Introduction

When the EnSURE Touch is registered with a SureTrend Cloud account it will sync with the SureTrend Cloud server when instructed to do so.  The EnSURE Touch must have an internet connection to reach SureTrend Cloud.  At no time does SureTrend Cloud try to reach the EnSURE Touch instrument unsolicited.  However, when the EnSURE Touch is instructed to sync with SureTrend Cloud it will use the ports and protocols listed below.

Overview

Software Updates 

The EnSURE Touch will update its application software over the internet.  The EnSURE Touch does not need to be registered with SureTrend Cloud to get software updates.  If the EnSURE Touch is not connected to the internet and can’t reach SureTrend Cloud it will not update the application software.  The application software size is about 5,000 KB.  The software is downloaded over https from suretrend.hygiena.com

Time Service  

The EnSURE Touch has an onboard real-time clock (RTC) to maintain the time on the instrument.  There is also a super capacitor to maintain the RTC for 2 hours if the battery is removed or drained to 0.  This helps maintain the RTC during battery swapping.  Android will use NTP to keep the RTC current by default.  This can be changed to use suretrend.hygiena.com or not update the RTC.

TeamViewer 

The EnSURE Touch comes with TeamViewer remote support client installed.  It is not active unless the user navigates to the Support screen and requests remote support.
