CEI-100/CEI-200/CEI-x20 User’s Manual 170
The elements of the AR_CHANNEL_PARMS structure are defined as
follows:
BaudRate Defines the baud rate for the specified channel:
For ARINC 573/717 channels, baud rate/sub frame
size:
ARU_717_SPEED_384 defines a sub frame size of
32 words.
ARU_717_SPEED_768 defines a sub frame size of
64 words.
ARU_717_SPEED_1536 defines a sub frame size of
128 words.
ARU_717_SPEED_3072 defines a sub frame size of
256 words.
ARU_717_SPEED_6144 defines a sub frame size of
512 words.
ARU_717_SPEED_12288 defines a sub frame size
of 1024 words.
ARU_717_SPEED_24576 defines a sub frame size
of 2048 words.
ARU_717_SPEED_49152 defines a sub frame size
of 4096 words.
For CSDB channels:
ARU_CSDB_SPEED_4800 selects 4800 baud
ARU_CSDB_SPEED_9600 selects 9600 baud
ARU_CSDB_SPEED_12500 selects 12500 baud
(same as AR_LOW)
ARU_CSDB_SPEED_19200 selects 19200 baud
ARU_CSDB_SPEED_38400 selects 38400 baud
ARU_CSDB_SPEED_50000 selects 50000 baud
(same as AR_HIGH)
ARU_CSDB_SPEED_76800 selects 76800 baud
For all ARINC channels:
AR_HIGH select HIGH speed (100 Kbaud(50KB if
CSDB))
AR_LOW select LOW speed (12.5 Kbaud)
In addition to the standard AR_HIGH and
AR_LOW baud rate flags, the CEI-820/820TX also
allows the user to specify any desired
transmit/receive baud rate between 5K bps and
