The device is powered entirely through the vehicle’s OBDII connector and will operate over a
voltage range of +9VDC to +12 VDC. The device will turn-off (sleep mode) approximately 60
seconds after the vehicle is turned off, thereby not imposing any load on the vehicle’s battery
and electrical system. The device interrogates the ECM for data and does not
modify/change any vehicle parameters.
The device is configured using the memory card that contains the various system
configuration parameters. The memory card will store real-time vehicle performance data
that can be later retrieved using a PC and the accompanying software application utility.
The device typically becomes active within 7 seconds after the vehicle engine is turned on.
OttoView™-CD will power down 60 seconds after the vehicle engine is stopped, or after a set
time duration that is defined through the device configuration setting using the software
application utility.
NOTE: During the last 3 seconds of a trip, and for three (3) seconds immediately after the
device powers down, the OttoView™-CD device will not respond to the engine ECM. If the
vehicle’s ignition is turned back on during this six (6) second period, the OttoView™-CD
device will not power on until after the next trip.
