66 1892 1335 - Orion Radio Modem Operating Instructions - v2.9 / Aug 2009
The unit is now ready for normal data transmission, and if a new baud rate was set, it now
comes into effect.
A Note About Baud Rate
The baud rate which you set on port Serial A and Serial B, using commands ATB0 and ATB3
respectively, applies both to User Data/telemetry commands and also to AT Command Mode.
If you change the rate, it takes effect when you leave command mode (ATO). After this, you
need to change the baud rate at the GUI or other terminal to suit before you can go back into
command mode.
As with all commands, changes are lost when power to the unit is removed and restored,
unless they were saved using AT&W.
If you are unable to communicate with the unit because the baud rate is unknown, refer to the
table below and try the other three or four possibilities.
