Program Transfer
Preparation
For the personal computer to communicate with the ASCII Unit, set the com-
puter communication software as follows:
Baud rate: same as ASCII Unit
Data length: 8 bits
Parity: none
No. stop bits: 2
Also: Full duplex, no echo, no XON/XOFF buffer busy control, no auto line
feed.
Set the ASCII Unit DIP switches to the desired configuration.
(Refer to Section 1 for DIP switch settings.)
Transfer
The ASCII Unit BASIC program must be written on a personal computer
which is connected to port 1 of the ASCII Unit through an RS-232C interface.
A program can be transferred to the ASCII Unit from the personal computer
or any other storage device connected to one of the communication ports
with the BASIC LOAD command (refer to Section 4-2-2 Commands). Pro-
grams can also be transferred from the ASCII Unit’s EEPROM to the ASCII
Unit’s RAM using the LOAD command.
Programs can be transferred from the ASCII Unit’s RAM to the EEPROM or
to a personal computer or other storage device connected to one of the com-
munication ports using the BASIC SAVE command (refer to Section 4-2-2
Commands).
The ASCII Unit can be booted on power application by a program stored in
the EEPROM. To do this, set pin 2 of the left-side DIP switch on the back
panel of the ASCII Unit to ON (refer to Section 1-2 Back Panel).
During data transfer, an overflow may occur if the buffering capacity of the
baud rate settings of the computer and the ASCII Unit are not matched. If an
overflow error does occur, set either a slower baud rate or specify XON with
the OPEN command.
Note The EEPROM’s guaranteed lifetime is 5000 write operations.
