Interface Boards

WARNING: 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.
