Page 7: Bullet-Point Differences
Differences between GM47 and GM47r5 2.3 Bullet-point Differences Below the main differences in software are listed. • DSR signal has been implemented sharing with a digital output. • One new general purpose I/O pin added (dual function, allowing either digital I/O or analogue ADC). -
Page 8: Detailed Difference Description
AT*E2IO will now return error when trying to manipulate them, unless AT*E2RS232 is used to change which RS232 pins are in use. Previously GM47 allowed both IO operations and RS232 functions to occur concurrently. LZT 123 7733 R1A... -
Page 9: Led / Io6 (Pin 33)
Default operation designation is as RS232 interface with full hardware flow control. This is as GM47 except pin 32 (DSR/03) was a digital output pin only, OUT5. The power up default of OUT5 is commensurate with that of DSR (OUT5; HI for 10mS then LO, DSR/03; HI for 330mS then LO). -
Page 10: Software Differences
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... -
