Notes
1
Because of the high data rate hardware handshake is needed to prevent data overflow. GNS 5892 signals the host with its
CTS signal that he is ready to receive data. GNS 5892 examines the receptivity of the host with RTS
.
If hardware handshake
is not supported by the host
the RTS signal must be activated externally.
This can be done by connecting the CTS with the
RTS signal directly.
2
If Jumper2 is set, the USBtoUART interface is reset and the serial port can be accessed directly with the Multi-Pin-Connector.

TXD
I
Serial Data Input for command interface (TTL)
This is the UART receiver of the module. It is used to receive commands from system
3
RXD
O
Serial Data Output for ADS-B data output (TTL)
This is the UART transmitter of the module. It outputs ADS-B frames for application.

RTS
I
Request To Send – H/W flow control (TTL)
LOW -> active / HIGH -> inactive
5
CTS
O
Clear To Send – H/W flow control (TTL)
CTS is always LOW. GNS 5892 is always clear to receive serial data.
