UCM/GSM4 questions

[juwi_uk]

In your upgrade steps for switching from 7.029 (GSM) to 7.030 (GSM4) can you be a bit clearer about when you physically replace the daughtercard in the sequence; is it while you are still on 7.029 or do you do once you have flashed to 7.030. Maybe it doesn\'t matter but good to be clear so you don\'t wreck anything.

You must replace the  SIM900 submodule  before upgrading to GSM4 firmware
If you do not have SIM900, ULT 7.037 (beta) will still have many of the new features except for the help functions

Hi Chiu
What would be my GSM upgrade path
my GSM seems to have a ribbon cable and no EEprom?
Thanks in advance
Mike

You would need to buy a GSM4 submodule to replace the (Siemens) submodule that you have. I dont know if we have a price for that yet but it should not too high

Next you need to put in the U2 EEPROM. Yours does not have an IC socket in the U2 position. If you are handy with a soldering iron you can solder in the 8 pin IC socket and get a U2 eeprom to plug in

I presume all new UCM\'s are getting a U2 socket fitted as standard these days?

Thanks Chiu

I\'ll get that sorted

U2 have been soldered in to all UCMs for many years, at least 3

UCM/GSM4 firmware 7.030 has been released
Please refer to upgrading method from UCM/GSM3 to UCM/GSM4 in the 1st post on this topic

Thanks Chiu
New module arrived and Eeprom installed

It is worth pointing out that you need to make a link where the jumper was that selected U2 as master.
I failed to spot this first time

Also I had only enabled
Allow SMS Conrol,Arm,Disarm
in the entry for SMS Not the entry for voice
This meant that any txt from my phone returned:

Command not permitted

This was cured by enabling the Voice phone
Allow SMS Conrol,Arm,Disarm

Hope this helps
Mike

Do you have 2 types of phone (i.e. Voice and SMS) with the same number programmed?
