Section 1. SM4M / SM16M Storage Module Overview
Campbell Scientific’s SM4M and SM16M Storage Modules expand on-site data storage
for users of Campbell Scientific dataloggers. They also provide the user with a convenient
method of transporting data from the field back to the office. The SM4M and SM16M are
compatible with the CR500/510, CR10/10X, 21X, CR23X and CR7 dataloggers as well as
the DSP4 Heads Up Display.
This manual contains two broad divisions. The Overview surveys the Storage Modules
and their function. It also explains how to quickly begin using a Storage Module for
straightforward data storage operations. The remainder of the manual is a technical
reference which describes in detail such operations as: storing data from current
dataloggers, storing data from older dataloggers, data retrieval, and datalogger program
storage and retrieval.
The Overview should be read by all users, as should Section 5 (Data Retrieval). Users
with the CR500/510, CR10/10X, CR23X or with the 21X or CR7 with recent operating
systems (i.e., current dataloggers) should read Section 2, while users of Campbell
Scientific’s older dataloggers should read Section 3. Section 6 (Storing and Retrieving
Datalogger Programs) and Appendix B (Telecommunication Commands) may be used as
needed.
SMS (Storage Module Software) simplifies communication procedures between
dataloggers and Storage Modules. SMS is part of Campbell Scientific’s PC208W
Windows-based datalogger support software. Contact Campbell Scientific for further
information.

1.2 Physical Description
The Storage Module is housed in a sealed canister with a single, 9-pin Dconnector. The Storage Module is connected to a datalogger via the SC12 9conductor ribbon cable.
There are two LEDs (light emitting diodes) adjacent to the connector. A red,
status LED indicates the operational status of the module at power-up (see
section 1.4.7) and a green LED lights when data is being stored in the module.

1.3 Power
1.3.1 Primary Power
1.3.2 Backup Power and Data Retention
Section 1. SM4M/SM16M Storage Module Overview
The SM4M and SM16M are identical except for the amount of memory they
contain. The internal memory is split into 64 kb blocks. There are 64 blocks
of memory in an SM4M and 256 blocks in an SM16M. This equates to a
capacity of more than 2 millio n low-resolution storage valu es f or the SM4M
and more than 8 million low-resolution values for th e SM16M (see Section
4.4).
The Storage Module is powered by 5 VDC received from the datalogger or
from data retrieval interfaces such as the SC532(A) 9-pin Peripheral to RS232.
Pin 1 of the 9-pin D-connector supplies the 5 VDC. Pin 2 is both the power
ground and signal ground.
The modules use non-volatile flash EEPROM memory which does not require
power to retain data. There is no internal b a tter y .
1.4 Function
1.4.1 Operation with Current Datal ogger s
The flash memory will retain stored d ata f or approximately 10 years.
Typically, the flash memory can be erased and rewritten a minimum of
100,000 times.
The SM4M and SM16M Storage Modules supplement the storage capacity in a
datalogger. The Storage Modules can store data from Campbell Scientific
dataloggers and from other devices which properly enable them.
All Storage Module operations occur in one of three basic operational modes:
1. Interactive communication with the datalogger for data and program
storage and retrieval.
2. The Printer-Enable Method for data storage with the 21X and CR7, with
older operating systems, and also with the DSP4.
3. The Telecommunications Command State for data retrieval and other
miscellaneous operations.
The Storage Module uses an interactive command structure with handshaking
when connected to the CR500/510, the CR10/10X, CR23X, or to the 21X or
CR7 fitted with recent software (see Figure 1-2). If the Storage Module is not
connected the datalogger does not send data. The datalogger detects when the
Storage Module is connected and sends the backlogged data the next time it
executes Instruction 96.

The Storage Module can store data either under program control (Instruction
96) or under user control (*8 Mode with CR500/510/10/10X/23X, *9 Mode
with 21X and CR7). Datalogger programs can be stored in and retrieved from
the Storage Module using the *D Mode. The CR500/510/10/10X/23X *9
Mode enables the user to directly execute commands such as: change address,
view data, etc. (see your datalogger manual for full details).

Systems (Printer-Enable Method)
In the Printer-Enable Method (see Figure 1-3), the Storage Module stores all
data received (on pin 9) while the printer enable line (pin 6) is high. The
Storage Module automatically detects the baud rate from the sending device
(9600 or 76800 only). The datalogger cannot detect whether the Storage
Module is connected. Data is sent whether or not the Storage Module is
connected.

Data can be stored in the Storage Module under program control (Instruction
96 or *4 Mode) or under user control (*9 Mode). Operations with the DSP4
Heads Up Displays also use the Printer-Enable Method (see Section 3).

1.4.3 Data Retrieval / Telecommunication Command State
Data retrieval and other interactive operations with a computer take place in
the Telecommunications command state (see Figure 1-4). PC208W uses the
Telecommunications Commands for data r e tr iev a l. Dir ect teleco mmunication
commands can also be sent from SMS (part of PC208W) in the Terminal

Emulator mode. A list of direct telecommunication commands is shown in
Appendix B.

