# Connecting the Vision System to an NTP or SNTP Server

You can connect the vision system to a Network Time Protocol (NTP) or Simple Network Time Protocol (SNTP) server.

To configure the connection:

1. Launch In-Sight Vision Suite if it is not already running.

2. Select the vision system you want to configure, then click the Time Settings button to open the utility dialog.

3. Configure the settings as follows:

   - Current Time: Set the vision system date and time. You can set the current time two ways:

     - Use the up or down arrow to change the day to the next or previous day. The time does not change in this case.

     - Use the arrow on the right side to open the calendar and time drop-down menu.

   - Time Zone: Choose the time zone from the dropdown menu.

   - NTP Service: Configure the NTP or SNTP service.

     - Manual: Specify the NTP server or servers to use. You can add, remove, move, edit, or update servers by entering or modifying the URL or IP addresses of the desired servers. This is the default setting. You can add maximum four servers.

     - Locate Using DHCP: The vision system attempts to connect to an NTP server provided by a DHCP server.

       Note: If the DHCP server does not advertise an NTP server or the NTP servers advertised by DHCP are not accessible, the date and time are set to the default setting (Sat Jan 1 00:00:00 UTC 2000).

     - None: No NTP server is used. The date and time are set to the default setting of the vision system (Sat Jan 1 00:00:00 UTC 2000).

       Note:
       - You can also set the current date and time values manually for the job in the adapter with the $System.DateTime.SetSystemClock function. See the $ Functions: System - DateTime topic in the applicable adapter help for more information.
       - If the vision system is power cycled, the date and time return to the default setting of the vision system (Sat Jan 1 00:00:00 UTC 2000).
4. Click OK to apply the changes.
