The factory default baud rate for all servos is 115200. Since smart servos are intended to be daisy chained, in order to respond to the same serial bus, all servos in a project should ideally be set to the same baud rate. Setting different baud rates will have the servos respond differently and may create issues. Available baud rates are: 9600 bps, 19200 bps, 38400 bps, 57600 bps, 115.2 kbps, 230.4 kbps, 250.0 kbps, 460.8 kbps, 500.0 kbps. Servos are shipped with a baud rate set to 115200. The baud rates are currently restricted to those above. 567 567 568 - In thesecond image, the origin,and the corresponding angular range (explainedbelow) have been shiftedby +240.0 degrees:<div class="wikimodel-emptyline"></div>458 +Query Baud Rate (**QB**) 569 569 570 - [[image:LSS-servo-origin.jpg]]<divclass="wikimodel-emptyline"></div>460 +Ex: #5QB<cr> might return *5QB115200<cr> 571 571 572 - OriginOffsetQuery(**QO**)<div class="wikimodel-emptyline"></div>462 +Since the command to query the baud rate must be done at the servo's existing baud rate, it can simply be used to confirm the CB configuration command was correctly received before the servo is power cycled and the new baud rate takes effect. 573 573 574 - Example: #5QO<cr> might return*5QO-13<divclass="wikimodel-emptyline"></div>464 +Configure Baud Rate (**CB**) 575 575 576 - This allowsyouto querytheangle(in tenthsofdegrees)oftheorigininrelation to thefactory zero position.
