3142J TOGGLE FLAGS AND SET UP FOR K COMMAND - Used in the
Monitor Mode and with the Heads Up Display. See Appendix C for
details.
K CURRENT INFORMATION - In response to the K command, the
CR510 sends datalogger time, user flag status, the data at the input
locations requested in the J command, and Final Storage Data if
requested by the J command. Used in the Monitor Mode and with
Heads Up Display. See Appendix B.
[Password]L Unlocks security (if enabled) to the level determined by the password
entered (See
∗
C Mode, Section 1.7). CR510 sends security level (0-3)
and checksum: Sxx Cxxxx
[X]M Connect to Storage Module with address 'X' and enter the Storage
Module's Telecommunications Mode (see Storage Module manual).
The Storage Module can also be accessed through the
∗
9 Commands
while in the Remote Keyboard (Section 4.5 and the Storage Module
manual).
1N Connect phone modem to RF modem at phone to RF base station
(requires 1200 baud communication).
5.2 REMOTE PROGRAMMING OF THE
CR510
Remote programming of the CR510 can be
accomplished with the datalogger support
software or directly through the Remote
Keyboard State.
The datalogger support software was developed
by Campbell Scientific for use with IBM or
compatible PC's. Datalogger programs are
developed on the computer using the program
editor and downloaded to the datalogger with
the terminal emulator program.
The CR510 is placed in the Remote Keyboard
State by sending either "7H" or "2718H" and a
carriage return (CR). The CR510 responds by
sending a CR, line feed (LF), and the prompt '>'.
The CR510 is then ready to receive the standard
keyboard commands; it recognizes all the
standard CR510 keyboard characters plus
several additional characters, including the
decimal point, the minus sign, and Enter (CR)
(Section OV3.2). ENTERING
∗
0 RETURNS
THE CR510 TO THE TELECOMMUNICATIONS
COMMAND STATE.
Remember that entering
∗
0 will compile and run
the CR510 program if program changes have
been made. If the CR10KD is connected it will
just display "LOG" when
∗
0 is executed via
telecommunications. It will not indicate active
tables (keying "
∗
0" on the Keyboard/Display will
show the tables).
The 7H Command is generally used with a
terminal for direct entry since H makes use of a
destructive backspace and does not send
control Q between each entry. The 2718H
Command functions the same as it does for
other Campbell Scientific dataloggers (deleting
an entry causes the entire entry to be sent,
"control Q" is sent after each user entry).
It is important to remember that the Remote
Keyboard State is still within
Telecommunications. Entering
∗
0 exits the
Remote Keyboard State and returns the
datalogger to the Telecommunications
Command State, awaiting another command.
So, the user can step back and forth between
the Telecommunications Command State and
the Remote Keyboard State.
