Recommended Time Server (NTP) configuration for ConnectPort X2e for Smart Energy and XBee Gateways

Introduction

Digi uses two different Time Server (NTP) factory default configurations on ConnectPort X2e for Smart Energy and XBee Gateway ZB products:
  1. A configuration for cellular-connected gateways
  2. A configuration for wired Ethernet or WiFi-connected gateways.
The difference is that the Eth/Wifi gateways have 4 x NTP servers configured, whereas the Cellular gateways only have 1 NTP server configured.


Eth/Wifi Gateway NTP server config:
1.    time.digi.com
2.    0.idigi.pool.ntp.org
3.    1.idigi.pool.ntp.org
4.    2.idigi.pool.ntp.org

Cellular Gateway NTP server config:
1.    time.digi.com

The reason we use a different Time configuration for the Cellular gateways is that although the 4 x NTP server configuration would result in more accurate time-keeping, using the same configuration on a Cellular gateway would result in excessive cellular bandwidth being consumed, and therefore higher cellular bills.
