ELM303 Camcorder Time-Lapse Control Data sheet
●The ELM303 is a specialized circuit for creating time-lapse videos on suitably equipped camcorders.The camcorder to be controlled must have a ControlL (LANC) port, and also be capable of responding to power control signals.This is usually only available with the mini DIN connectors, and not the 2.5mm stereo plug interfaces.
●The ELM303 provides intervals of 10 minutes to 24 hours between recordings, without requiring anyexternal timing components.Recording durations of either 1 second or 10 seconds is also selectable.
●One additional feature allows manually triggered recordings to be initiated when all three interval inputs are at a low level. Recording will begin immediately and will continue as long as the inputs remain low.This combination is fully debounced, simplifying the interface to mechanical switches.
●The ELM303 has been‘hard–coded’to send the Control L hex command‘33’ (word 1) to device‘18’(word 0), and cannot be modified. Be sure to verify that these are appropriate for your camera beforecommitting to any designs.
■Features
●Delays of 10 minutes to 24 hours with no external timing components
●Recording durations of 1 or 10 seconds
●Low power CMOS design - typically 1mA at 5V
●Security feature allows on demand recording
●Initial recording after 1 minute to verify system operation and connections
●Pulsed power output to control camera power
