The configuration menu of the NTP clock driver is accessible through the USB interface. The USB interface of the NTP clock driver is working as an emulated serial terminal.

To access this configuration menu, attach the NTP clock driver to the host terminal through a USB cable and open the appropriate serial port using a terminal emulator program such as PuTTY or minicom.

The serial connection parameters for the NTP clock driver are listed below:

  • baud rate: 9600
  • Data bits: 8
  • Parity: No
  • Stop bit: 1

After establishing a serial connection, press the "ENTER" key to open the NTP clock driver menu. The default menu entries are be listed in the terminal as follows:

1. Configure for DHCP network
2. Configure with static IP address
3. Show network configuration
4. Synchronize date/time
5. Set time offset
6. Show current date/time
7. Configure NTP server
8. Configure clock display format
9. Exit
0. Exit and restart

Selection [0..9]:

If the system is in the boot stage, the terminal may display startup logs as similar to the below listing:

In this scenario, the menu system is available only after the system got bootup. During the bootup, BUSY and SYNC indicators got active. After BUSY and SYNC indicators got turned off, hit the "ENTER" key to access the NTP clock driver menu.
