Configure XBee Industrial Gateway Time settings
Digi XBee Industrial Gateway 119
Time Server Configuration page
n
Time server synchronization enable : When you select this setting, XBee Industrial Gateway
uses the Network Time Protocol (NTP) to keep system time synchronized to specified time
servers.
n
NTP Time Precision : Controls how often XBee Industrial Gateway updates time information
from its NTP servers. Options are:
l
Standard NTP Time Precision : XBee Industrial Gateway only synchronizes time with the
servers once every 24 hours. This option trades time precision for network utilization and is
most appropriate for cellular or other bandwidth-constrained devices.
l
High NTP Time Precision : XBee Industrial Gateway synchronizes time on a dynamic
schedule determined by the NTP client to maintain time precision compliant to the NTP
standards.
n
NTP Server 1|2|3|4 : These settings configure the various Network Time Protocol (NTP) servers
that XBee Industrial Gateway uses to obtain current date and time.
For XBee Industrial Gateway Ethernet models, you can specify up to four NTP server settings
to be used as upstream servers in synchronizing time.
The default settings for the four NTP server settings are as follows:
l
NTP server 1 : 0.time.digi.com
l
NTP server 2 : 1.time.pool.ntp.org
l
NTP server 3 : 1.idigi.pool.ntp.org
l
NTP server 4 : 2.idigi.pool.ntp.org
Configure the XBee Industrial Gateway cellular models to use the top NTP Server entry ( NTP
Server 1 ) entry, and leave the others blank because XBee Industrial Gateway checks all NTP
servers that are configured for time-drift. Configuring four NTP time servers for an XBee
Industrial Gateway cellular device would result in excessive and unnecessary cellular usage.
Time Zone Configuration page
Timezone : Specify the times zone for the device. The default setting is Coordinated Universal Time
(UTC).

Enable Time Server Synchronization : When you select this setting, XBee Industrial Gateway
uses the Network Time Protocol (NTP) to keep system time synchronized to specified time
servers.
