PRINTER COMMUNICATIONS
Advantage printers may be equipped with Centronics parallel, RS232
serial, and/or Ethernet communication ports, wired as shown below.
Serial input connector (DB9S)
Standard printer cables
The following standard cables available for Advantage printers:
Centronics parallel cable:
Order CSI P/N 61-00-0002
RS-232 cable, DB9 to DB9:
Order CSI P/N 90-88-0079
RS-232 cable, DB9 to DB25:
Order CSI P/N 90-88-0078
Serial port communication parameters
Advantage printers are configured as
DTE
equipment, and use
RTS
/
CTS
handshaking or
XON
/
XOFF
protocol (control characters are
DC
1 and
DC
3).
The serial port supports the following parameters:
Speed:
600, 1200, 2400, 4800, 9600, 19200
Parity:
Odd, Even, or None
Word length:
7 or 8 bits
Stop bits:
1 or 2 bits
Default parameters:
9600 baud, no parity, 8 data bits, 1 stop bit
Note:
Advantage printers require a “null modem” when connected
to another
DTE
device (i.e., a personal computer). Our serial
cables are wired in a null modem configuration. Other cables
may require an external null modem adapter.
