This article explains how to use the IR Beam Monitor utility that is in the Elo Windows driver

This option will only be available and visible when a supported IR monitor is connected to the system. The IR Beam Monitor function allows user to monitor the health of the IR touch monitor. User can configure this function to periodically check if the Infrared LEDs and receivers are functioning properly.

In the Touchscreen's properties page, the "IR Beam Monitor" button will be visible for IR touch monitors after the monitors are calibrated.



Users can set options below for monitoring IR beam status:

• Enable or disable beam health monitoring.
• Enable logging: Write beam failure messages to Windows’ Application event log with event error level "Error" under Source “EloConfig."
  • Subsequence failures at the same location will not generate duplicated event into the Application log. An "Information" level event is logged when all beams return to working condition.
•  Beam test interval: Specify beam scan frequency in the range of10 to 120 seconds

When the beam monitoring is enabled, a message box along with a shaded a vertical and/or horizontal bar will pop up to indicate the failed beams or blocked area. Touch will not function within the shaded area on the display until the failed condition is corrected.
