5. Attach the power cables to the drive. Check the SCSI cable and termination
connections and ensure that they are attached correctly and seated firmly.
6.9 Loader/Library Controller Interface
The loader connector (for library tape drive interface) is an RS-422 serial port set
to 9600 baud, 8 bits per character, no parity, and 2 stop bits. All data sent to or
from the library tape drive interface consists of bit-wise encoded hex values.
This 8-pin optional loader connector provides signals to be used when the tape
drive is part of a loader/library configuration. The loader connector provides a
“universal port” that can support various serial interface protocols. The electrical
signals from the SDLT drive need to be translated to the appropriate serial
interface protocol by a hardware and software interface system.
The Molex part numbers for this connector are:
• Connector terminals: 50394-8052
• Connector body: 51110-0850
Figure 6-4 shows a representation of the connector; pin assignments for the loader
connector are listed in Table 6-6.
