[Designation] Valid / invalid real-time command

[Valid limits] 3 (pL+pH×256) 65535
m=20
a=1,2
b= 0, 1, 48, 49
[Initial value]
a Real-time command type Initial value
1 DLE DC4 fn m t (fn=1): real-time output of the
designated pulse
Valid (b=1)
2 DLE DC4 fn a b(fn=2): execution of the power-off
processing
Valid (b=1)
[Function] (1) It designates the valid or invalid processing of real-time command as below:
a b Function
1 0, 48 No processing to DLE DC4 fn m t (fn=1) (invalid)
1, 49 Processes the DLE DC4 fn m t (fn=1) (valid)
2 0, 48 No processing to the DLE DC4 fn a b (fn=2) (invalid)
1, 49 Processes the DLE DC4 fn a b (fn=2) (valid)
pL, pH is m and it designates the subsequent byte value as (pL+pHx256).
a designates the real-time command type.
b designates whether it is valid or invalid.
(2) It is recommended that the real-time command be designated as invalid by this ommand
in advance, if the data sequence that matches the codes, which make up the real time
command during bit image data, exists.
