CEI-100/CEI-200/CEI-x20 User’s Manual 80
If the item is ARU_Rn_SDI_FILTER (where “n” is the receiver
number 1-8), the return is:
AR_ON SDI prefilter enabled
AR_OFF SDI prefilter disabled
For CEI-x20 boards, use ARU_RX_CHnn_SDI_FILTER instead.
If SDI pre-filtering is enabled, only data with an SDI value that
matches the filter value (see below) is stored into the on-board buffers.
If the requested item is ARU_Rn_SDI_VALUE (where “n” is the
receiver number 1-8), the active SDI filtering value is returned (in the
range 0-3). For CEI-x20 boards, use ARU_RX_CHnn_SDI_VALUE
instead.
CEI-x20 Parameters
The remaining parameters are supported by the CEI-x20 only. If these
parameters are used with a CEI-100/200 board, they return an error and
perform no operation.
If the requested CEI-x20 item is ARU_RX_CHnn_BIT_RATE, where
nn is the receiver channel (01 - 32), this function returns:
AR_HIGH 100 K baud receiver rate selected
AR_LOW 12.5 K baud receiver rate selected
If the requested CEI-x20 item is ARU_TX_CHnn_BIT_ RATE, where
nn is the transmitter channel (01 - 32), this function returns:
AR_HIGH 100 Kbaud receiver rate selected
AR_LOW 12.5 Kbaud receiver rate selected
If the requested CEI-x20 item is ARU_RX_CHnn_PARITY, where nn
is the receiver channel (01 - 32), this function returns:
AR_ODD odd receiver parity
AR_OFF receiver parity off
If the requested CEI-x20 item is ARU_TX_CHnn_PARITY, where nn
is the transmitter channel (01 - 32), this function returns:
AR_ODD odd transmitter parity
AR_EVEN even transmitter parity
If the requested CEI-x20 item is ARU_RX_CHnn_SDI_FILTER,
where nn is the receiver channel (01 - 32), this function returns:
AR_ON SDI filtering is enabled
AR_OFF SDI filtering is disabled
If the requested CEI-x20 item is ARU_RX_CHnn_SDI_VALUE,
where nn is the receiver channel (01 - 32), this function returns the
value of the SDI filter (0-3).
If the requested CEI-x20 item is ARU_TX_CHnn_SHUT_OFF, where
nn is the transmitter channel (01 - 32), this function returns:
AR_ON Transmitter has been shut off
