1/
The conversion logic requires a constant supply voltage to operate. Device should not be connected with
power on. A separate LED supply is required.
2/
+5.0 V dc is maximum intensity. Decreasing the voltage will decrease intensity.
3/
Use of LED supply to regulate brightness is not recommended, as display uniformity cannot be maintained.
Pulse width modulation of the blanking input (BI) is the preferred method of brightness regulation.
