============================== requency Out
The Frequency Out protocol can be used where access to an RS232 Serial Port is not available. Three frequencies are used to represent the Color and Intensity of the LEDs. Synchronous Serial Port
The Synchronous Serial protocol is suitable when tester resources are limited or no other options are available. Daisy Chain
Multiple LED Analysers can be connected together using the Daisy Chain Connectors. Only one RS232 Serial Port or USB Port is required to connect up to 30 LED Analysers. External Trigger Input
The Feasa I provides an External Trigger Input which can be used to synchronise LED measurements with an external event such as an LED switching on.
Led Analyser Test Time
The speed of the test is dependent on the intensity of the LEDs being tested, i.e. Bright LEDs have a shorter Test Time, Dimmer LEDs have a longer Test Time. The capture (measurement) of up to 20 LEDs is done in parallel and can be achieved in times as fast as 102ms depending on the Intensity (Brightness). The data is read back from each fiber sequentially and takes approximately 5ms per fiber, for example: Ultra High Brightness LEDs Test Time
- 1 LED Capture Time is 2ms and Read Back is 5ms, Total 7ms. - 20 LEDs Capture Time is 2ms and Read Back is 100ms, Total 102ms. Dim LEDs Test Time
- 1 LED Capture Time is 650ms and Read Back is 5ms, Total 655ms. - 20 LEDs Capture Time is 650ms and Read Back is 100ms, Total 750ms. USB / RS232 Serial Port - Range Capture Times
Range Capture Time C (Auto Capture) 350ms C1 (Low Intensity) 650ms C2 (Medium Intensity) 200ms C3 (High Intensity) 22ms C4 (Super High Intensity) 4ms C5 (Ultra High Intensity) 2ms
