Numbering
All numbers in this manual are assumed to be decimal, unless specifically indicated as
hexadecimal. Hexadecimal numbers in this manual are indicated one of two ways:
•
A number followed by an h is a hexadecimal number, 11h and Bh are hex numbers.
•
A number preceded by 0x is a hexadecimal number, 0x11 and 0xB are hex numbers.

Connecting to the Library

Connect a serial cable between the library and the host system. The library end of
the cable is a DB-9F connector and the terminal end of the cable is an RJ11
connector. The pinout for this type of serial connection is detailed in the
following table.
Configure the terminal emulation protocol.
•
TTY terminal emulation
•
9600 bps
•
8 data bits
•
1 stop bit
•
no parity
All transfers use the standard 128 character ASCII character set.

SSCL Interface Commands

The SSCL interface is a communications protocol and command set defining serial (RS-
232) communication between the host system and the tape library. The command set of
the SSCL interface is similar to the extended SCSI-2 media-changer command set.
In normal operation, the library receives SSCL robotic commands from the host system
through the RS-232 serial port. For development purposes, you can interface directly
with the library using the Serial SCSI Command Language and a properly configured
terminal connected to the serial port on the library.
