RT MESSAGE RESPONSES, OPTIONS & EXCEPTIONS, Cont.
Circumstances for
Received Message
Valid receive
command followed
by invalid data word
(Manchester, parity
or bit count error).
Valid receive command
followed by one or more
good data words, then
a data word having
Command Sync
Any valid command
followed by wrong
number of data
words (too few or
too many words)
RT-RT where CW1
is a valid non-mode
receive command.
CW2 is a non-mode
transmit command
valid for different RT.
(Normal RT-RT
receive message)
RT-RT where CW1
is a valid non-mode
receive command.
Transmit command
CW2 has an error:
T/ bit = 0, or CW2
subaddress equals
0 or 31 (mode code),
or CW2 has same RT
address as CW1.
RT-RT where CW1
is a valid non-mode
receive command.
CW2 is valid for different
RT but transmitting RT
does not respond in time.
RT-RT receive command
(CW1 is valid). The
transmitting RT response
has one of these errors:
invalid word (Manchester,
(sync, bit count, parity or
word count error). Also
includes transmitting RT
response with Message
Error or Busy status
followed by no data words.
