RS-232 Interconnections
The printer is configured as Data Terminal Equipment (DTE).
Figure 38 illustrates the internal connections of the printer’s RS-232
connector.
Figure 39 illustrates the connections required to interconnect the printer
with the standard 9-pin serial port connector on a computer.
NOTE: If using a 9-pin to 25-pin adapter plug attached to the
computer, use a null modem cable between the adapter plug and the
printer.
NOTE: To connect the printer to other DTE devices with DB25
connectors (such as the serial port of a PC), an RS-232 null
modem (crossover) cable should be used.
