Digital I/O Port

The Digital I/O Port allows the VM1 or VM2 controller to generate and detect 16 digital signals at logic levels. Up to 4 of these Digital I/O Ports may be connected to each I2C Bus. With alternative driver chips this can be increased to 8 Ports, a total of 128 digital I/O channels per I2C Bus. The Digital I/O Port plugs directly into the I2C connector on the Application Boards. The kit includes an I2C cable.
