CR510 OVERVIEW
OV-8
OV3. COMMUNICATING WITH CR510
An external device must be connected to the
CR510's Serial I/O port to communicate with the
CR510. This may be either Campbell
Scientific's CR10KD Keyboard Display or a
computer/terminal.
The CR10KD is powered by the CR510 and
connects directly to the serial port via the SC12
cable (supplied with the CR10KD). No
interfacing software is required.
Computer communication and program editing
is accomplished using Campbell Scientific's
datalogger support software. This package
contains a program editor (EDLOG), datalogger
communications, automated
telecommunications data retrieval, a data
reduction program, and programs to retrieve
data from Campbell Scientific Storage Modules.
To participate in the programming examples
(Section OV5) you must communicate with the
CR510. Read Section OV3.1 if the CR10KD is
being used or Section OV3.2 if datalogger
support software is being used.
OV3.1 KEYBOARD/DISPLAY
The SC12 cable (supplied with the CR10KD) is
used to connect the Keyboard/Display to the 9
pin Serial I/O port on the CR510.
If the Keyboard/Display is connected to the
CR510 prior to being powered up, the "HELLO"
message is displayed while the CR510 checks
memory. The total size of memory is then
displayed (256 for 256 K bytes of memory).
When the CR10KD is plugged in after the
CR510 has powered up, the display is
meaningless until "
∗
" is pressed to enter a
mode.
This manual describes direct interaction with
the CR510. If you have a CR10KD, work
through the direct programming examples in
this overview in addition to using EDLOG and
you will have the basics of CR510 operation as
well as an appreciation for the help provided by
the software.
OV3.1.1 FUNCTIONAL MODES
CR510/User interaction is broken into different
functional MODES (e.g., programming the
measurements and output, setting time,
manually initiating a block data transfer to
Storage Module, etc.). The modes are referred
to as Star (
∗
) Modes since they are accessed by
first keying
∗
, then the mode number or letter.
Table OV3.1-1 lists the CR510 Modes.

OV3.1.2 KEY DEFINITION
Keys and key sequences have specific
functions when using the CR10KD keyboard or
a computer/terminal in the remote keyboard
state (Section 5). Table OV3.1-2 lists these
functions. In some cases, the exact action of a
key depends on the mode the CR510 is in and
is described with the mode in the manual.
