Host Command Reference
BR - Baud Rate
Compatibility: All drives
Affects:
Serial communications
See also: TD, PB, PM, PR commands
Sets or requests the bit rate (baud) for serial communications. At power up a drive will send its power-up packet
at 9600 baud. If a response from a host system (such as a software application from Applied Motion) is not
detected after 1 second and the drive is configured for SCL or Q operation (see PM command) the drive will set
the baud rate according to the value stored in the Baud Rate NV parameter. A Host system can set the baud rate
at anytime using this command. See Appendix B, “Host Serial Communications” for details.
NOTE 1: Setting the value takes effect immediately.
NOTE 2: Due to processor speed limitations, -Si drives can accept only parameter values 1, 2 or 3. -S and -Q
drives will accept parameter values of 1-5.
