RoboteQ AX2550/2850 user manual Data Logging in Analog Mode

Data Logging in Analog Mode

•Internal Heat Sink temperatures 1 and 2

•Main Battery voltage

•Internal 12V voltage

•Encoder Speed or Position (AX2850)

The entire string is repeated every 213 milliseconds with the latest internal parameter val- ues. This information can be logged using the Roborun Utility (see “Viewing and Logging Data in Analog and R/C Modes” on page 172). It may also be stored in a PDA that can be placed in the mobile robot.

The string and data format is described in “Analog and R/C Modes Data Logging String For- mat” on page 102. The serial port’s output can be safely ignored if it is not required in the application.

To read the output string while operating the controller with an analog command, you must modify the cable to add an RS232 output wire and connector that will be connected to the PC’s communication port. Figure 67 below shows the wiring diagram of the modified cable for connection to a PC or to a PDA, respectively.
