2.9.1 EX4 Plus: Status of the Driver’s Indicator Panel
Pushing the button in the center of the driver’s indicator panel causes an alarm
event to be recorded by the DVR. The button corresponds to Alarm 1 on the
Smart-Link alarm harness. The ring indicates the status of the DVR.
See Table 2-4.
2.10. EX4 Plus Step 9: CAN Network
The EX4 DVR has a built-in CAN interface for connecting to J1939 compliant
vehicle networks. J1939 is a Society for Automotive Engineers (SAE)
specification for network communication in a vehicle. Seon Design can factory
program the Smart-Link module to accept ten signals from the large selection
available on a vehicle. For more information, contact your sales representative at
Seon Design to discuss the CAN interface.
2.11. Step 10: TR-INR Inertia Sensor
The TR-INR inertia sensor is a programmable accelerometer and impact sensor
that can measure rapid acceleration or deceleration, abrupt movement in bus
braking or turning which can lead to complaints or injury claims. Video footage
recorded with the sensor provides valuable information for reviewing incidents
and for training purposes as well. The inertia sensor has adjustable trigger
thresholds which can be wired to trigger alarms and signals. The unit measures
4.55" × 2.55" ×1.65" (H×W×D).
Contact your sales representative at Seon Design for TR-INR inertia sensor
options.
