5.3 Interfaces
A number of interfaces are available in the ZED-F9P high precision receiver (UART, DDC or SPI), but
not all are supported by the default firmware for data communication. See the ZED-F9P Interface
Description [2] for a description of the interface protocols supported.
It is important to isolate all receiver I/O when VCC is not applied. This is also the case if
V_BCKP is used. The receiver I/O should be allowed to float or connected to a high impedance
if VCC is not applied.
It is advised to use the module VCC for any pull up, level translation or buffer circuits to ensure
compatibility with the module I/O levels and required states.
