CS725 Snow Water Equivalency Sensor
After the memory is allocated (within 1 minute), the CS725 will prompt for the
file transfer with the following message:
Launch the file transfer with the Hyper Terminal
If you are using HyperTerminal, select “Send Text File…” from the Transfer
menu.
The supplied programming file will need to be selected and sent to the CS725.
The process will take approximately 5 minutes at 57600 bps and in excess of
30 minutes at 9600 bps. If the scrolling characters stop for a long duration, it is
possible that an error occurred in communications. Shut down Hyperterminal,
power down the CS725, and restart the process again.
A single line of scrolling data will be displayed as the transfer takes place.
Once the transfer is complete, the following text will be displayed on the
terminal:
Transfer completed; type w to overwrite the EPROM memory, type . to
abort
Once the following step is done, it is critical to not
interrupt this process or power down the CS725. If
the process is interrupted, the CS725 may need to
be sent back to the factory for reprogramming. CAUTION
Type in the character w followed by the enter key “w<Enter>”.
After the w command is entered, the terminal will display that the
programming has begun and the progress will be displayed as follows:
Begin EPROM programming
Erasing block 0x0
Writing EPROM from 0x0 to 0xffff
Upon completion the CS725 will prompt to be reset. It is recommended to
cycle power only after the following message is displayed:
Programming done .. cycle power on the GMONIII, or do a Hard Reset
It is recommended to restart Hyperterminal as well and change the baud rate
setting back to 9600 bps and to disable the XON/XOFF flow control to resume
normal communications and verify that the CS725 powers up properly and
retained its parameter settings.
