Easily Perform ASCII Data Communications
• Perform ASCII communications with a wide range of external
devices.
• The C200H-ASC11/ASC21/ASC31 function as special pro-
cessing units with BASIC programming.
• Large-capacity user memory: 200 Kbytes
• Model available with RS422A/485 port.
• Various forms of data exchanges with CPU Unit: Select the best
method for the read/write trigger and timing.
• High-speed data exchanges possible with shared memory (not
dependant on I/O refresh).
• A wide range of interrupt processes: Interrupts fro CPU to ASCII
Unit, communications interrupt, key interrupts, timer interrupts,
error interrupts, etc.
• Easy control of transmission control signals.
• Calculation instructions for error check codes.
• Many BASIC debugging functions (break points, 1-step execu-
tion, execution stop monitoring, etc.)
• Error log supported with up to 30 error records.

Function
The ASCII Units support BASIC language programming and RS-
232C and RS422A/485 serial communications. BASIC programming
enables ASCII communications with essential any external device. It
can also be used as a special processing unit to aid the CPU Unit
without using external communications.
The C200H-ASC21/ASC21/ASC31 provided shared memory with
the CPU Unit, and both the ASCII Unit and the CPU Unit can access
the shared memory asynchronously, providing for high-speed data
exchanges between the two Units without using interrupts.
