12 410 ECA Operators Manual
CHAPTER 3: COMMUNICATIONS
The 410 ECA 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 ECA's 9-pin RS-232 serial port. Out of the box, unless
otherwise requested, the Microcom 410 ECA 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.
If XON/XOFF hand shaking is used, the only signals the 410 ECA requires are RXD, TXD, and
GND. If hardware (CTS) hand shaking is used, a CTS signal is provided and an RTS signal is
required. 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.

3.2 PRINTER CABLES
Warning: Connection of a serial 410 ECA to a parallel port may result in damage to the printer
and/or computer.
The printer cables needed for the 410 ECA printer are standard and available through Microcom.
A NULL-modem cable is not required because the printer is DCE equipment.
If the host has a...
25 pin serial com port - Use a standard 25 pin male to 9 pin male serial cable.
9 pin serial com port - Use a 9 pin female to 9 pin male video extension cable.
