description

default values in bold

VideoFunction

Defines if the board acts as video transmitter into the D2X network or as video receiver. The TX sends the video stream from HD camera connected to MIPI CSI port to RX point-2-point. The RX outputs recived video data on HDMI port. The communication partners are defined via the MAC destination addres.

TX	Board acts as video transmitter
RX	Board acts as video receiver

VideoInOut

Defines the video source/output setting

0	Std input/output of application
1	File fifo
2	Uses ip adress and video port that is configured under VideoUDP

TelemetryDevice

Defines the telemetry hardware port. Bidirectional serial. Baudrate used on this device is configured via TTYBaud.

/dev/ttymxc3	UART4 - D2X board
/dev/ttyGS0	USB-OTG port
/dev/ttyAMA0	serial port on RaspberryPi

Interface

wave-raw

Channel

CCH

PowerOutput

RF output power in 1/2 dBm.

0	0 mW - minimum value
24	15.8 mW
28	25 mW - maximum allowed EIRP on ISM band
46	200mW - maximum transmitter output power of uBlox Vera module

ChannelNumber

Defines the frequency channel number.

165	ISM band - see Frequency usage for further details
