Memory

Dolphin terminals have two types of memory: volatile and non-volatile. Each type of memory has its own options.

Volatile

Data stored in volatile memory does not persist through cold boots; see Hard Reset (Cold Boot) on page 3-15.Volatile memory is used for running and storing programs as well as storing program data and is also known as RAM memory. The Dolphin 7850 terminal can have 64MB or 128MB of volatile memory depending on your configuration.

Non-Volatile

Data stored in non-volatile Flash memory does persist through cold boots. The Dolphin 7850 terminal can have 64MB or 128MB of non-volatile memory depending on your configuration.

IPSM:

(Internal Persistent Storage Manager) is the on-board Flash memory. Because this

 

memory is non-volatile, data and programs stored in IPSM are not affected when power is

 

removed or a cold boot launched. For this reason, default programs and files for Dolphin

 

terminals such as Autoinstall are stored in IPSM.

Storage Card:

The other type of non-volatile memory is a factory-installed Secure Digital (SD) memory

 

card. You can add up to 4GB of additional memory on non-RF units only. This card is not

 

user-accessible.

 

If you need to reformat the card, there is an EZFormat Power Tool on 7850s with a storage

 

card installed. For more details about EZFormat, refer to the Dolphin Power Tools User’s

 

Guide, which is available for download from www.honeywell.com/aidc.

Use the Memory system setting to check memory usage after you receive warning messages about memory. There are three tabs: Main, Storage Card, and Running Programs.

Main Tab

This tab displays current capacity and usage of the 64MB or 128MB of on-board, volatile memory.
