Operation - Martin LC 2140 User Manual

Operation

If the system is correctly set up, operation is simply a question of displaying video from the media server or
other DVI video source.
During operation, four LED indicators on the connections panel give information about the status of the
panel and the video signal:
• The Power LED lights when power is applied to the panel.
• The Pulse LED flashes when the system controller is running. The flash rate is 1/16 of the signal
frequency (at 50 Hz, 20 flashes take approx. 12 seconds). The LED flashes slowly when there is no
signal.
• The Error LED should not light during normal operation. It lights constantly if there is a fault in the video
signal or panel. The Error LED has a secondary function: it flashes when there is communication
between a PC and the panel.
• The DVI LED lights when the panel is receiving a valid DVI signal.
When repacking panels in a Martin flightcase after operation, follow carefully the instructions in "Packing
panels in the flightcase" on page 9.
