7.2 Vibration and Drop Test Requirements
7.2.1 Vibration
The Asset-Link has been tested to the swept sine vibration profile defined for cab
mounted equipment shown in figure A1 of SAE J1455, shown below. The test
duration was 180 minutes for each axis. The Asset-Link passed a functional test at
the conclusion of the Vibration test.
The Asset-Link was tested for a constant 2 gravities of acceleration from 18 Hz to
2000Hz in 6 logarithmic steps to determine functionality while being vibrated.
Communication with a base station on the control channel will determine
operation for digital communication. An audio 1 KHz tone will be input to the
audio input at the DB-25 Application I/O connector, and a distortion of less than
15% on a test receiver on a communications channel will be a pass criterion. A 1
KHz tone from a test transmitter will be tested on a communications channel to
produce less than 15% distortion at the audio output at the DB-25 Application I/O
connector. The TIA/EIA-690 test for 32 dB signal to noise is not applicable for
Vibration application on the Asset-Link .

7.2.2 Drop Test
Asset-Link device in the FLT-Link housing has been dropped from a height of 1
m onto a level concrete surface one time in each of the three mutually
perpendicular planes (three drops total) and been shown to be operational after all
tests.
