NDOUT0N Output
Negative Manchester data for driver on bus 0.
PDIN1
Input
Positive threshold exceeded on bus 1.
NDIN1
Input
Negative threshold exceeded on bus 1.
TXEN1N Output
Transmit enable for driver on bus 1.
PDOUT1N Output
Positive Manchester data for driver on bus 1.
NDOUT1N Output
Negative Manchester data for driver on bus 1.
SUBSYSTEM INTERFACE LINES
STROBEN Output
STROBE - Information transfer strobe pulse for words being
transferred on the data highway.
BUFENN Output
BUFFER ENABLE - This line goes low to enable the data
highway buffer between the terminal and the subsystem.
R/WN
Output
READ/WRITE - This line indicates the direction of information
transfer between the terminal and the subsystem. When low,
information is being written from the terminal to the
subsystem.
DTRQN
Output
DATA TRANSFER REQUEST - This line goes low to request
permission to transfer a non mode data word to or from the
subsystem.
DTAKN
Input
DATA TRANSFER ACKNOWLEDGE - This line should be
driven low to grant permission to perform the requested data
word transfer.
MDTN
Output
MODE DATA TRANSFER -
RT: This line goes low to indicate that the data word being
transferred is assosiated with a mode command.
BC: When operating as a passive monitor this line goes low
to indicate that a valid data word is on the data highway and
should be written into the received data latch.
GBRN
Output
GOOD BLOCK RECEIVED - When in RT mode this line will
pulse low to inform the subsystem that the received non
mode data words are valid and may be used.
ADENN
Output
ADDRESS ENABLE - When in RT mode this line will go low
as part of the reset routine to enable the terminal address on
to the data highway.
SYNCN
Output
SYNCHRONISE - This line will pulse low if a valid
synchronise mode command without data is received and
passes all validity checks.
STATENN Output
STATUS ENABLE -
RT: When low this line enables the contents of the
subsystem status latch on to the data highway.
BC: When low this line enables the BC report word on to the
data highway.
MDRN
Output
MODE DATA RECEIVED - This line will pulse low to
inform the subsystem that the received mode data is
valid and may be used.
RXCMDN Output
RECEIVED COMMAND -
RT: This line goes low to indicate that a valid command word
for this RT is on the highway and should be written into the
command word latch.
BC: When operating as a passive monitor this line goes low
to indicate that a valid command / status word is on the data
highway and should be written into the received status latch.
BUSYREQN / HALTREQN Input
BUSY REQUEST / HALT REQUEST -
RT: This line should be driven low as a request for the
terminal to set the busy bit and inhibit non mode data
transfers to or from the subsystem.
BC: This line should be driven low as a request for the
terminal to halt table execution and all subsystem access.
BUSYACKN / HALTEDN Output
BUSY ACKNOWLEDGE / HALTED -
RT: This line will go low to indicate that the subsystem has
free access to the shared store.
BC: This line will go low to indicate that all terminal operation
has been halted and hence the subsystem has free access to
the shared store.
CODENN Output
CODE ENABLE - This line when low indicates that a
word transfer between the terminal and either the
Instruction Store or the Report Store is taking place.
C0
Output
CODE 0 - This line is the least significant address line from
the terminal to the Instruction and Report Stores.
C1
Output
CODE 1 - This line is the least significant but one address
line from the terminal to the Instruction and Report Stores.
