We are installing GX450 in fire trucks utilizing the DC power cord straight to the truck battery. Some trucks we have had no problems but a few we have the problem that when they turn the battery switch on for the truck, the power on the GX450 cycles. We have checked the battery for a voltage drop that would explain the power cycling but there is no voltage drop. Any suggestions?
You may set the GX450 services log = info and the linux sys = display. You should see in the log the reason the cycle takes place. Example below and the meaning.

The log show that the ignition line was pulled low which turns off the gateway as it was designed to do.

Were you able to find a solution for this?
This topic has been for a long time. Do you still face this issue on the latest ALEOS firmware?
I have them running on 4.9.5.010
The crazy thing is that out of almost 20 devices i only have two giving me this issue.
Both of these vehicles are the same make/model and year.
You can try with the latest offical FW for your GX450 (you can get FW at this page: https://source.sierrawireless.com/resources/airlink/software_downloads/gx450/gx450-firmware-list/#sthash.rR2nz8pS.dpbs). Then, you and me will find the reason if you meet this issue again.
You can try my way to find the current reason of your issue:
1, Use 1 of 2 devices having issue to attach to a vehicle not having issue.
2, Observe the result:
a, If this issue still happens, I think this issue is hardware issue. So you should contact to your distributor to change device.
b, If this issue does not happen, I think this issue is from your installation. You can try to wire the device directly to the vehicle battery (or other uninterrupted supply).
I have upgraded the firmware on all units and i will keep an eye for any changes.
Also, i have swapped the unit into different vehicles and i still get the same actions occurring.
