Hi
I got 2 brand new FXT009 og one old siemens tc35i.
Supplier sent one more after the first because we thought it was a failed modem but…
I dont get an echo in hyperterminal or any state on the LED indicator (both modems).
I took them out of the box, inserted sim card, connected cables (power messured:12v), opened a hyperterminal 115200,8,1,none,flow=hardware
There is no LED indication or any reply on AT commands.
I known that sim-card and com port is ok, because is work with the siemens tc35 modem on same mashine.
Its seems like a bad power supply to me. Because the LED of the FXT009 turns on (in red ; either static or blinking depending of the state) when you plug the power. Do you use a power supply adaptor provided by Sierra Wireless or another one?
Supplier tells me that I may be using the wrong boot sequence and should read the userguide again.
What boot sequence??
I’m using “AirLink_FXT_Series_User_Guide-Rev004.pdf”, but san’t finde anything.
Also they suggest that there may be a series of AT commands I should commit before the modem starts to reply.
What AT series??
chapter 6.4 of the FXT User Guide (you have the latest version) says what I wrote before: if the LED is OFF, it means your device is OFF (or the LED is deactivated, although I doubt you deactivated it).
Hi
Yes, you are right. I can’t imagine why the LED or ECHO would be off from factory.
I tried (blindfolded, because of no echo) to turn LED on with : AT+WHCNF+1,1 (ref guide 10.1) and I’ve tried turning on echo with: ATE1
It is frustrating when my siemens modem reacts perfectly in same inviroment and with same sim-card.
Well; I’m out of time on this project. Both modems will be returned and I’ll try with another brand.
