Appendix FChoosing and Setting Up Optional Interfaces

This appendix contains information on Epson interfaces compatible with LQ printers, instructions on choosing the right interface for a particular job, and instructions for installing internally mounted interface boards.

Compatible Interfaces

You can use a number of optional interfaces that supplement the LQ’s built-in parallel and serial interfaces and the standard 8K data buffer. These fail into three main categories:

•IEEE-488 and other special interfaces, which allow connection to computers with other interface requirements (the Apple interface is installed in the computer rather than the printer)

•Buffer interfaces, which provide a larger data buffer to release the computer for other tasks when printing large amounts of text

•Serial interfaces providing additional features not available with the standard interface.

The following Epson interfaces are compatible with LQ printers. Note that some of these are no longer available, and that others are not available in all countries.

*8131	Apple II parallel interface
*8143	Serial interface with baud rate selectable between
	75 and 9600
*8145	RS-232Wcurrent loop interface type 2
#8148	Intelligent serial interface
“8149	32K buffer serial interface
%149M 128K buffer serial interface
*8161	IEEE-188 interface
*8165	Intelligent IEEE-488 interface
*8172	32K buffer parallel interface
*8172M	128K buffer parallel interface

If you are using an optional internal interface, select parallel on your SelecType panel and do not connect anything to the parallel interface connector in the rear of the printer.
