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.
Make sure that all connected computers and their connecting cables are
correctly grounded.
