A.4 Device Configuration Utility
The Device Configuration Utility software may also be used to change settings,
although ECMon is generally preferred as the user interface is more intuitive.
Device Configuration may be downloaded from the EC150 & EC155 Support
CD (pn 27007), or at
Device Configuration requires a USB driver to communicate with the EC100,
similar to ECMon. See Appendix A.3, ECMon, for notes on installing a USB
driver.
After launching the
Device Configuration Utility, the user should select
EC100 from the list of device types. The EC100 electronics should be
connected to the PC with the EC100 USB cable (pn 26563) and the appropriate
USB port selected before connecting. Once connected, the settings tab
displays all the current settings. The
Apply button must be clicked to save any
changes.
The Device Configuration Utility is also used to send an updated operating
system to the EC100 electronics. The
Send OS tab gives directions on this
procedure. For a video tutorial on updating the operating system, a video
tutorial is available at
A.5 EC100Configure() Instruction
EC100Configure() is an alternate way to retrieve and modify setting. While
ECmon and Device Configuration Utility software are user-interactive, the
EC100Configure() instruction allows automated control under CRBasic
datalogger programming.
EC100Configure() is a processing task instruction. When running in pipeline
mode, the datalogger will execute the instruction from the processing task.
This functionality allows the instruction to be placed in conditional statements.
Execution from processing also introduces ramifications when attempting to
execute the
EC100Configure() instruction while other SDM instructions are
executing in pipeline mode. This instruction locks the SDM port during the
duration of its execution. If the pipelined SDM task sequencer needs to run
while the SDM is locked, it will be held off until the instruction completes.
This locking will likely result in skipped scans when reconfiguring an EC150.
For the EC150 to save settings, it must go through a lengthy write-
read-verify process. To avoid saving the settings after each set
command, the resulting code can be used to determine if any
settings were modified from their original value. When a change
is detected, the save settings command (command code
99) can
then be sent to the EC150. The DestSource parameter variable
should be set to
2718 to save the settings. The reception of this
command is acknowledged but since it takes up to a second to
complete, a successful return code does not mean that all of the
data was successfully written to the appropriate non-volatile
memory.
