Sync1 Specifies the ARINC-573/717 receiver Sync word
#1. This value is ignored for transmitters and non-
573/717 channels.
Sync2 Specifies the ARINC-573/717 receiver Sync word
#2. This value is ignored for transmitters and non-
573/717 channels.
Sync3 Specifies the ARINC-573/717 receiver Sync word
#3. This value is ignored for transmitters and non-
573/717 channels.
Sync4 Specifies the ARINC-573/717 receiver Sync word
#4. This value is ignored for transmitters and non-
573/717 channels.
NumSubFrames Returns the number of sub frames allocated by the
API for ARINC-573/717 channels only.
OperateMode Specifies the operational mode to enable, specify:
ARU_BUFFERED or ARU_MERGED or
ARU_FRAME (ARINC-573/717 channel only)
FRAME mode is not supported on 573/717 channels
running at baud rates above 12288. All baud rates
are supported by 573/717 channels running in
BUFFERED mode.
TimeTagMode Specified the receiver channel time tag mode:
ARU_ENABLE_TIMETAG Enable receiver
time tagging
ARU_DISABLE_TIMETAG Disable receiver
time tagging
Ignored if OperateMode is ARU_FRAME or
ARU_MERGED
Parametrics Parametric enable/DAC voltage settings:
If this call is for ARU_TRANSMITTER and the
board supports parametric transmit voltage, the
value is 0x01-0xFF; API programs the transmit
DAC with the supplied value. If value != 0xFF, the
PARAMETRIC ENABLE bit is set in the channel
control word. If specified as 0x00 the DAC value is
not changed and the channel is programmed to
disable variable output voltage.
