Epson 410 manual Communications, Cable Pinout

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.

3.1CABLE 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.
