7.4 Transmission Format
Transmission format settings based on the shared memory
To change the values of the transmission format automatically set when the power
supply is turned on to any other desired values, the contents of the change are set in the
shared memory, and a software reset is carried out (Y1D is turned on). When the system
has confirmed that the software reset completed flag (XE) is on, the software reset (Y1D)
is turned off, and the transmission format is changed.
The transmission format setting area is addresses 1003 (COM.1) and 1004 (COM.2) of
the shared memory.
