Memory - Honeywell Dolphin 7850 User Manual

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
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 has 64MB of volatile memory by default.
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 in 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.
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.
