26 Printer-Applicator-System PAM 3000
Interface Connections
1 - Parallel interface port
2 - Serial interface port
3 - Interface port for scanner
4 - PLC interface port
PAM 3000 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).
In most cases, you can use the RS-232 interface for the connection to the computer. If your
computer is located more than 15m away from the printer you should use the RS-422
interface.
The RS-485 interface is provided for using the printer as part of a networked system.
In addition to the serial port, the printer also provides a parallel (Centronics) interface which
offers a faster transfer of data than the serial interfaces. Therefore, we recommend to 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).
Additionally PAM 3000 has a PLC interface with 25 pin connector (4). This interface is needed
for embedding the printer in the process control of a higher system and is especially used to
start the printing and applying of the labels.
PAM 3000 is also equipped with a 9 pin connector (3) to connect a scanner. This way it is
possible to check a printed bar code immediately after printing and before applying. If the
scanner sends the goodread-signal then the label can be applied.
If there is no scanner connected it is necessary to simulate the goodread-signal. This can
be realized by a plug. An example for the circuit diagram of this plug you can find in
appendix C page C-9.
The interfaces are to connect with suitable cables.
CAUTION !
Make sure that all connected computers and their connecting cables are correctly
grounded.
