The status normally open and normally closed refers to inactive signals.
The
READY
signal is active when the printer is in “normal” working conditions i.e. it is
ON-LINE or it is printing. It is inactive when the printer is OFF-LINE or simply switched
off.
The same rules apply for the DTR signal of the serial RS232.
The
SYNC
signal gives the synchronism for the automatic applicators. The signal is sup-
plied by an external controller to indicate that a print session has started. The signal is ac-
tivated when the printer is configured as an applicator (/*A1 or /*A2 e N-xxx0000). The
signal is configured through the /a parameter. In particular, if /a0 =>SYNC is active when
an application cycle starts (printing of label and its application) and becomes inactive at
the end of the cycle when the photocell is again ready to detect the presence of a package.
If /a1 => SYNC is active when a print session starts (one or more labels) and becomes in-
active at the end of the session (there is no transition between one cycle and the next).
If the external photocell is deactivated i.e. package present, the two modes of operation
become similar. Only if the photocell is in function and there is therefore a time interval
between one cycle and the next will the two configurations be effectively different.
In this case, if only one label is printed /W0001, the signal is active when the printer starts
to print and becomes inactive at the end of the print. If instead a batch of labels is printed
/W0050, there is only one transition of the signal and not at the end of each single label.
23.3.2 Input (optoisolated) "D" 9 pin female
The input signals are used to synchronise the printing of the label with external events e.g.
the removal of a label (dispenser mode) or the arrival of a package which has to have a la-
bel applied to it. (applicator photo cell).
The signals can be generated by photocells or simple switches. The following table gives
the connections for either case:
