5.2 REMOTE PROGRAMMING OF THE
CR23X
Remote programming of the CR23X can be
accomplished with the PC208W software or
directly through the Remote Keyboard State.
The PC208W 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 in PC208W or the
separate Short Cut program generator) and
downloaded to the datalogger using PC208W’s
Connect screen.
Alternatively, a terminal session can be opened
using any terminal program (e.g., Microsoft’s
Hyperterminal) and connecting via serial cable to
the CR23X. PC208W’s Connect screen also
offers such a Terminal window. The CR23X can
be placed in the Remote Keyboard State by
sending either "7H" or "2718H" and a carriage
return (CR). The CR23X responds by sending a
CR, line feed (LF), and the prompt '>'. The
CR23X is then ready to receive the standard
keyboard commands; it recognizes all the
standard CR23X keyboard characters plus
several additional characters, including the
decimal point, the minus sign, and Enter (CR)
(Section OV3.2).
NOTE: Entering * 0 returns the CR23X to
the telecommunications command state.
Remember that entering * 0 will compile and
run the CR23X program if program changes
have been made.
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.
The user can step back and forth between the
Telecommunications Command State and the
Remote Keyboard State.
