Campbell Scientific SM192/SM716 Storage Modules - Manual (Page 5)

1-1
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 SPECIFICATIONS
Storage Capacity:
Model SM192 192,896 bytes
Model SM716 716,672 bytes
Dimensions: 7.9" X 3.6" X 1.5"
Weight: SM192 1.5 lbs
SM716 1.9 lbs.
Canister: Sealed stainless steel
Processor: Hitachi 6303
Operating
Temp. Range: -35°C to +65°C
(-55°C to +85°C available
as special order)
Baud Rates: 300, 1200, 9600, 76,800
Memory
Configuration: User selectable for either
ring style or fill and stop.
Default is ring style.
Power Requirements 5 ±0.4 VDC @
100 mA (max.)
Active Processing 18 mA (avg.)
Low Power Standby State 250 µA (avg.)
Memory Backup Battery 3.5 VDC Lithium
Thionyl Chloride
Maintenance: There are no user serviceable
parts in the Storage Module. If
the SM is not exposed to
prolonged temperature
extremes while disconnected
from a primary power source,
the battery will probably last 6
yrs. The Storage Module must
be returned to the factory for
battery replacement.
