The PD-LED can drive up to 2048 single-color LEDs or 682 RGB LEDs. Because the board has 84 individual drive pins, up to 84 of the 2048 individual LEDs (or 28 of the 682 RGB LEDs) can be driven in parallel. The rest can be driven through up to 6 serial control channels.
The PD-LED can be driven directly by a P3-ROC or indirectly (through a high-speed RS-485 master device) by various other microcontroller-type devices. Each PD-LED has an RS-485 serial interface so that it can chain to other driver boards. Therefore, you can use as many boards as your application requires. Further, since the serial interface will continue to work at distances well over 10 feet (100 feet even), you can locate the boards in the backbox, under the playfield, or anywhere else in your machine.
The PD-LED responds to the following commands:
– the PD-LED does not have LEDs on the board itself (except for a few status LEDs). Rather, it provides connectors for driving external LEDs. Because each application has its own needs and constraints, it’s likely each design has different LED configurations. Driving just about any configuration of LEDs is possible with one or more PD-LED boards.
– the PD-LED is not intended to drive standard pinball-bulb-style LEDs. Rather, it provides low current (22mA) drivers for directly driving LED components, including any of the RGB LED products offered by Multimorphic.
