8 - 10 MK22X0 Series MicroKiosk for CE .NET 4.2 Product Reference Guide

Network Time Update: SNTP Client

The MK22X0 Simple Network Time Protocol (SNTP) client can automatically set and update the MK22X0 time and
date through the network. Use this feature to set the system time and date after reboots or power outages. This
feature also ensures consistent time and date stamping across a fleet of MK22X0s. The SNTP Client program
queries the specified SNTP server over the network to set the time and date.
The SNTP client shipped with MK22X0 WinCE 4.20 is the Microsoft default SNTP Client program. (This is a
change from the WinCE 4.1 operating system, which had a custom SNTP client).
MK22X0 allows changing four parameters of the SNTP Client. See

Memory Management

Flash: Nonvolatile (Persistent) Memory

•
The MK22X0 64 MB configuration has 64 MB of available nonvolatile flash memory. 5 MB is committed for
platform partition use to install external driver packs such as RF drivers, and 27 MB is available for
developer's applications within the application partition (folder). The data partition (folder) has no available
memory. The data stored in flash memory persists through cold boot cycles.
•
The MK22X0 128 MB configuration has 128 MB of available nonvolatile flash memory. 5 MB is committed for
platform partition use to install external driver packs such as RF drivers, and 59 MB is available for
developer's applications within the application partition (folder). The data partition (folder) has no available
memory. The data stored in flash memory persists through cold boot cycles.
To increase usable persistent (flash) memory, use the Terminal Configuration Manager (TCM) to adjust the
allocation of memory between the application and data partitions. See
Manager.
Add a PC card to the MK22X0 to increase the non-volatile memory available for file storage.

RAM: Volatile (Non-Persistent) Memory

The MK22X0 has 32 MB of DRAM volatile memory. Developers can automate control of the device's RAM (volatile)
memory allocation (storage vs. memory used to run programs) to persist memory allocation settings through cold
boot cycles.
Use the Symbol RDM or the System Menu to permanently configure RAM memory allocations (memory used to
run programs). (
