RS-422/RS-485 Interconnections
The printer may be connected to a host by either an RS-422 or an RS-485
interface. The DB-25 connector on the rear of the printer uses specific pins
for this purpose. Figure 42 illustrates the required cable wiring for
interconnecting to the printer’s DB-25 connector. Figure 43 illustrates the
internal connections of the printer’s RS-422 or RS-485 connector.
