Rhino II – Unexpected Shutdown Despite UPS Installation

Some users report that the Rhino II terminal powers off when the main power supply is disconnected, even though a UPS (Uninterruptible Power Supply) is installed. This issue is typically caused by incorrect power management settings in the device’s configuration.

1. Verify and Update Configuration Settings

• Check the following parameters in the device’s configuration file (typically found in the system's hardware settings or configuration utility):

INI[Hardware]DelayPowerKey=100; Delay in 10ms until power key will go active.PowerOnMode=0; 0 = Ignition or power key; 1 = Ignition and power key; 2 = Always on; Default is 2 — change to 0 to allow UPS supportIgnStartTimeSec=3; Time in seconds the ignition must be active to startIgnOffDelayTimeSec=3600; Time in seconds after ignition goes inactive before shutdown; Default is 10 — increase to 3600 to allow extended UPS operationShow more lines

2. Apply Changes

• Save the configuration file after making the changes.
• Reboot the Rhino II to apply the new settings.

Outcome
With these settings:

• The device will remain powered on when the main power is disconnected.
• The UPS will maintain operation for up to 3600 seconds (1 hour) before shutdown.
• The device will no longer shut down prematurely when running on UPS.
