(6) SIGNAL EXCHANGE TIMING
●
When NC receives.
Data can be received in the following sequence and timing.
NC sends code DC1.
(b) At code DC1, the machine under control starts to send data to NC.
(c) If the NC can not process data in time, it sends out
(d) At code DC3, the machine stops sending data within 10 characters.
NC again sends code DC1 after processing data.
(f) At code DC1, the machine sends out the data that follows the previously sent one.
Upon reading in the data, NC sends out code DC3.
(h) The machine stops sending data,

When NC sends out data
NC sends out data in the following sequence and timing.
NC sends out code DC2, and subsequently sends out data.
(b) If the machine under control can not the data in time. NC stops CS at no
10 BUSY signal.
(c) Upon completion
data that succeeds
(d) Upon completion
of the data processing by the machine, NC turns on CS. NC sends out
the previous one.
of data sending, NC sends out code DC4.
