SECTION 1. SM192/716 STORAGE MODULE OVERVIEW

Campbell Scientific's SM192 and SM716 Storage Modules expand on-site RAM 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 SM192 and SM716 are compatible with the CR10, 21X, CR7,
and CR21 dataloggers as well as the DSP4 Heads Up Display.

This manual contains two broad divisions. This Overview surveys the Storage Modules and their
function. It also explains how to quickly begin using an SM for straight- forward data storage operations.
The remainder of the manual is a technical reference which describes in detail such operations as:
storing CR10 data, storing data from Campbell Scientific's other 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 CR10 or
with the 21X or CR7 with current PROMS should read Section 2, while users of Campbell Scientific's
other dataloggers should read Section 3. Section 6 (Storing and Retrieving Datalogger Programs) and
Appendix D (Telecommunication Commands) may be used as needed.

NOTE: 21X Microloggers released after February 1989, and CR7 dataloggers released after August
1991, contain the OSX and OS7 Series PROMS which support two major SM functions that earlier
versions do not:

1. The *D storage and retrieval of datalogger programs in the SM.

2. The Instruction 96 transfer of binary Final Storage data to the SM with the capability of not
sending data until the SM is connected. In older versions of the 21X and CR7 PROMS, the
Instruction 96 transfer is simply an ASCII printer dump. Data are sent regardless of whether the SM
is or is not connected.

1-1

SECTION 1. SM192/716 STORAGE MODULE OVERVIEW

FIGURE 1.2-1. Storage Module and SC12 Cable

1.2 PHYSICAL DESCRIPTION

The Storage Module is housed in a sealed
stainless steel canister with a single 9-pin D­connector. The Storage Module is connected to
a datalogger via the SC12 9-Pin Peripheral
Cable.

The SM192 and SM716 are identical except for
the amount of memory they contain. The
SM192 has a CPU card with six 32k RAM chips,
providing 192,896 bytes of storage. The SM716
contains the CPU card plus a memory
extension card with 16 additional 32k RAM
chips. Total storage capacity in the SM716 is
716,672 bytes.

1.3 POWER

1.3.1 PRIMARY POWER

The Storage Module is powered by 5 VDC
received from the datalogger or from data
retrieval interfaces such as the SC532, 9-pin

Peripheral to RS232 Interface, the SM232A
Storage Module - RS232 Interface, or the
PC201 Clock-SIO Tape Read Card. Pin 1 of
the 9-pin D-connector supplies the 5 VDC. Pin
2 is both the power ground and signal ground.

1.3.2 BACKUP POWER

Memory backup power is provided by an
internal 3.5 VDC lithium thionyl chloride battery
when the Storage Module is disconnected from
a primary power source. About 6 years of RAM
backup power can be expected from the lithium
battery at room temperature. Higher
temperatures increase the current drain of the
RAM chips and the self-discharge rate of the
battery while lower temperatures decrease the
battery's capacity, i.e., energy. At 50oC, battery
life will be about 2 years; at -25oC, about 4
years can be expected. If possible, keep the
Storage Module at or near room temperature
when not in use.

1-2

SECTION 1. SM192/716 STORAGE MODULE OVERVIEW

Expected
Battery Life SM192 SM716

@ 25C about 10 yrs. about 6 yrs.
@ 50C about 3 yrs. about 2 yrs.
@ -25C about 6 yrs. about 4 yrs.

NOTE: These figures apply when:

1. The SM is not connected to a primary
power supply (such as a datalogger), and

2. The SM is continuously at one of the
above temperatures.

Meeting these conditions is unlikely in
normal operation.

1.4 FUNCTION

The SM192 and SM716 Storage Modules
provide battery-backed, solid-state, RAM data
storage to supplement the storage capacity in a
datalogger. The Storage Modules can store
data from all Campbell Scientific, Inc.
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
datalogger for data and program
storage and retrieval.

2. The Printer Enable Method for data
storage with the 21X and CR7 with
older PROMS, the CR21, the DSP4,
and non-datalogger devices.

3. The Telecommunications Command
State for data retrieval and other
miscellaneous operations.

The SM can store data either under program
control (Instruction 96) or under user control (*8
Mode with CR10, *9 Mode with 21X and CR7).
Datalogger programs can be stored in and
retrieved from the Storage Module using the *D
Mode. The CR10 *9 Mode enables the user to
directly execute commands such as: check
battery, change address, view data, etc.
(Appendix A).

1.4.2 OPERATION WITH DATALOGGERS WITH OLDER PROMS AND NON-DATALOGGER DEVICES (PRINTER ENABLE METHOD)

In the Printer Enable Method (Figure 1.4-2), the
Storage Module stores all data received (on pin

9) while the printer enable line (pin 6) is high.
The Storage Module baud rate must be set to
match that of the sending device (Section

1.4.5). The datalogger cannot detect if the SM
is connected. Data are sent whether or not the
SM is connected.

Data can be stored in the SM under program
control (Instruction 96 or *4) or under user
control (*9 Mode). Operations with the CR21,
the DSP4 Heads Up Display and with non­datalogger devices (Appendix C) are also
accomplished through the Printer Enable
Method (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 (Figure

1.4-3). TELCOM (PC208 software) uses the
Telecommunications Commands for data
retrieval, data storage, storage and retrieval of
datalogger programs, SM software switch
setting, status checks, battery tests and other
functions (Section 5). The commands used by
TELCOM are described in Appendix D.

1.4.1 OPERATION WITH CURRENT CR10, 21X, AND CR7

Storage Module operations with the current
versions of the CR10, 21X, and CR7 are
accomplished through the use of an interactive
command structure with handshaking (Figure

1.4-1). If the SM is not connected, the
datalogger will not send data. The datalogger
detects when the SM is connected, and sends
the backlogged data the next time it executes
Instruction 96.

SECTION 1. SM192/716 STORAGE MODULE OVERVIEW

1.4.4 MEMORY CONFIGURATION

The Storage Module's memory can be
configured as either Fill and Stop or Ring style
memory. In the Fill and Stop configuration, the
Storage Module stops accepting data when its
memory is full. No data write-over occurs. In
the Ring Memory configuration (the default
setting), new data continue to be stored even
after the memory is full. New data are written
over the oldest data in the memory. The
Storage Module's memory configuration can be
changed using SMCOM or with Command 4 in
the CR10 *9 Mode.

1.4.5 BAUD RATES

When storing CR7, CR10, and 21X data, the
Storage Module is set for its default baud rate of
76,800/9600; baud rate matching is automatic
and requires no user intervention. Data transfer
takes place at 9600 baud.

With other devices, the baud rates of the device
and the Storage Module must be matched by
the user. Storage Module choices are: 300,
1200, 9600, 76,800, and 76,800/9600 (Section

4.1). With the CR21, the SM must be set to 300
baud. When using the Telecommunications
Commands, sending several carriage returns
will cause the Storage Module to match the
computer's baud rate (300, 1200, or 9600
baud).

1.4.6 FILE MARK

File Marks are used to separate data in the
Storage Module. A File Mark is automatically
placed in the SM's memory when the SM 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 SM 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 be placed in the data from
SMCOM or the CR10 *9 Mode Command 3.
The Storage Module will not store back to back
file marks; if a File Mark is the last thing stored
in memory, a second file mark will not be
stored.

1.5 QUICK START-UP PROCEDURE

This Section describes the basics of storing and
retrieving of 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 SMCOM to
reset the SM and test its battery.

If it is not possible to use a PC compatible
computer and SMCOM, the user must establish
communication between the SM, the available
computer, or terminal (Section 5) and reset the
SM using the Telecommunications Commands
(Appendix D) or use the *9 Mode in the CR10
(Appendix A).

1.5.2 PROGRAM THE DATALOGGER TO SEND DATA TO THE SM

Instruction 96 is used in the datalogger program
to send data to the Storage Module. The SM is
connected to the datalogger with the SC12
cable. Each time Instruction 96 is executed,
Final Storage data accumulated since the last
transfer are sent to the Storage Module.

For the CR7 and 21X WITHOUT Instruction 96
the *4 Mode is used to enable output to a
printer. The CR21 automatically outputs printer
data at 300 baud each time data is sent to Final
Storage.

The DSP4 outputs printer data when the printer
function is enabled.

1.5.3 MANUAL DUMP

The *8 Mode in the CR10 or the *9 Mode in the
21X and CR7 can be used to transfer data to
the SM under keyboard control. All of the
above options are discussed in greater detail in
Section 4.

1.5.4 DATA RETRIEVAL

The simplest method of retrieving data from the
Storage Module is to use SMCOM. SMCOM is
contained in Campbell Scientific's PC208
software. It is written for IBM PC/XT/AT/PS-2's
and compatibles. If the user has another type
of computer, the SM telecommunications
commands can be used to retrieve the data.
Data retrieval (including interface devices) is
discussed in Section 5.
