TERMINAL CONNECTIONS AND PIN FUNCTIONS
Latched output of the most significant bit (MSB) in the subaddress field of the command
word.
Latched output of the third most significant bit in the subaddress field of the command
word.
Latched output of the least significant bit (LSB) in the subaddress field of the command
word.
Bidirectional parallel data bus bit 1.
Bidirectional parallel data bus bit 3.
Bidirectional parallel data bus bit 5.
Bidirectional parallel data bus bit 7.
Bidirectional parallel data bus bit 9.
Bidirectional parallel data bus bit 11.
Bidirectional parallel data bus bit 13.
Bidirectional parallel data bus bit 15 (MSB).
Broadcast enable - When HIGH, this input allows recognition of an RT address of all
ones in the command word as a broadcast message. When LOW, it prevents response to
RT address 31.
Input of the MSB of the assigned terminal address.
Input of the 3rd MSB of the assigned terminal address.
Input of the 3rd MSB of the assigned terminal address.
Output signal used to inform subsystem of an address parity error. If LOW, indicates
parity error and the RT will not respond to any command address to a single terminal. It
will still receive broadcast commands if BRO ENA is HIGH.
LOW output to the primary side of the coupling transformer that connects to the B
channel of the 1553 bus.
+12 / +15 Volt input power supply connection for the B channel transceiver.
Power supply return connection for the B channel transceiver.
Input from the HIGH side of the primary side of the coupling transformer that connects to
the B channel of the 1553 bus.
Multiplexed address line output. When INCMD is LOW, or A5 through A9 are all zeroes
or all ones (mode command), it represents the latched output of the 2nd MSB in the word
count field of the command word. When INCMD is HIGH and A5 through A9 are not all
zeroes or all ones, it represents the 2nd MSB of the current word counter. (See note 1).
Multiplexed address line output. When INCMD is LOW, or A5 through A9 are all zeroes
or all ones (mode command), it represents the latched output of the 2nd LSB in the word
count field of the command word. When INCMD is HIGH and A5 through A9 are not all
zeroes or all ones, it represents the 2nd LSB of the current word counter. (See note 1).
Data transfer grant - Active LOW input signal from the subsystem that informs the RT,
when DTREQ is asserted, to start the transfer. Once the transfer is started, DTGRT can
be removed.
In command - HIGH level output signal used to inform the subsystem that the RT is
presently servicing a command. When low, A0-A4 (see note 1) represent the word count
of the present command. When high, A0-A4 represent the current word counter of
non-mode commands.
