Figure 7. Two SCSI Termination Examples for the Internal LTO-1 and LTO-2 Drives

Connecting a Serial Cable for Tape Libraries

The Internal LTO-1 and LTO-2 drives include an RS-422 serial interface for tape libraries. This con-
nector is located on the lower left side of the back of the drive (see Figure 6 on page 20).
Table 2 on page 21 shows the pin descriptions for the serial interface connector. The pins on the
LTO-1 drive connector are set on 2-millimeter centers. The LTO-2 library interface uses an in-line
shrouded and keyed 9-pin connector. Pin descriptions are detailed in Table 3 on page 22.
