Software Differences; At Commands; At*E2Io; At*E2Rs232 - Sierra Wireless GM47 Application Note

4 Software Differences

4.1 AT Commands

4.1.1 AT*E2IO

Changed designators:
With the exception of the four items listed below the GM47r5/GM48r5 will
operate successfully in any application designed for the GM47/GM48.
Addressing these inputs and outputs with the designations referred to for
GM47 using the AT*E2IO command will return error when used on
GM47r5.
The GM47r5 will accept an extra parameter, 6, allowing pins to switch
functionality as required.
Note: Pin 37 - GM47 '5'and GM47r5 'I1' is now not a triggerable input.
The trigger functionality on this pin is lost in GM47r5. However - the
GM47r5 AT*E2IO command now supports the extra IO, 'IO5', which is
triggerable, and has the same functionality as 'IO1' to 'IO4'.

4.1.2 AT*E2RS232

This is a new command recognised by the GR modules, not the GM.
When 'Full RS232' is selected (Factory default) all IO commands on these
pins will return 'error'.
E.G. AT*E2IO commands on 'I1', 'O1', 'O2' and 'O3' will return error
unless AT*E2RS232 status is modified to allow operation on these pins.
