3 . BASIC INTERFACE CONFIGURATION
3.1. Baud Rate Set-up
This section provides basic information on setting the data communication rate [baud rate] on the Rm interface between MT2 and TE2.
3.2. Serial Interface
The default transfer rate is set to 115200bps with support to 230400bps. On the RS232 Serial connection.
NOTE: changes to +IPR rate are written to default NV memory in F0 profile independent of the &W command. Use &W command to write +IPR changes to
3.3. USB Interface
Autobaud is intrinsic within the functionality of USB. However the +IPR setting may be useful to limit baud rate for specific applications. USB automatically negotiates the maximum baud rate available.
