MAX-207HW2R User’s Guide

The MAX-207HW2R uses a pre-defined list of NTP time servers if you do not 
specify a time server or it cannot synchronize with the time server you specified. 
It can use this list regardless of the time protocol you select.

When the MAX-207HW2R uses the list, it randomly selects one server and tries to 
synchronize with it. If the synchronization fails, then it goes through the rest of 
the list in order until either it is successful or all the pre-defined NTP time servers 
have been tried. 

Time Protocol

Select the time service protocol that your time server 
uses.Check with your ISP or network administrator, or use trial-
and-error to find a protocol that works.

Daytime (RFC 867) - This format is day/month/year/time 
zone.

Time (RFC 868) - This format displays a 4-byte integer giving 
the total number of seconds since 1970/1/1 at 0:0:0.

NTP (RFC 1305) - This format is similar to Time (RFC 868).
