for all rs-232 input and output signals, the printer follows both the electronics industries association’s (eia) rs-232 specifications and the consultative committee for international telegraph and telephone (ccitt) v.24 standard signal level specifications.
table 4 shows the pin configuration and function of the rear panel serial data connector on the printer.
an interface module is required for rs-422/rs-485 interface support (see page 109).
rs-232 interface connections
the printer is configured as data terminal equipment (dte).
figure 43 illustrates the internal connections of the printer’s rs-232 connector.
the cable used to connect the printer to a computer must be a null modem (crossover) cable. if you want to connect the printer to any other dte devices, a null modem cable must also be used.
when the printer is connected via its rs-232 interface to data communication equipment (dce) such as a modem, use a standard rs-232 (straight-through) interface cable. figure 44 illustrates the connections required for this cable.
rs-232 interconnections using a db25 cable
in order to connect the printer’s rs-232 db9 interface to a db25 connector, an interface adapter is required (zebra part # 33138). a generic db25 adapter may also be used, however the +5vdc signal source would not be passed through. figure 45 illustrates the connections required for the db9 to db25 interface.
the cable used to connect the printer to a computer must be a null modem (crossover) cable. if you want to connect the printer to any other dte devices, you must also use a null modem cable.
rs-422/rs-485 interconnections
a jumper on the computer’s main logic board needs to be installed on jp1, pins 2 and 3, in order for the rs-422/rs-485 interface adapter to function properly.
to connect the printer’s rs-232 db9 interface to a host computer through an rs-422 or an rs-485 interface, an interface adapter is required (zebra part # 33130). figure 46 illustrates the required cable wiring for interconnecting to the interface adapter’s db25 female connector.
