38,400 bps)
Note Using interrupts will limit the baud rates that can be used.
RS-232C: Point-to-point (1:1)
RS-422A/485: Point-to-multipoint (1:N)
RS-232C: 15 m
RS-422A/485: 500 m
Receive buffer: 512-bytes
Transmit buffer: 512-bytes
RTS/CTS flow (for receive buffer of external device)
Note ASCII also asserts RTS when sending data.
Xon, Xoff flow (for receive buffers of external device and ASCII Unit)
BASIC
Single task
200 Kbytes
Contents: BASIC source program (up to 4 programs can be loaded) intermediate code,
variables.
Note The BASIC program has battery backup. Make sure the battery is installed before
operating.
200 Kbytes
The BASIC program can be stored in the flash ROM from the user memory area. It can
be loaded into the user memory area when the power supply is turned on or the Unit is
restarted.
Special I/O Unit Area: 10 words
100 words (no battery backup) as follows:
10 word: Setup Area (can be transferred from the DM area words allocated in the CPU
Unit to the ASCII Unit when the power supply is turned on or when the Unit is
restarted).
90 wordGeneral-purpose area (IORD/IOWR area).
Note Read/write is possible using IORD/IOWR instructions from the CPU Unit or
PC_EPUT/PC_EGET commands from the ASCII Unit. The position and size of
the IORD area/IOWR area can be adjusted. When the power is turned on or the
Unit is restarted, the data in the DM words allocated in the CPU Unit can be
transferred to the ASCII Unit. (The PC_EPUT and PC_EGET commands are not
supported by the C200H and C200HS.)
