Connection to a Computer
Hermes 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 (15 m) away from the
printer you should use the RS-422 interface.
The RS-485 interface is provided for using the Hermes as part of a networked
system.
In addition to the serial port, the Hermes 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 and connect
the printer to the computer by a suitable interface cable.
CAUTION !
Make sure that all connected computers and their connecting cables are
correctly grounded.
