RS-232 Interface Connections
The printer is configured as Data Terminal Equipment (DTE). Figure 42 shows the internal
connections of the printer’s RS-232 connector.
Figure 42 • RS-232 DB9 MLB Connections
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 43
illustrates the connections required for this cable.

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