7.3.2 Auto-baud mode
The auto-baud mode allows the modem to automatically detect the transmission speed used by the DTE.
(only from 1200 up to 115200 bps).
The auto-baud mode is controlled by the command
AT+IPR
. This function is explained in detail in the ERCO
& GENER “Commands List”.
Note: By default, the
GenPro 18e
is delivered with the RS232 interface configured to 9600 bps, no parity, 8
data bits, 1 stop bit.
It is recommended to prefer a fixed speed to the auto-baud mode.
7.3.3 Auto-power supply mode through the pin RI
An option (not soldered by default) exists allowing the auto-power supply mode in 3.8V, through the pin RI ,
for an external application (the GenBlue 15e for instance).
