2-Series Card Cage System Crestron RACK2

On-Board Memory

The CPU2 has 36MB of built-in memory (non-volatile and volatile). A total of

36MB is broken down as follows: 4MB flash (non-volatile), 32MB DRAM

(volatile), and 256KB NVRAM (non-volatile memory). Flash memory contains the

file system inside the 2-series control engine. NVRAM contains information that is

retained after loss of electrical power. Volatile memory is lost after a power failure.

Refer to the lists below for a breakdown of memory usage for program-related

information stored in the unit.

Internal Flash

The 4MB flash memory consists of approximately 1.5MB used for firmware, and

approximately 2.5MB available for SIMPL, SIMPL+, and web pages. The files that

reside in flash conform to a flat directory structure. The following table presents the

structure of the overall file system.

File System Structure

TOP LEVEL SECONDARY LEVEL DESCRIPTION

\ Root of the file system

DISPLAY Legacy/Unused

SYS Contain various system configuration

files

SETUP Directory used to hold setup files

HTML Web pages

SIMPL Control system program files

SPLUS SIMPL+ module files\

USER User defined files

MAILBOX User mailbox file

CFØ The mounting point for the compact flash

files.

\CFØ\DISPLAY Directory used to hold display files

\nvram The mounting point for NVRAM disk files

Although the file system is case insensitive, the case is preserved to maintain file

checksums. The compact flash directory only appears when the compact flash is

inserted into the system. To reference files on the compact flash, prefix the “\CFØ\”

to any fully qualified path from the Windows environment. For example, if the file in

Windows is “\MyDirectory\MySubdirectory\MyFile.ext”, the complete 2-Series path

for a file on the first Compact Flash slot (onboard) is:

“\CFØ\MyDirectory\MySubdirectory\MyFile.ext”

You do not have to create subdirectories for general files; you can put them in the

root of the Compact flash (\CFØ).

The only time subdirectories are required is when putting bootable projects on the

Compact Flash (\CF0\SIMPL, \CF0\SPLUS), but SIMPL Windows takes care of that

for you when you do the File | Copy to CF function. SIMPL Windows makes the

appropriate subdirectories. The same is true when you put web pages on the

Compact Flash. The tools create the appropriate directories.
