Connection to a Computer

The Apollo is equipped with three serial interfaces, these are RS-232, RS-422,

and RS-485, all of them using the 25 pin interface connector (2) at the back.

In most cases, you can use the RS-232 interface for the connection to the

computer. If your computer is located more than 50 ft (15m) away from the

printer you should use the RS-422 interface.

The RS-485 interface is provided for using the Apollo as part of a networked

system.

In addition to the serial port, the Apollo also provides a parallel (Centronics)

interface which offers a faster transfer of data than the serial interfaces.

Therefore, we recommend you use the parallel interface for those applications

where a large number of loadable fonts or complex graphics have to be printed.

For the Centronics interface use the 36 pin interface connector (1).

Select the required interface settings using the Setup procedure (

see Chapter 9

)

and connect the printer to the computer by a suitable interface cable. You will

find a list of typical cables as well as a description of the pin assignment of the

interface connectors in Appendix B.

CAUTION !

Make sure that all connected computers and their connecting cables are

correctly grounded.
