TRANSACTION STORAGE CALCULATION
If the configuration of variable field sizes and software options you have is not listed in the
transaction storage table, you can determine the approximate number of transactions by
calculating:
1.
The number of bytes in your transaction record.
2. The number of ROM bytes used.
3. The number of RAM bytes used.
4. The available transaction space
5. The total number of transactions that can be stored.
The calculations vary according to the type of system you have (mag, optical, or CFN Network).
Calculations for each system type can be found in the following subsections.
