MAINTENANCE TERMINAL

The maintenance terminal is attached to the rear of the M2488 via the 9-pin DIN connector. It has two
functions, use as a terminal to run diagnostics using keyboard input and as a debug port for use with
special tools that can be accessed by remote attach with a modem.
8-7.1 Maintenance Interface
A 9-pin (DB-9) maintenance interface (DTE device) is provided on the rear panel of the tape drive
which is used for maintenance and diagnostic operation. Nearly all maintenance and all diagnostic
capabilities are accessible through this interface. The maintenance interface connector is shown in
