Interfaces
Your printer offers by default the possibility of operating either via a
parallel, an Ethernet or via an optional serial interface.
This chapter informs you about the parallel Centronics compatible
interface, the Ethernet interface and the optional serial interface and
describes the communication between your computer and the print-
er.
The parallel, the internal ethernet and the optional serial interface
are linked to form a so-called shared interface. Your printer can be
configured to use only one interface or all alternately. When only one
interface is used, it is monitored by the printer. If the printer is con-
figured to use all interfaces simultaneously it monitors all interfaces
for incoming data. As soon as the printer recognizes a signal it
switches to the respective interface and sends the BUSY signal to
the other interfaces. After finishing the data transmission, the printer
remains switched to this interface for a certain period of time (30
seconds). When this time has elapsed, the controller reenables both
interfaces and the sequence described restarts. If incoming data is
on the other interface and the current print position is not “Top of
Form”, a form feed is carried out.
If shared = parallel or shared = serial is set, all other interfaces
are disabled.
In the chapter Options
(page 175) , the interfaces which can be pur-
chased with your printer are listed.
