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.
