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 retained 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.
SM192/SM716
The SM192/716 ADVANCED STATUS screen is similar to the CSM1 screen,
but has additional configuration facilities. These are listed below.
Print Enable Mode
Data from 21X and CR7 dataloggers with older PROMs, and data from non-
datalogger devices are stored in the Storage Module using the “ Print Enable”
mode. Full details of this storage method can be found in the SM192/716
Instruction Manual.
Baud Rate – Print Enable Mode
This is the printer baud rate when data are collected by the Printer Enable (PE)
method. For this method of collection you must ensure that the baud rate of the
Storage Module and the datalogger are matched. Most Campbell Scientific
dataloggers have selectable baud rates. You can select the baud rate using the
Baud Rate setting box in the Print Enable Mode section. The SM192/716
Instruction Manual gives further details.
The 76,800/9600 setting is the default after an SM reset. In this
setting the SM can automatically change from capturing data at
76,800 baud to capturing data at 9600 baud. Baud rate errors
(baud rate mismatches between SM and datalogger) cause the
SM to increment its error counter and enter a low power standby
state.
