3.0.1 Communications Interfacing
Using a data detection process, the interface selection occurs automatically in
the printer. At power-up, the printer begins monitoring the interface ports for
activity. When the host transmits data, the printer port detecting this data is set
‘active’ and remains active as long as data flow continues. Once the received
data flow stops and the Host Timeout Value (see Section 4.1.5) is exceeded, the
detection process will be repeated; in addition, should the data flow stop before
a complete label format is received, the format will be ignored and must be sent
to the printer again.
;
Note: To change an active port immediately, cycle the printer power ‘On’
and ‘Off’.
Parallel Port:
The parallel port interface has two menu selectable modes of operation: uni-
directional or bi-directional. Uni-directional mode is forward channel
communication and requires a Centronics
®
cable with a 36 pin male connector.
Bi-directional mode is IEEE 1284 Compliant, using forward and reverse
channel communications. In this mode, data can be sent to the host provided it
is also IEEE 1284 Compliant and has supporting software. This mode requires
an IEEE 1284 cable with a Centronics
®
36 pin male connector.
Serial Port:
The serial port interface supports RS-232C and, if equipped, RS-422
communications. The following list of printer serial port settings are menu
selectable and must be set to match the host computer serial port settings; see
Section 4.1.5.
•
Baud Rate (communication speed)
•
Word Length
•
Word Parity
•
Number of Stop Bits
•
Handshaking Protocol
In addition to these settings, the serial interface cable must a have specific pin
configuration (pin-out) for proper data exchange. The different serial cables,
their respective pin configurations, suggested applications and part numbers are
shown on the next page (contact your reseller for ordering information).
