Shooting Tips and Tricks
Fault: No GPS Reported:
Diagnostics:
Is the GPS LED on the UMD Solid Red? If not then the GPS Engine inside the UMD is unable to get sufficient or
any GPS signal
Actions:
Move the asset to a position where the GPS antenna has clear view of the sky
Check the connector on the UMD, the GPS Antenna has a small gold connector (SMA) which connects to the
panel connector on the UMD labeled GPS. Make certain it is finger tight.
Note that the RF Panel Connector is the same connector type but labeled RF
Try a second GPS antenna if you have one, if not contact Cooltrax Support to arrange for a spare antenna.
Fault: The UMD is not reporting to the web applications
–
essentially the unit is offline.
Diagnostics:
How are the IP and the Signal Red LED’s behaving?
For consistent communications with the web application the GSM or 3G modem within the UMD must first
register with the Telco Provider and then become IP active - ready to communicate with the website. When
there is data to be sent, the modem connects to the website allowing a bi-directional transfer to occur
between the modem and the website via the cellular network
The Red Signal LED will flash slow, fast or solid depending upon the signal strength and the IP LED will slow at
first and then flash fast.
Note: Signal LED Flash Legend

Actions:

Check the connector on the UMD, the GSM/3G Antenna has a larger silver connector (TNC) which connects to
the panel connector on the UMD labeled GSM/3G. Make certain it is finger tight.
Try a second GSM/3G antenna if available, if not contact Cooltrax Support to arrange for a spare antenna.
