LED Indicators
The LK204-7T-1U
has 6 General Purpose Outputs which control 3 bi-colour LEDs. Red, green, and
orange-yellow colours can be created using these software controlled GPOs. Odd numbered GPOs
control red while even numbers switch the green aspects of the LEDs, as shown in the
table below.
