store contiguous File Marks; if a File Mark is the last thing stored in memory, a
second file mark will not be stored.

1.4.7 Power-up Status Indication

When power is applied to the Storage Module by plugging it into a datalogger
or SC532(A), the red “ Status”  LED will flash to indicate the status of the
module.

The Storage Module must be disconnected from power for
a minimum of 10 seconds to ensure it powers down and
performs the status check when reconnected.

After connection there will be a short delay when neither LED is illuminated.
The length of the delay is variable and is partly determined by the address of
the module.  This delay avoids excessive power consumption during power-up,
when several modules are connected to the datalogger.  For a module at
address 1 the initial delay will be up to 2 seconds.  The delay increases by
approximately one second for each increase in the address number.

The first flash after the delay will last from 1 to 2 seconds, depending on the
last use of the module.  Further flashes follow with a 0.5 second OFF and 0.5
second ON spacing.

The total number of flashes indicates the status of the module, as follows:

Module OK

1 flash

Module operating system corrupted

2 flashes

OK and Program area full

3 flashes

Flash memory corrupted

4 flashes

OK and data has rung around at least once

5 flashes

Storage Module full

7 flashes

Previous operating system load failed

10 flashes

If the module is connected to a datalogger which has data to send, the green
“ Write”  LED may start to flash shortly after the end of the Status flash, as the
module becomes available to receive data and store it.

The module will only receive data if the status is OK, OK and program area
full, or OK and data has rung around at least once.  For any of the other status
conditions the module will not accept any further data until the fault has been
corrected.
