410 Operators Manual 15
CHAPTER 3: COMMUNICATIONS
The printer may be connected to PC's, mini-computers, main frames, and many other special
purpose machines. The following sections explain the communication interfaces.
3.1 CABLE PINOUT
Table 2 shows the signals of the 410's 9-pin RS-232 serial port. Out of the box, unless
otherwise requested, the printer communicates serially at 9600 baud, 8 data bits, 1 stop bit and
no parity with both hardware and software handshaking. This configuration may be changed
through software commands as explained in the programming section of this manual. Table 3
shows the optional parallel port configuration.
If XON/XOFF hand shaking is used, the only signals the 410 requires are RXD, TXD, and GND. If
hardware (CTS) hand shaking is used, a CTS signal is provided. XON/XOFF may be disabled
through the software dip switch #1 (see chapter 5). The other signals are offered in the event the
host computer requires them.
