2.14 LED and Buzzer for System Diagnosis
In a “headless application” (an application without a monitor display), it is always diffi-
cult to know the system status. Another PC may be needed to monitor a headless
device's status via RS-232 or Ethernet. In order to solve this problem, UNO-3000G
offers a solution which can diagnose system status through PL1/PL2 programmable
LED indicators.
