Serial Interface RS-232C

The serial interface has one asynchronous V24 RS232C .
Technical Character:
The following parameters can be modified in SET-UP:
S BAUD RATE:
S BITS/CHARACTER: 7 or 8 bits
S STOP BITS:
S PARITY:
S DTR - Ready/Busy
S XON/XOFF
S XON/XOFF + DTR
Communication Cable:
S HOST: 9 PINS (DB-9S)
S PRINTER: 9 PINS (DB-9S)
This protocol uses the following signal lines:
S Receive Data (RXD)
S Transmit Data (TXD)
S Data Terminal Ready (DTR)
S Projective Ground (GND)
S Data Set Ready (DSR)
S Clear To Send (CTS)

S Signal Ground (SG)
B-2
2400, 4800, 9600, 19200 (bit/s)
In receive mode the printer accepts 1, or 2 stop bits. The
printer transmits always two bits.
none, even or odd.
