Using I/O in a PRIZM Cloud Blueprint

The Phoenix Connector I/O is implemented through I2C peripherals, including an I/O expander, so its Prefab pin and channel numbers are separate from the ESP32-S3 native GPIO numbers. To use these I/Os in a PRIZM Cloud Blueprint, select the Prefabs below and configure their pin or channel numbers using the mappings shown. The Phoenix Connector pin # identifies the physical terminal in the table above; the Prefab pin number or Prefab channel number is the value to use in the Prefab.

For all three Prefabs, set I2C channel to 1 and I2C speed to 400 kHz. The analog input channel number below selects the input and is separate from the I2C channel setting.

Digital Output

Use the Digital Output (Digital Expander) Prefab.

RS485 on this connector runs half-duplex, so the UART needs its DE (driver-enable) pin assigned in Hardware settings — on this gateway, GPIO 46 is the only pin that works for DE. Assigning any other GPIO there leaves the RS485 bus unable to start, even though the form accepts the value.
