Crestron AV2 User Manual

Crestron AV2 & PRO2 2-Series Integrated Dual Bus Control System
NOTE: Only COM-type devices and cards in the SIMPL Windows program that are
active (not commented out) are monitored.
On-Board Memory
The AV2 and PRO2 each have 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 directory used in ISYS panels to hold
display lists
SYS Contains various system configuration files
SETUP NAT configuration Web pages
HTML Web pages
SIMPL Control system program files
SPLUS Simpl+ module files
USER Used for user-defined files
MAILBOX Directory contains the user mailbox file
CFx
The mounting point for the compact flash files,
where x is the number of the compact flash slot
(0 = on board slot, i.e., \CF0 refers to the on-
board slot)
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 “\CFx\” to
any fully qualified path from the Windows environment. For example, if the file in
Windows is “\My Directory\My Subdirectory\My file.ext”, the complete 2-series
path for a file on the first Compact Flash slot (onboard) is:
“CF0\My Directory\My Subdirectory\My file.ext”
Non-volatile
1. SIMPL+ Variables (Default if no options are specified, or using
"nonvolatile" qualifier or #DEFAULT_NONVOLATILE)
2. Signals explicitly written to NVRAM* (by symbols such as Analog
RAM, Analog RAM from database, Serial RAM, Serial RAM from
database, Analog Non-volatile Ramp, Digital RAM, etc.)
*Commonly used for presets (volume/lighting/dial #s).
