Example QC screen:
Auxilliary socket
The socket is for NETmc Marine Engineer use only.
Trigger Connector
This socket is used to link the recorder to an external trigger source, so that it may automatically
start and stop.
A plug to be used for connecting to the external source is supplied with the unit:
2-way COMBICON terminal block connector (RS part no.: 189-6486)
When 12v is applied across the trigger input (NOT polarity sensitive) the recorder will start
recording. When the 12v is removed, the recorder will stop recording.
Once recording is activated by the trigger, it can only be stopped via the external trigger – i.e. the
front panel controls are disabled.
Typical remote trigger examples are:
•
Record switch on control desk
•
Off-deck microswitch for ROV / dive bell
•
Feed from main system switchboard (recording starts when vehicle power on.)
It is important to plug in all video and audio input / playback /
pass-through connections before switching on the 73fifty.
