2.4 Communication parameter setting
Parameters and communication mode related to the communication that uses the RS-232C interface are set.
There are seven communication parameters.
Communication parameter set values
Item name Set value Initial value Remarks
1 LINE ONLINE, OFFLINE ONLINE
Sets the mode of the communication with the computer (ONLINE/
OFFLINE).
The online command can be executed only in the ONLINE mode.
2 Baud Rate
9600, 19200,
38400, 57600,
115200
19200
Sets the communication speed.
When the communication speed is set at a high speed, the communication
error occurs easily.
If the error occurs frequently, set the communication speed to a low speed.
3 Length 7, 8 8
Sets the data bit length.
When the data bit length is set at "7 bits", KATAKANA characters cannot
be sent.
4 Stop Bits 1, 2 1
Sets the stop bit length.
If the communication error occurs frequently, set the stop bit length to "2
bits".
5 Parity
0: None, 1: Odd
2: Even
1
Sets the parity check.
Use the parity check as much as possible.
6 Flow
0: None
1: Xon/Xoff
2: RTS/CTS
1
Sets whether or not the data flow control using the XON/XOFF code or
RTS/CTS signal is performed.
When the data flow control is not performed, data missing may occur.
So, set the data flow control as much as possible.
7 Eof 0:CRLF 1:CR 0 Sets the line feed code.

Setting the communication mode and parameters
Step 1
Select [System] - [Communication
Setting] from the initial screen.
Setting the RS-232C communication
mode and parameters
Step 1
Step 2
Set the communication mode.
Press the F2 (ONLINE) or F3 (OFFLINE) key on
the "RS-232C" screen to change the setting
to [ONLINE] or [OFFLINE].
Step 3
Set the communication parameters.
Use the cursor keys to select the set value to
edit, input a numeric value, and then press
the ENTER key.
To set the data, press the ENTER key until the
cursor selects the numeric value in [Baud
Rate].
* When pressing the ESC key halfway, the
edited contents are canceled.
* Pressing the F4 key (INIT) initializes the
communication parameters.
Step 4
Press the ESC key to exit the data
editing.
