SECTION 5. TELECOMMUNICATIONS

KCURRENT INFORMATION - In response to the K command, the CR10 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 C.

[Password]L Unlocks security (if enabled) to the level determined by the password entered (See *C Mode, Section 1.7). CR10 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 4.6 and the Storage Module manual).

Connect phone modem to RF modem at phone to RF base station.

5.2REMOTE PROGRAMMING OF THE CR10

Remote programming of the CR10 can be accomplished with the PC208 software or directly through the Remote Keyboard State.

The PC208 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 (EDLOG) and downloaded to the datalogger with the terminal emulator program (GraphTerm).

The CR10 is placed in the Remote Keyboard State by sending either "7H" or "2718H" and a carriage return (CR). The CR10 responds by sending a CR, line feed (LF), and the prompt '>'. The CR10 is then ready to receive the standard keyboard commands; it recognizes all the standard CR10 keyboard characters plus several additional characters, such as the decimal point and the minus sign (Section OV3.2). ENTERING *0 RETURNS THE CR10

TO THE TELECOMMUNICATIONS COMMAND STATE.

State

Remember that entering *0 will compile and run the CR10 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) and its use will be familiar to those already working with a 21X or CR7X.

It is important to remember that the Remote Keyboard State is still within Telecommunications. Entering *0 exits the Remote Keyboard 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 Mode.
