1) NC output DC2.
(2) NC outputs punch data in succession.
(3) When data processing is delayed at the external device.
(a) Data output stops within two characters including a currently
transmitting character when CS signal is turned off.
When CS signal is turned on again, data transmission starts. (See Fig. A)
(b) If control code DC3 is input to NC, NC stops data output within ten
characters. When control code DC1 is input to NC, NC starts sending
data again. (See Fig. B)
(4) The NC starts sending the next data if the CS signal is turned on after
the external device completes data processing.
(5) The NC issues DC4 upon completing data output.
