Setting the DIP Switches / Connections

Setting the DIP Switches
The DIP switches on the rear panel of the printer
determine the on/off state of the internal SCSI bus
terminator and the SCSI device ID number.
When shipped from the factory, the DIP switches are set
up as follows:
Terminator ON/OFF setting
If the printer is located at the physical end of the SCSI
bus, this switch should be set to ON. Otherwise, if
another device is at the end of the bus, this switch should
be set to OFF.
a) Factory setting
SCSI ID Setting
The SCSI ID selected must be different from that of any
other device on the bus. If two SCSI devices have the
same ID, a malfunction will occur.
a) The SCSI ID is set to 1 at the factory.
Connections
The printer connects to either a Windows or Macintosh
computer via the SCSI interface. The printer can also
connect to a Windows computer via the parallel (IEEE
1284) interface.
Notes
• Connect the AC power cord last.
• When you use the printer in the U.S.A. or Canada, use
the AC power cord supplied. When you use the printer
in a country other than the U.S.A. or Canada, use the
proper AC power cord for your local power system.
• Before connecting the AC power cord, make sure to
turn off the power switches on your computer and any
peripheral equipment.
• Be sure to connect one printer to one computer. Do not
connect two computers to one printer.
• Do not connect the computer to both the PARALLEL
DATA connecter and the SCSI connector of the printer
at the same time.
• Grasp the connector at the end of the cable, and firmly
insert it into the socket.
• The total length of SCSI cabling used with a single-
host computer should be less than 6 meters.
• The parallel data cable should be less than 3 meters
long and should conform to the Centronics
specifications for printer cables.
• Avoid sending parallel data to the printer while the
printer is processing SCSI commands, and vice versa.
• Cable connection requirements vary depending on
computers and peripherals. For the details of your
installation, please refer to the manuals for your
computer and peripherals.
