Application
The I/O board may be used for 3 different applications:
•
2nd RS 232 interface:
The I/O board provides a RS 232 interface, which can be applied additionally to the one on the
CPU board. The 2nd interface can e.g. be used to connect a bar code scanner.
•
RS 422/485 interface:
If there is a long distance between host and printer, RS 485 or RS 422 is sometimes used in-
stead of RS 232 or Centronics. This is often realized in industrial plants, where galvanic isola-
tion is required to avoid ground loops.
•
Signal interface:
If an applicator is applied with the printer, this requires the exchange of control signals between
printer and applicator. Therefore, signals like „printing is finished“ have to be generated by the
printer and the printer itself must wait for a signal like „start print“ from the applicator, before it
starts printing the next label. Galvanic isolation is provided for robustness. The output signals
can also be used to drive signal lamps.
The two serial interface types cannot be used at the same time.
Signal interface and serial interface can be used at the same time. The signals of both interfaces
must then be related to the same supply system (same ground potential).
