Instruction manual

SECTION 5. STG MODULE: SMS - STORAGE MODULE SOFTWARE
PC208W, Version 3.0, Instruction Manual 5-5
The above shows that the target address need
not represent the
actual address of the Storage
Module. The physical address of the Module is
shown on the “Advanced” status page.
Changing the physical module address will not
change the selected target address, and, in
fact, changing the physical address will not have
any noticeable effect until you disconnect from
the Storage Module.
Connect/Disconnect
After connecting your storage module and
selecting the required COM port and baud rate,
click on the Connect button to establish
communication between the computer and the
storage module. If everything is satisfactory, a
successful communications link will be
established and the wording on the Connect
button will change to “Disconnect”.
If your first attempt at connection fails and an
error message “Cannot connect to CSM1” or
“Communications Problems:...” appears, try to
connect again (by clicking the Connect button).
It may take some time (up to 30 seconds) to
establish the connection. The most likely cause
of a failed communication link is a loose
physical connection between the storage
module and the computer.
5.3 STATUS INFORMATION
5.3.1 STATUS BOX/UPDATE STATUS
When successful communication has been
established, a set of values will appear in the
StatusBox at the right-hand-side of the screen.
This screen shows the current status (values)
for the card or module. Some typical values are
shown in Figures 5-1 and 5-3 above.
The information in the main StatusBox is
relatively straightforward and is generally similar
for all modules. The SM192/716 module has an
additional Switch Settings information box which
shows the settings made using the ADVANCED
SETTING screen. Further information on each
item in the STATUS screen can be obtained by
clicking on that item to utilize the on-line help
system.
The status information can be updated at any
time by clicking the Update Status button.
Additional information is also available in the
appropriate Storage Module Manual.
5.3.2 ADVANCED STATUS INFORMATION
The ADVANCED STATUS screen is different
for each type of module, and provides extra
information and configuration facilities.
CSM1/MCR1
Display Pointer
The Display Location Pointer (DLP) indicates
the location which holds the first value which will
be read when extracting data from the card.
The pointer can be positioned anywhere within
the readable area of the card, either by typing
the location directly into the window or by using
the up/down arrows to increment the value. The
green arrow moves the pointer to successive
filemarks.
NOTE: If the Display Pointer points to a
filemark or the start of a program no data
will be output in response to the “Get One”
request. It must be moved past the filemark
to get further data.
Further details on Filemarks and Pointers can
be found in the relevant Storage Module Manual
and the on-line help system.
Card Format Type
This is a format code for the card currently in
use. It is an internal reference for use by
Campbell Scientific and so has no significance
for the end-user.
PROM Details
The PROM checksum calculates a unique
signature for that PROM version. For all
storage devices the PROM checksum is
displayed on the ADVANCED screen. At start-
up the value may be displayed as a series of
??????. The true value can be shown by
clicking the Re-Calculate Checksum button.
Once displayed, this value is latched and will
normally remain until you disconnect or remove
power from the storage module. You can
recheck the value at any time by clicking the
Re-Calculate Checksum button.
