DVR-50-TH Wiring Diagram
Trigger IN 1- 8 can be a high or low trigger value which is configured in the menu of the DVR-50(G).
Trigger Out 1 and 2 can be used to trigger external devices (such as a telematics device) when any trigger
input is activated. This is again configurable in the DVR-50(G) menu.
Speed input can be used to record speed information of the vehicle onto the recording captured on the
DVR-50(G). It should be connected to the analog speed output wire on the vehicle (often found behind the
radio or instrument cluster).
RS232 output can be used to send and receive data from external devices.
The external mic input can be used to record separate audio to that of the mic normally housed in the
cameras.
