While in R/C Mode, the AX500 will continuously send a string of characters on the RS232 output line. This string will contain 12 two-digit hexadecimal numbers representing the fol- lowing operating parameters.

•Captured R/C Command 1 and 2

•Power Applied to Controller’s output stage

•Values applied to Analog inputs 1 and 2

•Amps on channel 1 and 2

•Internal Heat Sink temperatures 1 and 2

•Main Battery voltage

•Internal 12V voltage

The entire string is repeated every 200 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 144). 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 126. 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 the R/C radio, you must mod- ify the R/C cable to add an RS232 output wire and connector that will be connected to the PC’s communication port. Figure 61 and below shows the wiring diagram of the modified R/C cable for connection to a PC.
