    Remote Terminal Flag--Input signal used
    to control the terminal flag bit in the sta-
    tus register. If LOW when the status
    word is updated, the terminal flag bit
    would be set; if HIGH, it would be
    cleared. Normally connected to RTFAIL .
    Multiplexed address line output. When
    INCMD is LOW or A5 thru A9 are all
    zeroes or all ones (Mode Command), it
    represents the latched output of the 3rd
    MSB in the word count field of the com-
    mand word. When INCMD is HIGH and
    A5 thru A9 are not all zeroes or all ones,
    it represents the 3rd MSB of the current
    word counter.
    Input from the LOW side of the primary
    side of the coupling transformer that con-
    nects to the B channel of the 1553 Bus.
    +5 V input power supply connection for
    the B channel transceiver.
    -15V/-12V input power supply connection
    for the B channel transceiver (Note 5).
    HIGH, output to the primary side of the
    coupling transformer that connects to the
    B channel transceiver.
    Input of Address Parity Bit. The combina-
    tion of assigned terminal address and
    ADDRP must be odd parity for the RT to
    work.
    Input of the 2nd LSB of the assigned ter-
    minal address.
    Input of the 2nd MSB of the assigned ter-
    minal address.
    Power supply return for RTU digital logic
    section.
    +5V input power supply connection for
    RTU digital logic section.

    sharing the same data bus as the

    buffers; and to tri-state address buffer
    control lines, if they are used.

    Read/Write-- output signal that controls
    the direction of the internal data bus
    buffers. Normally, the signal is LOW and
    the buffers drive the data bus. When
    data is needed from the subsystem, it
    goes HIGH to turn the buffers around and
    the RT now appears as an input. The
    signal is HIGH only when DTREQ is
    active (LOW).
    Subsystem Busy-- input from the subsys-
    tem used to control the busy bit in the
    status register. If LOW when the status
    word is updated, the busy bit will be set,
    if HIGH it will be cleared. If the busy bit
    is set in the status register, no data will
    be requested from the subsystem in
    response to a transmit command. On
    receive commands, data will be trans-
    ferred to the subsystem.
    Subsystem Flag-- input from the subsys-
    tem used to control the subsystem flag
    bit in the status register. If LOW when
    the status word is updated, the subsys-
    tem flag will be set; if HIGH it will be
    cleared.
    Multiplexed address line output. When
    INCMD is LOW or A5 thru A9 are all
    zeroes or all ones (Mode Command), it
    represents the latched output of the MSB
    in the word count field of the command
    word. When INCMD is HIGH and A5 thru
    A9 are not all zeroes or all ones, it repre-
    sents the MSB of the current word
    counter.
    Good Block Received--LOW level output
    pulse (.5s) used to flag the subsystem
    that a valid, legal, non-mode receive
    command with the correct number of
    data words has been received without a
    message error and successfully trans-
    ferred to the subsystem.
    Multiplexed address line output. When
    INCMD is LOW or A5 thru A9 are all
    zeroes or all ones (Mode Command), it
    represents the latched output of the LSB
    in the word count field of the command
    word. When INCMD is HIGH and A5 thru
    A9 are not all zeroes or all ones, it repre-
    sents the LSB of the current word counter.
