sent to an array based
datalogger. For a list of the commands and their
meanings see the datalogger
operator’s manual.
BMP1 packet received A BMP1 packet was
received from the
device. (CR10X-TD type
devices only)
RPC packet exchanged A BMP3 packet was
exchanged. (CR5000,
CR9000 dataloggers
only)
Datalogger did not respond to
end command The computer tried to
terminate the connection
but the datalogger did
not acknowledge the
shutdown. This is an indication that there is a
communications problem between
the computer and the datalogger.
Check the cables and connectors
and make sure the datalogger has
power.
Invalid low level signature The packet received
from the device got
corrupted and the packet
signature doesn’t match
the packet contents. Check to find out where in the
communications link noise or signal
corruption is causing the data to be
disrupted.
Provider opened The serial
communications port has
been initialized.
Device dialed The communications
link has been initialized
to transfer data packets.
Provider closed The serial
communications port has
been closed.
Unable to Locate Serial synch
byte The low level
communications
synchronization byte
was not received after
the computer sent out a
serial packet. This indicates that the device is
either not responding or responding
with an invalid communications
protocol. This message would
appear if trying to talk to an array
based datalogger that is set up as a
table based datalogger in the
network map.
