Read and Modify Controller Settings
Description
These commands make it possible to examine and change the controller’s parameters
stored in Flash. These commands will appear cryptic and difficult to use for manual param-
eter setting. It is recommended to use the Graphical configuration utility described in
“Using the Roborun Configuration Utility” on page 159. Note that many parameters will
not take effect until the controller is reset or a special command is sent (see “Apply Param-
eter Changes” on page 97). The complete list of parameters accessible using these com-
mands is listed in “RS232 Accessible Parameter Table” on page 99.
