Program Interface Library AR_SET_CONFIGCEI-100/CEI-200/CEI-x20 User’s Manual 134For the CEI-x20, internal wrap mode causes the transmit channel to beinternally connected to the same-numbered receive channel. Transmitdata is received as transmitted. If the item is ARU_Rn_SDI_FILTER (where “n” is the receivernumber), then valid values are:AR_ON SDI prefilter enabledAR_OFF SDI prefilter disabledIf SDI pre-filtering is enabled, only data with an SDI value that matchesthe filter value (see below) is buffered. If the requested item is ARU_Rn_SDI_VALUE (where “n” is thereceiver number), the valid value is an SDI in the range 0-3.CEI-x20 ValuesThe following parameters are supported only by CEI-x20 boards. If theseparameters are used with a CEI-100/200 board, they will return an errorand perform no operation. If the requested CEI-x20 item is ARU_RX_CHnn_BIT_RATE wherenn is the receiver channel (01 - 32), the valid values are:AR_HIGH 100 Kbaud receiver rate selected.AR_LOW 12.5 Kbaud receiver rate selected. If the requested CEI-x20 item is ARU_TX_CHnn_BIT_ RATE wherenn is the transmitter channel (01 - 32), the valid values are:AR_HIGH 100 Kbaud receiver rate selected.AR_LOW 12.5 Kbaud receiver rate selected.The CEI-x20 API defines AR_HIGH as 50 Kbaud when setting the baudrate for a CSDB channel, and AR_LOW as 12.5 Kbaud. The functionar_setchparms() is recommended for setting the parameters for CSDBand ARINC 573/717 channels, rather than this function. If the requested CEI-x20 item is ARU_RX_CHnn_PARITY where nnis the receiver channel (01 - 32), the valid values are:AR_ODD receiver parity ON.AR_OFF receiver parity OFF. If the requested CEI-x20 item is ARU_TX_CHnn_PARITY where nnis the transmitter channel (01 - 32), the valid values are:AR_ODD odd transmitter parity.AR_EVEN even transmitter parity. If the requested CEI-x20 item is ARU_RX_CHnn_SDI_FILTERwhere nn is the receiver channel (01 - 32), the valid values are:AR_ON SDI filtering is enabled.AR_OFF SDI filtering is disabled.Note:Note:Artisan Technology Group - Quality Instrumentation ...
