GPI Control

GPI Trigger cabling and circuit

The recorder has a GPI socket on its rear panel. The GPI circuit runs on less than 5V DC. This power
is supplied by the recorders GPI port. You will need to manufacture a GPI trigger cable using a
3.5mm stereo jack connected by two 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 voltage when plugged into
the recorder's GPI port. Jack Tip is positive(+), jack sleeve is negative(-) and ring is not used.
Depending on the settings of the recorder and the GPI menu option this unit can be configured to
Record / Record Pause or Play / Play Pause with the current video BIN.
If making a recording first set up the recorder in the normal way, refer to pages 11 to 22.
If playing back a file select the required video BIN on the LCD Clip Status Display. Now enter the
Menu again and go to the SYSTEM SETUP menu and choose the SET GPI TRIGGER MODE.

SET GPI TRIGGER MODE

In the 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 soft keys select an empty video BIN. Make sure the source device
is connected and working and the target file type on the recorder 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 recorder starts recording a new clip will be added to the bin [ Max 99 CLIPS per BIN ]. Press
the stop button on the front panel of the recorder to end the recording process.

LEVEL trigger Record process

Using the Clip Status Display and soft keys select an empty video BIN. Make sure the source device
is connected and working and the target file type on the recorder 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 recorder starts recording a new clip will be added to the bin [ Max 99 CLIPS per
BIN ]. Press the stop button on the front panel of the recorder to end the recording process.
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. ( Example: 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.
