Setting up the printer
2-11
Connecting the printer to your computer
Your printer supports one of the following interface options:
Centronics parallel interface only
Centronics parallel interface and RS-232C serial interface
Centronics parallel interface and USB interface
The RS-232 serial interface is a factory-installed option for a Centronics parallel in-
terface model. Installation of the serial option provides a dual interface feature en-
abling the connection of either interface but inhibiting the operation of both
interfaces at the same time.
The parallel interface connector has wire clips. The serial interface connector has
tapped holes. Cables for these interfaces are available from dealers, cable manufac-
turers, and other suppliers.
The LAN adapter is a user installable option. For details, refer to the Manual that
comes with the LAN card.
NOTE:
If a LAN interface card is installed, the Centronics parallel interface is not
available.
For detailed interface specifications, see Appendix D.
Selecting a Parallel Interface Cable
For the parallel interface, use a cable that meets the following specifications:
3
At the printer end, use a shielded male Centronics connector, such as an Amphenol
DDK 57FE-30360 or its equivalent. To prevent RFI (radio frequency interference),
the connector cover must be connected to the cable shield.
3
At the computer end, most computers (including IBM PCs) require a male DB-25P
connector. Some computers, however, require a Centronics connector. To deter-
mine the type of connector your computer uses, refer to your computer user manual.
3
Make sure that the cable length does not exceed 3 meters (10 feet).
Selecting a Serial Interface Cable
For the serial interface, use a cable that meets the following specifications:
3
At the printer end, use a 25-pin male connector, such as a Cannon DB-25P or its
equivalent.
3
To determine the type of connector your computer requires, refer to your computer
user manual or ask your dealer.
3
The cable length can be up to 15 meters (50 feet). This type of length is required in
many networking and shared-printer configurations.
