2) When not in use, the data collection should be stopped, and the units switched off. 3) The transmitters should not be directed upwards, only towards the investigation body. Receivers from ImpulseRadar are passive digital devices, requiring no certifications (FCC part 15.103c). Information to users in the US Operation of this device is restricted to law enforcement, fire and rescue officials, scientific research institutes, commercial mining companies and construction companies.
Both trig inputs require some drive capabilities on the trig-unit end, by using receivers from ImpulseRadar, proper drive current is guaranteed. If other trig devices are uses, please refer to further information under the Operations section. Note that both trig inputs are identical, active high-signals on both will cause the unit to output an impulse of electromagnetic energy, however, trigs must always be separated by ate least 3.2us, stipulated by the maximum trig-rate.
PC by means of an Ethernet switch, in order to gather data from both simultaneously. Note that shared operation can only be done with receivers from ImpulseRadar, as otherwise, the trig- rate and separation in time of the trig signals may not be guaranteed.
