC Connector
Allows for the control of the LED like a shutter. When the LED switch is in the TTL
position, TTL-IN is gated low, which keeps the LED in the OFF state. Once TTL-IN receives
a high signal, the LED turns on for the duration that TTL-IN is held high.
3.3.4 TTL-OUT BNC Connector
Outputs a triggering signal for external software. When the LED is off, TTL-OUT is high;
when the LED is on, TTL-OUT is held low the duration that the LED is on.
3.4 Fault Conditions
The Lambda HPX-L5 is equipped with a temperature monitor to maximize the life of the
LED. Should a fault occur, the screen turns red and the lamp is automatically turned off. If
the screen turns red, and the text is unchanged, the LED temperature has exceeded its safe
operating temperature. If the corner of the screen displays “Fan” when turning red, it means
that the fan has failed, and is no longer turning.
