Note • Use a a null modem (crossover) cable to connect the printer to a computer or any other DTE devices.

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 45 illustrates the connections required for this cable.
