Connecting the MiniSCSI Plus

WARNING: Turn OFF the computer, printer,

and SCSI devices when connecting or dis-

connecting the MiniSCSI Plus. This protects

against damage to any components.

Connect the MiniSCSI Plus parallel port connector to

a parallel printer port on your computer. You may

use either LPT1, LPT2 or LPT3—the MiniSCSI Plus

drivers automatically detect which port is in use.

If your parallel printer port has a copy-protection

device (commonly known as a dongle) or other non-

printer product connected to it, you should remove

the device from your printer port and connect it to

the printer passthrough connector on the MiniSCSI

Plus. If this arrangement causes any problems, either

the dongle or the MiniSCSI Plus must be relocated to

a different parallel port.

Connecting SCSI Peripherals

1 Connect the first SCSI device to the SCSI connec-

tor on the MiniSCSI Plus.

2 Connect other SCSI devices (up to seven total) by

daisy-chaining them to the first SCSI device.

SCSI devices are daisy-chained by connecting

cables in a single, continuous series called the

SCSI bus. SCSI bus cables must run directly from

one device to the next, with no branches. The

SCSI connector on the MiniSCSI Plus is a 50-pin

Centronics-type external connector.

Caution: The MiniSCSI Plus supports only

single-ended SCSI devices. Do not connect

differential SCSI devices to it. Read the

device’s documentation to determine

whether it is single-ended or differential.
