Signal Signals 1 through 5 are hardwired inputs, received through the signal
harness (LT/left turn signal - black wire, STP/stop - green wire, BRK/
brake - red wire, WRN/warning lights - brown wire, and RT/right turn
signal - white wire). When these triggers are active, they generate
signals and display associated labels during video playback.
n/a
Label You can edit the on-screen display text label (maximum 3 characters)
to describe each signal as desired.
For instructions on using the mouse to enter data, see DH4 Operation:
Using On-screen Keyboards.
Labels 1 through 5: [LT],
[STP], [BRK], [WRN], [RT].
Labels 6 through 10: [S06],
[S07], [S08], [S09], [S10]
Level Control how the signal senses activation: choose Active H (high) if the
circuit rests at 0 VDC and goes to 12 VDC when active; choose Active L
(low) if the circuit rests at 12 VDC and drops to 0 when active.
[Active H], Active L
Alarm Select the alarm number if the signal is also used to trigger an alarm.
The alarm's input must also be set up in the Alarms menu.
Note: assigning alarms to the default signals 1 through 5 is generally
not recommended, since these would be continually triggered by
normal vehicle operation.
