3. Disk Operations
The D5200 contains memory which holds programmer data. This memory includes internal
battery-backed RAM chips which are permanently attached to the D5200 circuit board, and
removable RAM cards.
The internal battery-backed RAM is referred to as disk A.
The removable RAM card is referred to as disk B.
Even though data may be stored on several RAM cards, the RAM card which is currently
plugged into the programmer is always considered disk B.
Disk Status
The size of a disk and the amount of memory currently available on a disk can be viewed using
the DISKSTAT feature. To view this information, scroll to DISKSTAT from the Product
Handlers menu using the red or keys, and press the red ENTER GROUP key.
Current Disk: Disk A is the internal battery-backed RAM. Disk B is the removable RAM
card. The programmer can display data from only
one
disk at a time (the disk indicated
by Current Disk). See
Changing the Current Disk
to set up the programmer to display
data from a different disk.
SizeKilobytes: Each disk can hold a certain amount of data, expressed in units of
bytes,
kilobytes (K),
or
Megabytes (Mb)
. 1024 bytes = 1 K, 1024K = 1 Mb. The total amount of
memory of the Current Disk (A or B) is displayed in SizeKilobytes.
FreeKilobytes: Handlers, records, and help files take up a certain amount of memory
on a disk (see Figure 4). The FreeKilobytes field displays the amount of memory on
the Current Disk (A or B) that is currently available for storing additional handlers, help
files, and records. Figure 4 contains the following information:
Handler Size: The amount of memory consumed by the actual handler.
Help File Size: The amount of memory consumed by the handler help file.
Record Size: The amount of memory consumed by each record.
Space O/S Allots: The amount of memory that is reserved for use (by the Operating
System) when the first record for the handler is saved.
Number of Records: The number of records that can be saved in the memory
reserved by the Space O/S Allots. When the number of records saved exceeds this
amount (i.e. five D4112 records), another block of memory (Space O/S Allots) is
reserved.

If your disk (A or B) is 512K or above, use the 512K and Above Columns in Memory Worksheet.
If your disk is below 512K, use Standard Columns.
