Epson SQ-850 User Manual

Always disconnect the printer cable from

the printer’s built-in parallel or serial interface before

8. Before you use the interface board, be sure to use SelecType

to set the INTERFACE option to Parallel. (For details, see

the SelecType setting section in Chapter 3.) This is necessary

even if the interface is serial, because the board uses the

parallel connections. However, serial conversion is

performed.

If you are using an optional interface, it may be necessary for

you to alter the communications protocol of the printer or the

computer so that they can communicate properly. In most

cases, you should use the information in your optional interface

manual or your computer’s manual to match the computer with

the interface.

If you are using the #8143 optional board with the SQ printer,

make sure that you read through the section below on baud

rate selection. You may also want to refer to the sections on

handshaking timing and error handling for interface

information specific to the SQ printer.

For all other data transfer conventions, such as word structure

or communications protocol, use the information in the manual

supplied with your #8143 optional interface.
