Storage Modules for Mixed-Array Dataloggers & DSP4
Models SM4M and SM16M
The SM4M and SM16M Storage Modules:
• augment on-site data storage
• are addressable—you can direct specific
or conditional data to up to four
connected modules
• transport data or programs between
datalogger and computer
• provide long-term redundant data
and program storage
• safeguard data during transport;
sealed case is nearly “bullet-proof”
• have built-in Status LEDs indicating
when data transfer is occurring
The SM4M and SM16M are only compatible with
mixed-array dataloggers (e.g., CR510, CR10(X), CR23X,
and CR7) and the DSP4 Heads Up Display. They are
NOT compatible with our CR200-series, CR800, CR850,
CR1000, CR3000, CR5000, and CR9000(X) dataloggers.
General Description
The SM4M and SM16M Storage Modules are housed in sealed canisters fitted with a single, 9-pin D-connector. The
storage modules are connected to, and powered by, a datalogger via an SC12 9-pin cable or an SC12R-6 (longer version)
cable. Two light emitting diodes (LEDs) are adjacent to the cable connector. A red LED indicates the operational status
of the module at power-up. A green LED indicates when data is being stored. The storage modules are addressable
allowing specific data to be directed to a specific storage module. Up to four storage modules can be connected to a
datalogger at one time.
The modules use non-volatile flash EEPROM memory which does not require power to retain data. There is no internal
battery to wear out. The flash memory retains data for approximately 10 years and can be erased and rewritten at least
100,000 times. Standard operating temperature range is -25° to +50°C; extended range is -55° to +85°C.
The SM4M and SM16M are identical except for on-board memory capacity. The memory is divided into 64 kbyte blocks
(64 blocks in an SM4M and 256 blocks in an SM16M). This equates to a capacity of more than 2 million low-resolution
storage values for the SM4M and more than 8 million for the SM16M. Up to four storage modules can be connected to
a logger, resulting in a system storage capacity of approximately 32 million data values.
The storage module can be connected to a PC for transfering programs or data, or downloading a new storage module
OS via our Web site. An SC532A interface is required. The SC532A connects to the storage module via an SC12 cable
and to the computer’s serial I/O port through a 9-to-25 pin or 25-to-25 pin cable.
Support Software
Software for storage module support is provided by SMS Version 3.1 and later. SMS is bundled with LoggerNet and
early versions of PC200W Software. PC200W version 2.0 or higher does not contain SMS. However, PC200W customers
can download SMS, at no charge, from Campbell Scientific’s Web site. Once SMS has been downloaded, it can be
accessed using PC200W. LoggerNet also supports remote collection of data via telecommunication when the storage
module is connected to a datalogger. Contact Campbell Scientific for further information.
A CR10X sends historical or real-time data to an
SM4M. Data can be sent automatically to a connected
module or manually initiated with a keyboard display.
