Advanced Display is not charging properly and eventually going flat

Advanced Display is not charging properly and eventually going flat

Issue

Advanced Display V2 (Samsung T580s) are not charging properly and eventually running out of power

Product Line

EcoStruxure Building Operation

Environment

Advanced Display Version 2.0

Cause

If a single straight through USB cable is selected and connected to the USB port on the SmartX controller, it will supply both data and power to the AD V2.

The SmartX controller does not have a high enough power rating to sufficiently charge the AD V2 correctly under all conditions and the battery charge level may dwindle and eventually go flat over time.

(The AD V2 Tablet requires between 0.5A - 1.3A depending on its settings while an AS-P/AS-B USB port supplies a maximum of only 0.5A)

Resolution

There are 2 possible USB cables which can be ordered for use with an AD V2. The Y-shaped 'Y-Cable' and a Straight Through cable.  Both can be used, but with different configuration changes to the tablet settings as detailed below:

Straight Through 3m USB cable (Data and Power):

  • AD V2 is connected directly to SmartX USB port for Data
  • SmartX USB also provides minimum 0.5A supply
  • Tablet brightness must be set no higher than 50%
  • Tablet display timeout must not be set to 'Always On'

Y-shaped USB cable (1 x Data and 1 x Power)

  • AD V2 is connected directly to SmartX USB port for Data
  • Separate USB socket is required to ideally provide 1.3A supply
  • Tablet brightness must be set no higher than 50%
  • Tablet display timeout may be set to 'Always On''
