[Note: Enabling serial port detection of attached devices by selecting the checkbox will

significantly increase the time to discover the network clocks. It is highly suggested to disable this

option unless your network is configured with the special serial port hardware devices]

[Hint: If you are having difficulty discovering attached Masterclock serial port devices that you

have added to your network clock system, open the firewall and/or port control on your

routers/switches to the additional ports 6165 and 6166 for bidirectional UDP messages to include

the RS232 and RS485 devices.]

Advanced Settings

The Advanced button allows for the adjustment of additional network communication settings.

Under most typical operating circumstances it is not necessary, nor is it suggested to change the

advanced settings options.

[Hint: If the advanced settings have been altered for your clock and you begin experiencing

difficulty in getting your clock to synchronize to the NTP time server, or the clock begins acting

erratically, such as performing soft restarts; try returning the advanced settings to the default

values shown above.]
