All bytes of the block except for the check byte ([2*N] bytes) are summed
up, and any bits above 8th bit are discarded.
The CNC reads (2 x N + 1)–byte data (where N is the number of axes) for
every unit time that is set in the parameter. To allow the CNC to continue
machining without interruption, the following minimum baud rate is
required for data transfer between the host and remote buffer:
(2×N+) ××1000 baud (T : Unit time)

If G05 is specified in cutter compensation mode, the P/S 178 alarm is
issued.
Feed hold and interlock are effective.
The mirror image function (programmable mirror image and setting
mirror image) cannot be turned on or off in the G05 mode.
In binary input operation mode, when tool movement starts and stops in
cutting feed mode, exponential acceleration/deceleration is performed
(the acceleration/deceleration time constant set in parameter No. 1622 is
used).
In binary input operation mode, only linear interpolation as specified in
the defined data format is executed (equivalent to the incremental
command for linear interpolation).
The single block, feedrate override, and maximum cutting feedrate clamp
functions have no effect. The program restart, block restart, and
high–speed machining functions cannot be used. In addition, miscella–
neous functions cannot be executed in binary operation.
No data can be stored in memory.
