Receive Digits
The received data is divided into a block of specified receive digits before conversion as described below:
Example: Received data of 6 bytes are divided in different receive digits. (Repeat is also designated.)
(1) Receive digits = 2 (2) Receive digits = 3
Conversion Type
The data block of the specified receive digits is then converted according to the designated conversion type as described
below:
Example: Received data has been divided into a 2-digit block.
(1) ASCII to Binary conversion
(2) ASCII to BCD conversion
(3) No conversion
Repeat Cycles
When a data register is designated to repeat, the received data is divided and converted in the same way as specified, and
the converted data is stored to consecutive data registers as many as the repeat cycles.
Example: Received data of 6 bytes is divided into 2-digit blocks, converted in ASCII to Binary, and stored to data registers
starting at D20.
