Raw SMS messaging
In addition to iDigi-formatted messages, a user can send an SMS message without iDigi modifying
it any way. This method is referred to as “raw SMS messaging”. This type of messaging is useful in
cases when customers wish to use every byte of the SMS message (the iDigi protocol takes
approximately 5 bytes per message of overhead), or when using a device that doesn't have iDigi
protocol support but does have SMS support.
Raw messages are not modified by iDigi and are subject to the restrictions of the SMS messaging
interface. SMS raw messages are subject to the limitations of standard SMS messages: They can be
a maximum of 160 characters. The supported characters are dependent on your carrier, but are
character only (not binary). They are not guaranteed to be delivered, may be delivered more than
once, and are not guaranteed to be correct (they are subject to corruption).
To learn more about this feature, see the iDigi Web Services Programming Guide.
Note: using SMS can involve additional costs
SMS is a feature that may be available as part of your mobile service agreement. However, sending
and receiving short messages (or “text messages”) may have additional costs. Before using the
SMS capabilities of your Digi device, verify with your mobile service provider that your agreement
includes SMS as part of your service plan. Understand the costs of SMS before you enable the
SMS features on this Digi device.
NTP time server settings
The ConnectPort X2e ZB uses Network Time Protocol (NTP) for time synchronization. Using NTP
requires an external NTP time server. Time synchronization is critical to the security of the device,
including validating the certificates that sign firmware update images, as well as to verify the
server certificate if/when connecting to iDigi. Steps are taken to preserve a sense of the time across
reboots, but the availability of an NTP server or servers is important to the long-term health of the
device.
The NTP servers are configured in the web interface on the Configuration > Time page. In
environments where the device cannot directly connect to the Internet, configuration changes to
point to a local NTP server are important. Many users will not need to change the time server
setting. If already connected to iDigi, it is also possible to adjust the time server configuration.
The default values for the NTP time server settings are as follows:
 NTP server 1: my.idigi.com
 NTP server 2: 0.idigi.pool.ntp.org
 NTP server 3: 1.idigi.pool.ntp.org
 NTP server 4: 2.idigi.pool.ntp.org
 TimeZone: Coordinated Universal Time (UTC)
