DN-200 GPI Trigger connection and operation
GPI Trigger cabling and circuit
The DN-200 GPI circuit runs on less than 5V
DC.
This current is supplied by the DN-200 GPI port.
You will need a pre-manufactured GPI trigger cable or, you could make your own GPI trigger using a
3.5mm stereo jack connected by 2 core cabling to a simple 'contact on closure' button or similar
trigger. Wiring from Tip and sleeve on the 3.5mm stereo jack should show roughly 3.28V DC when
plugged into the DN-200 GPI port. Jack Tip is positive(+), jack sleeve is negative(-) and ring is not
used.
SET GPI TRIGGER MODE
In the DN-200 SYSTEM SETUP menu use the option labelled SET GPI TRIGGER MODE. You can
then make a choice between the PULSE or LEVEL trigger. The selected choice is marked with an
asterisk.
PULSE trigger Record process
Using the Clip Status Display and navigation buttons select an empty DN-200 bin. Make sure the
source device is connected and working and the target file type on the DN-200 has been chosen.
Press and hold in the Record button on the front panel and then press the Play button. This should
start the record process. The button on the connected GPI cabling is then pressed forcing the unit into
record pause mode. The unit is then ready to activate record on the next press of the contact closure
button. Each time the DN-200 starts recording a new clip will be added to the bin. Press the stop
button on the front panel of the DN-200 to end recording to the bin.
LEVEL trigger Record process
Using the Clip Status Display and navigation buttons select an empty DN-200 bin. Make sure the
source device is connected and working and the target file type on the DN-200 has been chosen.
Press and hold in the Record button on the front panel and then press the Play button. This should
start the record process. The button on the connected GPI cabling is then pressed forcing the unit into
record pause mode for the length of the press. However, when the button is released the recording
process starts again. Each time the DN-200 starts recording a new clip will be added to the bin. Press
the stop button on the front panel of the DN-200 to end recording to the bin.
The contact closure button may be working in the opposite way to the type of action you want to
perform. A mechanical change to the GPI contact closure trigger should fix this. IE when pressed
down the circuit is broken and recording starts. When released the contact is made causing the pause
action.
Note: You may a have a couple of seconds footage at the beginning of the bin that you may wish to
remove later once the footage is transferred to a computer for editing.
PULSE trigger Playback process
Using the Clip Status Display and navigation buttons select a pre-recorded DN-200 bin. Make sure
the output device/monitor is connected and working with the DN-200. Press in the Play button on the
DN-200 front panel. This should start the playback. The button on the connected GPI cabling is then
pressed forcing the unit into play pause mode. The unit is then ready to playback from this point on
the next press of the contact closure button. Press the stop button on the front panel of the DN-200 to
end playback of the bin.
LEVEL trigger Playback process
Using the Clip Status Display and navigation buttons select a pre-recorded DN-200 bin. Make sure
the output device/monitor is connected and working with the DN-200. Press in the Play button on the
DN-200 front panel. This should start the playback. The button on the connected GPI cabling is then
pressed forcing the unit into play pause mode for the length of the press. However, when the button is
released the playback starts again. Press the stop button on the front panel of the DN-200 to end
playback of the bin.
