today it is more than a month since we posted a request for support.
Nobody from Sierra knows how this modem is working ?
We would like to thank user muamw10 whose guidance got us on the the move again.
I would like to ask a simple question also, who thought to allow the activation of the modem only using the USB interface on a modem which is designed as an embedded engine and i mean where the majority of the applications involve an MCU and a modem connected via a serial not USB.
So in a few words if you want to activate this modem you need a USB interface just to activate it once, and special software tools which you need to get from your FAE.
You need USBDriverInstallerV3860.exe whichis USB drivers for the modem. Which they dont install correctly on windows XP machines and you need to manually search for the inf files of the drivers at the folders where they install.
And in order to activate the modems you need Watcher.msi which is a software nowhere to be found at the Sierra web site which allows you to activate the modems over the air.
Can someone from Sierra please contact us.
Thank you.
To my understanding, ATD*22899 should works in normal case.
What happens after you send 22899 with Verizon network coverage?
If it doesn’t work, apparently something wrong in the configuration and so please contact your distributor to check and open a case with Sierra.
There are dedicated USB driver for SL50xx available but I don’t know why your distributor cannot provide it to you, and for info, SL50xx do support UART interface.
Also, please reminded that this forum is not an official support channel.
the ATD*22899 does not work probably because the modem is a data modem and it is unable to fullfil a voice call.
We are aware of the USB interface now and how it should be used apparently.
It is not a matter of configuration.
We used to use the Q26 Elite until its sudden EOL and we have products which are Verizon certified.
Can you please send me a private email so we do not turn the board in to support channel as you say.
We are aware that the developer forum is not an “official” support channel for Sierra, it is for users like us who seek help from fellow developers.
I really wonder though where we will get official support afterall.
the final verdict for other users not to loose time.
If you want to activate the SL5011 modem you need a USB interface just to activate it once and special software tools which you need to get from your FAE, they are nowhere to be found on the internet.
USB drivers for the modem, we used USBDriverInstallerV3860.exe
You also need a windows utility Watcher.msi this is also a software nowhere to be found so ask it from your FAE.
The modem is designed to be activated via the USB.
To change back and forth serial and USB you can do it entering config mode with command AT!OEM=176 and AT!SERIALPORTMAP=79
will switch the USB to the serial port.
Command AT!SERIALPORTMAP=75 will switch the serial port back to USB.
The ATD*22899 comand is not working via the serial. This command is issued by the watcher utility using the USB.
It might be possible to activate the modem using the ruim interface and a SIM card, the modem has the SIM wired, we did not test it.
Since the deisgn reference is the same with the SL3010T we assume this procedure probably applies for that one also.
It would be best though if it can be confirmed by someone from Sierra.
