PIN HEADER CONNECTION Figure 2. 4-Level IO Control on EVM The DS125BR111EVM is quickly setup for use in pin control configuration. Jumpers listed below should be installed on the EVM for pin control. 1. J4 – 3.3 V operation: Use the J1 and J3 connectors to supply 3.3 V power to the EVM. The EVM power connections are designed to accommodate 1287-ST quick connect tabs or directly soldered to power leads for connection to a lab power supply.
