[Description] Changes the condition of the serial interface defined by a.
a Item
1 Baud rate
2 Parity
3 Flow control
4 Bit length
Baud rate (a = 1) is specified by number.
Example: When defining 19200 bps: 5 bytes as 19200 (Hexadecimal =
31H, 39H, 32H, 30H,30H / Decimal= 49, 57, 50, 48, 48)
Parity (a = 2) is specified by d as follows:
d Function
48 Select no parity
49 Select odd parity
50 Select even parity
Flow control (a = 3) is specified by d as follows:
d
48 Select Flow control of DTR/DSR
49 Select Flow control of XON/XOFF

E pL pH fn a d1...dk
45 pL pH 0B a d1...dk
69 pL pH 11 a d1...dk
Function
Bit length ( a = 4) is specified by d as follows:
d Function
55 Select 7 bits length
56 Select 8 bits length
[Notes] It is recommended that the DIP Switch be used to change communication
condition.
-If the communication control between host and printer does not
correspond, the printer cannot process data from the host normally, and the
host cannot receive data from the printer normally.
This function works in user setting mode.
This function works with serial interface printers.
The communication condition set by this function is enabled by executing
Function 2 or restarting the printer. It is necessary to change the
communication condition of the host to be the same as the printer to
communicate with the printer.
To enable the communication condition set by this function, set DSW 1-5 to
ON (Interface condition selection).
-The serial communication setting is also specified by DIP switch.
-4 baud rates are selectable by this command. [ 2400 , 4800 , 9600 ,19200 ]
-Setting of this function can be changed by Memory switch setting mode by
the panel switch operation.
