Connecting the MiniSCSI EPP WARNING: Turn OFF the computer, printer, and SCSI devices when connecting or disconnecting the MiniSCSI EPP. This protects against damage to any components. Connect the MiniSCSI EPP parallel port connector to a parallel printer port on your computer. You may use either LPT1, LPT2 or LPT3-the MiniSCSI EPP 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 nonprinter product connected to it, you should remove the device from your printer port and connect it to the printer passthrough connector on the MiniSCSI EPP. If this arrangement causes any problems, either the dongle or the MiniSCSI EPP must be relocated to a different parallel port. Connecting SCSI Peripherals 1 Connect the first SCSI device to the SCSI connector on the MiniSCSI EPP. 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 EPP is a 50-pin Centronics-type external connector. Caution: The MiniSCSI EPP 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. 4
