1. Introduction:
The KX-PS13 interface is equipped with an RS-232C adapter and Current Loop interface. It is designed for.
asynchronous data transfer with speeds of 75 ~19200 baud. By adjusting the two 8-set DIP switches on the
serial board, the baud rate, parity check, data word length, DTR polarity, buffer size, buffer type, DTR,
XON/XOFF and ETX/ACK protocol, and self test can be set. This optional interface can be set for current
loop (20mA) by relocating jumpers on the board.
2. installation
Before connecting the interface board, ensure the power cord is disconnected to prevent electrical shock.
To install the serial interface board (KX-PS13), refer to (A), (B), (C), (D) or (E) method depending upon your
printer. |
