• Encoder Speed or Position if module is installed
The entire string is repeated every 208 or 224 milliseconds (depending whether the
encoder module is present) with the latest internal parameter values. This information can
be logged using the Roborun Utility (see “Viewing and Logging Data in Analog and R/C
Modes” on page 192).
The string and data format is described in “Analog and R/C Modes Data Logging String For-
mat” on page 166.
Important Warning
Disconnect the Motor Power (thick red wires) from the battery and power the con-
troller by applying 12V on the Power Control input if you do not wish the motors to
be activated while in Self Test mode.
This could be the case if you only wish to use the Self Test sequence to read the software
revision number or to monitor the joystick capture.
