Module Design
Fig. 265 – Pro-Storage: Block Diagram
The glue-logic of the Pro-Storage module has an internal buffer, which can
receive 12 sectors with 128 data words à 32-bits. The glue-logic buffers all
data, which is read from or written into the storage medium. Data is exchanged
with the storage medium sector by sector.
The real-time clock works independently of all other components and is bat-
tery-backed. It provides date and time.
Fig. 266 – Pro-Storage: Printed circuit board and front panel
The module has a width of 1 HP and requires one slot.
LED function
On the front panel there are 3 two-colored LEDs.
The lower left LED displays the status of the storage medium:
The top and lower right LEDs are individually programmable. (see
ADbasic
instruction
SETLED
).
The Real-Time Clock
The module is equipped with a real-time clock from Epson RTC-4553AA. With
simple
ADbasic
instructions, date and time are set and read out, so that a spec-
ified time can be assigned to measurements. Time and glue-logic work auton-
omously.
