Chapter 1 Overview
1.1 ASCII Module Overview
•The AS311 is a general purpose serial interface module.
•By using the AS311, the controller can communicate with external devices equipped
with an RS232C/RS485 interface.
•The AS311 has two ports of the serial interface. One port (channel1) can be selected
either RS232C or RS485 by switch setting. The other port (channel2) is RS232C
interface. These two ports can be used independently for data receiving and
transmitting.
•The transmission is asynchronous (start-stop system). ASCII is used as the
transmission data code.
•The figure below shows the typical system configuration.

1.2 ASCII Module Operation Overview
When exchanging data with an external device using the ASCII module, the exchanged
data is transmitted through the following path. Ch1 and ch2 can operate independently.
(1) Data transmission
To transmit data, set the data in the controller register and use the MWRITE
instruction to write in the transmitting area of the ASCII module buffer memory.
Then when the transmit start flag is turned ON, the ASCII module transmits the data
to the external device.
(2) Data receiving
The data received from the external device is stored in the received buffer to be
checked and then stored in the receiving area of the buffer memory. Then after the
ASCII module turns ON the receive data read flag, use the MREAD instruction to
read the data into the controller register.
(3) Data format
The ASCII module can transmit/receive data consisting of a series of ASCII codes.
Data up to 896 bytes can be transmitted at once.
The trailing code of this data is set to CR (0Dh) by default. This code can be
changed to a different code.
