4.10. GPIO Interface
The GPIO (General Purpose Input/Output) port is a multifunctional input/output interface to control the
transmitter or third-party devices and peripherals. You can establish connection between the controller/
controllabledeviceandthetransmitterbythe8-polePhoenixconnector.Sevenpin'sdirectionisconfigurable
independently based on needs of the application.
