Analog and R/C Modes Data Logging String Format

Controller is on, Radio is turned Off (or Radio On with RC ch3 Off)

Relay deactivates. RS232 is now connected to shared input.

String of Carriage Returns now received by controller.

Computer looks for OK prompt to detect that the RS232 mode is now active.

Note: Wait 5 seconds for the capacitor to discharge before attempting to switch to RC mode if doing this repeatedly. Controller will not reset otherwise.

Analog and R/C Modes Data Logging String Format

When the controller is configured in R/C or Analog mode, it will automatically and continu- ously send a string of ASCII characters on the RS232 output.

This feature makes it possible to log the controller’s internal parameters while it is used in the actual application. The data may be captured using a PC connected via an RS232 cable

This string is composed of a start character delimiter, followed by 13 two-digit Hexadecimal numbers representing 13 internal parameter values, and ending with a Carriage Return character. The figure below shows the structure of this string.

FIGURE 96. ASCII string sent by the controller while in R/C or Analog mode

The hexadecimal values and format for each parameter is the same as the response to RS232 queries described in page 142.

Characters are sent by the controller at the rate of one every 8ms. A complete string is sent in 224ms.

Data Logging Cables

The wring diagrams shown in the figures below describe an easy-to-assemble cable assembly for use to create insertion points where to connect the PC for debug and data
