6.1.2. Hardware Setup
1. Connect the provided DB9 serial cable between the PC’s serial port and the TC-RTC evaluation board
2. Apply power to the evaluation board using the provided dc power adapter.
6.1.3. Interacting with the TC-RTC
1. After the board is powered on for the first time, the board firmware will perform a temperature sensor/ADC offset
2. HyperTerminal should now be displaying initial date, time and temperature information from the board. You can
3. Type the “s” command to toggle off the auto-display mode that displays the time once every second. Note that
4. Type the following “w” command (write) to program the device with a new time and date. See "Appendix A—TC-
5. Type the “r” command (read) to get the current time and date information from the device.
6. Type the “s” command to toggle on the auto-display mode.

calibration. For valid calibration, a soak period is required before the calibration is done. Wait for 15 seconds for
calibration to complete. At the end of calibration, the green LED on the board will start blinking at a 1 Hz rate.
program the current date and time data into the board. This data should be trans-coded to the format expected
by the device firmware. Refer to "Appendix B—TC-RTC: Implementation Details" on page 12 for the data
format. Note that the AM/PM information is encoded in the same byte as the hour. Here are some examples:
commands should be only in lower case.
