NSTALLATION
In the interest of clarity, let us assume that the incoming SCSI bus will be connected
to the right SCSI connector, and that the terminator or the outgoing SCSI bus will be
connected to the left SCSI connector.
To properly cable the drive:
1) Make sure that your host system has appropriate SCSI interface card or cards
and software drivers installed. Consider 1) whether the interface card is single-
ended or differential, 2) whether it is SCSI-2 or Fast/Wide SCSI, and 3) if it is
SCSI-2, whether it uses a low-density or a high-density 50-pin connector. All
models of the LoaderXpress require a single-ended interface. Models LXL4105
and LXL4110 require a SCSI-2 interface; the LXL7110 requires a Fast/Wide
interface. Some SCSI-2 interface cards use a 50-pin high-density connector.
There are adapter cables available for connecting an interface card with a high-
density 50-pin connector to the low-density connector used on the LXL4105
and LXL4110.
2) Inspect the terminator and assure that it is a single-ended type, to match your
system. SCSI terminators are usually clearly marked single-ended or
differential.
3) If the LoaderXpress is the only SCSI device you want to connect to the
interface card, simply connect the cable from the interface card to the incoming
SCSI connector, attach the terminator to the outgoing SCSI connector, then
skip to step 5.
4) If you have one or more additional SCSI devices to connect to the interface
card, your LoaderXpress must be connected in daisy-chain fashion. That means
that the cable from the interface card must be connected to the incoming SCSI
connector of the first SCSI device, the cable from the outgoing connector of the
first device must be connected to the incoming connector of the second SCSI
device, and so on. You can connect them in any order. The terminator must be
attached to the outgoing SCSI connector of the last device in the chain.
5) Make sure that each cable you use meets the specifications listed earlier in this
chapter.
6) Be sure that the length of the entire SCSI bus falls below the maximum
permissible length given in the section on SCSI cable specifications, including
the internal SCSI wiring of all the SCSI devices. The internal wiring of the
LoaderXpress is 27 inches (69 cm). Refer to the manuals for the other SCSI
devices to determine their internal SCSI bus lengths.

The LoaderXpress is designed with many configuration options, each offering multiple
settings to support a variety of applications and platforms. The setting of each option
is stored in non-volatile memory in the module. For most applications, you will not
