Pulldown
"Transceiverless Mode"
N/A These two signals MUST be separated for
"Transceiverless" operation.
Transmitter inhibit inputs for Channel B of external
MIL-STD-1553 transmitters. To enable transmission on
Channel B, this input must be connected to logic "0".
50k
To force a shutdown of Channel B, a value of logic "1"
Pulldown
should be applied to the respective TX_INH input.
Digital transmit inhibit outputs. Connect to
TX_INH_OUT inputs of an external MIL-STD-1553
transceiver. Asserted high to inhibit when not trans-
mitting on the respective bus.
50k Pullup RXDATA_IN_A is an output from the Total-
AceXtreme's internal MIL-STD-1553 Channel A
receiver.
These two signals MUST be separated for
N/A
"Transceiverless" operation.
Digital Manchester bi-phase receive data inputs.
Connect directly to corresponding outputs of a MIL-
STD-1553 or MIL-STD-1773 (fiber optic) transceiver.
50k Pullup RXDATA_IN_L_A is an output from the Total-
AceXtreme's internal MIL-STD-1553 Channel A
receiver.
These two signals MUST be separated for
N/A
"Transceiverless" operation.
Digital Manchester bi-phase receive data inputs.
Connect directly to corresponding outputs of a MIL-
STD-1553 or MIL-STD-1773 (fiber optic) transceiver.
50k Pullup RXDATA_IN_B is an output from the Total-
AceXtreme's internal MIL-STD-1553 Channel B
receiver.
N/A
These two signals MUST be separated for
"Transceiverless" operation.
Digital Manchester bi-phase receive data inputs.
Connect directly to corresponding outputs of a MIL-
