The Digi m10 has been designed and tested to operate under the conditions shown in Table 9
Table 9: Operating Conditions
Operating Temperature Humidity Cycle Comments
-40 °F to +185 °F (-40 °C to
+85 °C)
SAE J1455 4.2.3 , Fig 4a , 8h,
3 cycles (90% RH)
For 24 hours with a 12 V
supply
3.1.4 Storage Temperature
The Digi m10 can be stored for extended periods from -58 °F to +185 °F (-50 °C to +85 °C). It
has been subjected to the upper and lower temperature limits for 24 hours each and then
checked for stability.
3.1.5 Operational Shock
The Digi m10 remains structurally intact and operational after the drop test (as defined in
SAEJ1455) from 1.22 m onto each of its corners and its face.
The Digi m10 also meets the MIL-STD-810E, Method 516.4, Procedure I as defined in the
ORBCOMM Subscriber Communicator (SC) Standards and Specifications.
The Digi m10 can withstand 20 g sawtooth shock, 11 ms duration, 3 times along each of 3
orthogonal axes; as per MIL-STD-810E, Method 516.4 Procedure I.
3.1.6 Operational Vibration
The Digi m10 meets the MIL-STD-810E, Method 514.4 and ETSI 300 721 as defined in the
ORBCOMM Subscriber Communicator (SC) Standards and Specifications.
The Digi m10 has also been tested according to SAEJ1455 (as per the practices for heavy duty
trucks), which specifies that the vibration profile for CAB-mounted vibration PSD for Vertical Axis
(Figure 6, 1.04 g rms) is to be tested in three mutually perpendicular planes and that a sweep rate
of ½ octave per minute is to be used.
