3.3.3.3
Shared Interface
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 configured 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.
CX
The parallel section is controlled by the main logic, only I/O Drivers (7407, 74244) are
necessary. Please see also section 3.3.3.1 “General Information”.
RS232C / V 24 (optional)
The serial part is controlled by the main logic only I/O Drivers (L 232 50P) are neces-
sary. They convert 5 V Input signals to RS232 Standard voltage (-12/+12 V). Several
jumpers are prepared to customize the interface.