Terminal
FIGURE 1-4. Telecommunications Command State
1.4.4 Memory Configuration
The Storage Module’s memory can be configured as either Fill and Stop or
Ring memory. In the Fill and Stop configuration, the Storage Module stops
accepting data when its memory is full. No data write-over occurs with this
configuration. In the Ring Memory configuration (the default setting), new
data continues to be stored even after th e memory is full. Once full, new data
is written over the oldest data. The Storage Module’s memory configuration
can be changed using SMS or with command 4 of the CR500/510, CR10/10X,
CR23X *9 Mode.
1.4.5 Baud Rates
The Storage Module automatically detects the baud rate of data sent to it.
SM4M/
16M
1.4.6 File Marks
CAUTION
When using the telecommunications commands, sending several carriage
returns will cause the Storage Module to match the computer’s baud rate (see
specifications above).
File Marks are used to separate data in the Storage Module. A File Mark is
automatically placed in the Storage Module’s memory when the Storage
Module is connected to a power source (datalogger or retrieval interface), or
when the datalogger compiles a program containing Instruction 96. For
example, if the user has retrieved data from one datalogger, disconnects the
Storage Module and then connects it to a second datalogger, a File Mark is
placed in the data when the second datalogger is connected. This mark follows
the data from the first datalogger and precedes the data from the second. A
File Mark can also be inserted under program control.
The Storage Module must be disconnected from power for
10 seconds or more to be certain it places a File Mark in
the Storage Module when reconnected.
A File Mark can be placed in the data by using SMS or the
CR500/510/10/10X/23X *9 Mode command 3. The Storage Module will not
1-5
Section 1. SM4M/SM16M Storage Module Overview
store contiguous File Marks; if a File Mark is the last thing stored in memory, a
second file mark will not be stored.
1.4.7 Power-up Status Indication
When power is applied to the Storage Module by plugging it into a datalogger
or SC532(A), the red “Status” LED will flash to indicate the status of the
module.
CAUTION
The Storage Module must be disconnected from power for
a minimum of 10 seconds to ensure it powers down and
performs the status check when reconnected.
After connection there will be a short d elay when neither LED is illuminated.
The length of the delay is variable and is partly determined by the address of
the module. This delay avoids excessive power consumption during power-up,
when several modules are connected to the datalogger. For a module at
address 1 the initial delay will be up to 2 seconds. The delay increases by
approximately one second for each increase in the address number.
The first flash after the delay will last from 1 to 2 seconds, depending on the
last use of the module. Further flashes follow with a 0.5 second OFF and 0.5
second ON spacing.
The total number of flashes indicates the status of the module, as follows:
Module OK 1 flash
Module operating system corrupted 2 flashes
OK and Program area full 3 flashes
Flash memory corrupted 4 flashes
1-6
OK and data has rung around at least once 5 flashes
Storage Module full 7 flashes
Previous operating system load failed 10 flashes
If the module is connected to a datalogger which has data to send, the green
“Write” LED may start to flash shortly after the end of the Status flash, as the
module becomes available to receive data and store it.
The module will only receive data if the status is OK, OK and program area
full, or OK and data has rung around at least once. For any of the other status
conditions the module will not accept any further data until the fault has been
corrected.
Section 1. SM4M/SM16M Storage Module Overview
1.5 Quick Start-Up Procedure
This Section describes the basics of storing and retrieving datalogger data.
These operations are discussed in detail in Sections 3, 4 and 5 of this manual.
1.5.1 Preparation
Before putting the Storage Module into service, connect it to a computer and
use SMS to reset the Storage Module and test the memory.
If it is not possible to use a PC and SMS, you must establish communication
between the Storage Module and the available computer or terminal (see
Section 5), and reset the Storage Module using telecommunications commands
(see Appendix B) or use the *9 Mode in the CR500/510, CR10/10X or
CR23X.
There are two possible reset mechanisms: a full reset and test (command
1248k), which erases the memory and then carries out a thorough test of the
storage memory; and a quick reset (command 1249k). While the 1248k
command thoroughly checks the module, it can take some time to perform this
test (over 20 minutes for larger modules). A quick reset, resets all the memory
pointers and erases the flash chips. It does a less rigorous test of the flash
memory adequate for most purposes. An SM16M will take around 3 minutes
to perform the quick reset.
1.5.2 Programming the Datalogger to Send Data to the Stor age Module
Instruction 96 is used in the datalogger program to send data to the Storage
Module. The Storage Module is connected to the datalogger with the SC12
cable. Each time Instruction 96 is executed, Final Storage data accumulated
since the last transfer is sent to the Storage Module.
For the CR7 and 21X
data to a Storage Module. The Output Enable code should be set to X1, Printer
Enabled ASCII.
The DSP4 outputs data to a Storage Module when the Storage Module function
(or, for older versions of software, the printer function) is enabled.
Instruction 96, the *4 Mode can be used to send
without
1.5.3 Manual Dump
The *8 Mode for the CR500/510, CR10/CR10X, CR23X or the *9 Mode for
the 21X and CR7 can be used to transfer data to the Storage Module under
keyboard control (see Section 4).
1.5.4 Data Retrieval
The simplest method of retrieving data from the Storage Module is to use SMS
which is part of the PC208W support package. If you have a computer which
cannot run this software, the Storage Module telecommunications commands
can be used to retrieve the data. Data retrieval (including interface devices) is
discussed in Section 5.
