Is there a document where I can find more information about Turn GPS receiver off and Turn external device off?

These settings allow you to set a time from MyGeotab >> Assets >> Devices and Configuration for the GPS receiver to remain active after the ignition is turned off, whether it's 1 hour, 10 minutes, 4 hours, etc.

Based on this, do you know how much power it consumes during that time period? Or is there a document that explains this in more detail?

I looked in the product guide and the firmware guide but didn't find any information.

Thank you😁

Hello @PauletteGonzalez-1884 ,

Thank you for asking your question in our community. I found a couple things that will be helpful but no all inclusive document. Both of these options are primarily used together with IOX-OUTPUT but it does have other use cases. I have seen Turn GPS receiver off used to allow the GO device to maintain and / or acquire a location quicker. In situations where companies make short but frequent stops. As for for the Turn external devices off option this primarily used for IOX-OUTPUT but there are also other IOX use cases. I will share a little about it: Relay control

IOX-OUTPUT is capable of receiving ON/OFF messages from MyGeotab through the GO device to turn an external device on and off. Once a command is sent down to the device (using a custom MyGeotab Add-In or a specific SDK command) the IOX-OUTPUT can trigger a relay to open or close. The IOX-OUTPUT is also very versatile, being fully supported through the MyGeotab SDK.

With the IOX-OUTPUT, and the power of MyGeotab, fleets can now send simple on/off commands to an add-on device inside the vehicle. This can be used to turn on a buzzer or light inside the vehicle, informing the driver of any driving conditions, or needing to stop at the next truck inspection area.

I found this in a blog post about IOX's: https://www.geotab.com/blog/iox-expansion/

It is hard to say how much power it will draw because there are a few conditions that will affect the exact amount. From the GO9 Product guide :

Voltage

12 V and 24 V systems supported

Current

120 mA at 12 V Operating mode (typical/nominal current draw)

250 mA at 12 V Operating mode (max. current draw)

24mA at 12 V (continuous connect draw)

4.5 mA at 12 V Sleep mode (min. current draw)

3.0 mA at 24 V Sleep mode (min. current draw)

✱ NOTE: Maximum current draw values are reached during transmission in regions with fair to excellent cellular coverage. Maximum current draw at 24 V will be less than at 12 V.

GO9 devices can pass through a maximum total current of 2750 mA @ 12 V/24 V to IOX hardware in a daisy chain via resettable overcurrent protection.

With that said you will need to consider what IOX's are connected to the GO device and the location of the vehicle if it is in an area of good connectivity etc.

If you are concerned with the power draw I would test this out and see the results you get then make your decision if this is going to be a good option for you. I am sure there are others in the community they may be able to share what kind of results they have gotten using these setting. Maybe @TonyFC-1053 has experience with it he can share.

Let us know if you have any other questions. We are always happy to help.

Have a great day!

We used to use the "turn GPS receiver off" setting a lot back in the day and from memory it used to just prevent the device from going to sleep. Assuming that it still works in a similar way, I'd expect the current draw to be around the nominal current draw, probably on the lower side since the vehicle won't actually be doing anything.

The "turn external device off" stops all the IOXes from going to sleep so you'd need to add up the current draw for all the IOXes attached. It's pretty tricky to estimate though as some IOXes, like IOX-BUZZ for example, should use less power while the vehicle isn't in use, but some others might use more, depending on how they're set up.

Broadly speaking, even at the maximum settings they shouldn't flatten a battery on their own but they should be used carefully, especially if the vehicle has other devices that draw on the battery.
