DataView II (CD295) Dual Line Display
1. Introduction
The DataView II is a two line, 32 character LCD that displays real time values
from a CR2xx series datalogger along with a pre-defined description string and
units string.
Two buttons allow the user to scroll through the programmed locations that are
updated as often as they are measured. When the user has not pressed a button
within a user-defined period (default 120 seconds), the DataView II switches
to low power mode, drawing a current of less than 1mA.
The DataView II is easily configured using the Windows based PC295W and
DevConfig packages.
NOTE
Throughout this document the terms ‘DataView II’, ‘CD295’
and ‘DataView2’ are used interchangeably.
1.1 Changes from Version 1 to Version 2
The original release of the CD295 operating system (V1.0) and PC295 (V1.0)
supported the CR200-series dataloggers only. Version 2 of the CD295
operating system and PC295 added support for our CR1000, CR800, CR850,
and CR3000 dataloggers, as well as support for their new data types (long
integers, Booleans, strings, and time stamps).
To use the new capabilities, both the CD295 operating system (OS) and PC295
software needs to be upgraded to Version 2. Refer to Section 4.2.1.4 to
upgrade the CD295 OS. To upgrade PC295, uninstall previous software
versions and then follow the procedure provided in Section 3.2.
1.2 Normal Operation Overview
Below is a general description of normal operation of the DataView II
(CD295).
When first powered up, the DataView II displays the following greeting,
Campbell
Scientific
and the backlight will be lit.
After a program has been successfully downloaded, the CD295 is configured
and connected to the datalogger; it is ready for general use. Pressing one of the
buttons on the CD295 will cause the LCD to display something like the
example below.

DataView II (CD295) Dual Line Display
Description
Temperature
1.234 deg C
The top line contains a string referred to as the ‘Description’, and the second
line contains both the value retrieved from a Public Variable in the datalogger
and a string referred to as ‘Units’. The value displayed on the second line can
be displayed with a user-selectable number of decimal places.
Together, the combination of ‘Description’, Public Variable, ‘Units’ and
number of decimal places, is referred to as a ‘screen’. The CD295 is capable of
holding and displaying up to 30 ‘screens’. There are no limitations on the order
of screens, or which Public Variables are displayed. Pressing the buttons on the
front panel of the DataView II will cause the next (or previous) screen to be
displayed.
The CD295 will attempt to collect a new value from the datalogger under the
following conditions:
• The user has changed ‘screen’
Value
Units
• The scan interval of the datalogger has expired
After some time (default 10 secs), the backlight will turn off, however the text
will remain visible until the unit enters sleep mode (default 120 secs).
Whenever one of the buttons on the front panel is pressed, these two timers
(Backlight timer and Power Down timer) are both reset. As a result, the
DataView II can be woken from sleep mode by pressing either of the buttons.
While in sleep mode the DataView II will continue to respond to PakBus
communications, however the LCD is turned off and no requests are sent to the
datalogger.
2. Installation Procedure
Below is a general guide to the steps involved in configuring and programming
a DataView II (CD295)
1. Using the CD from the CD295 shipping kit, install PC295W and
DevConfig on your computer.
2. Connect the programming cable’s 9-pin D-connector into the CD295 data
cable and the other end into your PC’s serial COM port.
3. Using PC295W and the datalogger program, configure your screens of
your DataView II (DV2 file).

4. Using DevConfig send the DataView II program (DV2 file), and change
any settings (e.g., PakBus Address).

5. Remove the programming cable.
6. Mount the CD295 into your datalogger enclosure.
7. Connect the CD295 data cable to the datalogger’s RS-232 port.
8. Power-up the datalogger and CD295 and verify correct operation.

3.2 Software Installation
1. To begin the installation of the PC295 software, insert the PC295 CD into
your computer, and locate and open the setup.exe file, which contains the
software to be used.
2. After starting Setup.exe you will be presented with a welcome screen
giving a brief introduction to the software. Click OK.

3. The next screen asks where you would like PC295 installed on your hard
disk. If you wish to install into a path other than the default, click “Change
Directory” and use the windows dialog to choose a suitable location. Once
the path is correct, click the Install icon in the top left corner of the
window.
4. The next dialog to appear asks which program group on the start menu,
you would like to add PC295. The default is usually acceptable; however
if not, you are free to choose your preferred program group in this step.
Click Continue.

5. File copying will now begin.
4. Programming

6. Once the Setup is complete, the following window is displayed. You are
now ready to start using PC295. Click OK.
PC295 software is a freeware utility provided by Campbell Scientific Australia
to write programs for the DataView II.
PC295 first reads the datalogger program, to generate the list of Public
Variables and to determine the scan rate of the datalogger. Once this
information has been determined, the user is able to choose a public variable to
display, and can associate ‘Description’ and ‘Units’ strings with it to form a
‘screen’. A group of screens forms a user program, and PC295 saves this
program to disk in a DV2 file.
4.1.1 Operation
By default, the first part of the filename is the same as the datalogger program
from which it was generated. So for example, if you opened station1.cr2 to
create the DataView II program, PC295 would save the program as
station1.dv2. This naming convention is strongly recommended, but not
mandatory.
1. To start PC295, Click Start > Programs > PC295W DataView2
Programming Software > PC295W DataView2 Programming Software.

2. Once the PC295 program starts you will see the main screen.
3. The first step in creating a DataView II program is to select ‘Create new
DataView2 Program’ from the File menu. This will open a file browser
window which will allow you to locate the datalogger program (with CR1,
CR2, CR3, or CR8 extension). When the correct datalogger program is
selected, click Open.
If you already have created a DataView II program that you wish to edit,
select ‘Open Existing DataView2 Program’ in the File Menu. A file
browse window will appear. Locate your DataView II program (.295
extension), and click Open.

4. If you have chosen to ‘Create a new DataView2 program’, a file browse
window will appear.
To operate correctly, your DataView II needs some information about the
program running in the datalogger to which it will be connected.
PC295 reads the datalogger program file you select at this step, and
extracts information such as the Scan Interval and the list of Public
variable names.
Locate the datalogger program and select Open.
